a8ae31c2 UD |
9 | Version 2.2.5 |
10 | ||
11 | * Stephen Moshier implemented powl and cbrtl for the 128-bit | |
12 | long double format. | |
13 | ||
557a9213 UD |
14 | * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160, |

a8ae31c2 UD |
16 | |
17 | * Andreas Jaeger contributed a port to x86_64/Linux. | |
18 | ||
19 | * libc functions using I/O streams now can handle wide-oriented streams | |
20 | as well. | |
21 | ||
95eaff64 UD |
22 | * optimizations in the dynamic linker. binaries created by recent binutils |
23 | versions start up quicker due to reduced time spend on relocations. | |
24 | ||

25 | Version 2.2.4 |
26 | ||
2995f70e | 27 | * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, |
aff17a50 | 28 | asinh, atanh, j0 for the 128-bit long double format. |
8fee1bb0 UD |
29 | |
30 | * Bruno Haible updated all the code handling Unicode in some form to | |
31 | support Unicode 3.1. | |
86dbe05e UD |
32 | |
33 | * Speed of regex for single-byte locales is back to previous levels. | |
34 | Patch by Isamu Hasegawa. | |
045fcd26 | 35 | |
69d5f925 | 36 | * Alpha, SPARC, and IA-64 now also using floating stacks. |
045fcd26 | 37 | |
69d5f925 | 38 | * Startup time of internationalized applications greatly improved through |
045fcd26 UD |
39 | iconv cache. Use iconvconfig to generate the cache file. |
40 | Contributed by Ulrich Drepper. | |
41 | ||
42 | * The IA-64 specific part of ld.so was rewritten to eliminate some pretty | |
43 | severe performance problems. Patch by David Mosberger. | |
44 | ||
45 | * The Hurd port got a lot more functionality like AIO, various stdio | |
46 | extensions, etc. Mainly done by Roland McGrath. | |
129d706d UD |
47 | |
48 | * mtrace can now lookup symbols in shared libraries. | |
33996419 | 49 | \f |
2ace5721 UD |
50 | Version 2.2.3 |
51 | ||
1746f2b0 | 52 | * Intel's IA-64 math library is largely integrated. It provides fast and |
2ace5721 UD |
53 | accurate implementatations for most basic and standard math functions |
54 | in float, double, and long double format. | |
55 | ||
f128331c | 56 | * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, |
b8750342 UD |
57 | and asin for the 96-bit long double format and asin, log, tan for the |
58 | 128-bit long double format. | |
07f951e4 | 59 | |
e4d82761 UD |
60 | * The beginning of a last-bit accurate math library by IBM Haifa were added. |
61 | The basic double functions exist today. Contributed by Abraham Ziv | |
62 | <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis | |
63 | <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. | |
64 | ||
2ace5721 UD |
65 | * An asynchronous name lookup library was added. The interface is designed |
66 | after POSIX AIO. The proposal was circulated beforehand to get comments. | |
67 | No negative ones came in. Implemented by Ulrich Drepper. | |
b8a8413c UD |
68 | |
69 | * Port to S390/64bit contributed by Martin Schwidefsky | |
70 | <schwidefsky@de.ibm.com>. | |
a66f0958 UD |
71 | |
72 | * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family | |
73 | of functions for Linux/IA-64. | |
481b550f UD |
74 | |
75 | * The RPC code is now thread safe. Threads can now use the same service | |
76 | of different services at the same time. Patch by Eric Norum | |
77 | <eric.norum@usask.ca> with some help by Ulrich Drepper. | |
f128331c UD |
78 | |
79 | * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext | |
80 | family of functions for Linux/S390. | |
232fdf8c UD |
81 | |
82 | * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family | |
83 | of functions for Linux/x86. | |
eacde9d0 UD |
84 | |
85 | * Port to Linux/CRIS contributed by Axis Communications. | |
2ace5721 | 86 | \f |
306eeae5 UD |
87 | Version 2.2.2 |
88 | ||
464d97ec | 89 | * Lots of headers were cleaned up. Using the tool in the conform/ subdir |
306eeae5 UD |
90 | we can now check for namespace violations and missing declarations. The |
91 | result is that almost all headers are now Unix-compliant (as defined in | |
92 | the upcoming XPG6). The negative side is that some programs might need | |
93 | corrections, too, if they depend on the incorrect form of the headers in | |
94 | previous versions which defined too many symbols and included too many | |
95 | other headers. | |
464d97ec UD |
96 | |
97 | * regex now handles multibyte character sets correctly. | |
98 | Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. | |
99 | ||
100 | * iconv (the program) does now conform to the upcoming XPG6 and handles | |
101 | charmaps. Instead of the charset names the path of charmaps can be | |
102 | provided and the conversion happens based on this data. | |
103 | Contributed by Ulrich Drepper. | |
104 | ||
105 | * The locale program now provides detailed information about the installed | |
106 | locales. While | |
107 | ||
108 | locale -a | |
109 | ||
110 | only lists the names of the supported locales | |
111 | ||
112 | locale -a --verbose | |
113 | ||
114 | provides details such as country, language, and codeset name. | |
115 | Contributed by Ulrich Drepper. | |
306eeae5 | 116 | \f |
d2defdc4 UD |
117 | Version 2.2.1 |
118 | ||
119 | * The gencat program now parses the input file according to the charset | |
120 | selected by the LC_CTYPE category. This is important for stateful | |
121 | character sets. To make generating catalogs easier there is a way | |
122 | to overwrite the charset selected by the locale: before the first | |
123 | message or $ quote line the catalog can contain a line like | |
124 | ||
125 | $ codeset=ISO-8859-2 | |
126 | ||
127 | to select the charset (ISO-8859-2 in this case). | |
128 | ||
129 | Implemented by Shinya Hanataka and Ulrich Drepper. | |
aea6353a UD |
130 | |
131 | * New codeset conversion modules: IBM-922 (Estonia PC codeset), | |
132 | IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). | |
133 | Contributed by Masahide Washizawa <washi@jp.ibm.com>. | |
234669e2 UD |
134 | |
135 | * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson | |
136 | <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. | |
137 | ||
138 | * The LANGUAGE environment variable is now ignored unless the locale is | |
139 | changed from the default "C" locale. | |
140 | ||
141 | * The usual bug fixes. | |
d2defdc4 | 142 | \f |
2e92188d UD |
143 | Version 2.2 |
144 | ||
08a2e4a0 GM |
145 | * Greg McGary added runtime support for bounds checking using gcc's |
146 | new -fbounded-pointers option. ix86 target is complete. PowerPC | |
147 | is in progress. | |
148 | ||
2e92188d UD |
149 | * Thorsten Kukuk added secure mode support to nscd. |
150 | ||
793bd4d9 | 151 | * The Berkeley db libraries have been removed. |
2e92188d | 152 | |
47b853e8 UD |
153 | Related, the nss_db module is now in a separate package since it |
154 | obviously requires a database library being available. | |
155 | ||
0013b2b1 UD |
156 | * Wide character I/O streams implemented by Ulrich Drepper. |
157 | ||
abbffdf9 | 158 | * Functions from the extended socket API added by Ulrich Drepper. |
01c771d0 | 159 | |
6e8afc1c UD |
160 | * Functions feenableexcept and fedisableexcept to control the |
161 | behaviour of individual exceptions have been added by Andreas Jaeger. | |
162 | ||
591e1ffb UD |
163 | * ldconfig program added by Andreas Jaeger and Jakub Jelinek. |
164 | ||
d3436b3c UD |
165 | * The resolver code has been updated from bind 8.2.3-T5B which supports |
166 | threads. The integration was done by Andreas Jaeger, Adam D. Bradley, | |
167 | and Mark Kettenis. | |
2588068b UD |
168 | |
169 | This change could in some situations effect backward compatibility. Since | |
170 | now `_res' is a thread-local instead of a global variable, modifying it | |
171 | in one thread does not have any effect in other threads. | |
66ac0abe | 172 | |
a00c3ca9 | 173 | The resolver library was also extended to allow IPv6 as the transport |
d3436b3c UD |
174 | protocol for the requests. This work was done by Stig Venaas. |
175 | ||
1c5d4617 UD |
176 | * Compatibility code for K&R C compilers has been removed from the |
177 | header files. A ISO C compiler is needed to use the library | |
178 | (conforming to either C89 or C99 standard). | |
179 | ||
abbffdf9 UD |
180 | * Complete rewrite of the localedef program to support multibyte character |
181 | sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, | |
182 | strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. | |
183 | Implemented by Ulrich Drepper. | |
184 | ||
8f3f1e09 UD |
185 | Bruno Haible significantly improved the generation and use of the data |
186 | structures for the wide character tables. | |
187 | ||
abbffdf9 UD |
188 | * Plural handling in gettext implemented by Ulrich Drepper. |
189 | ||
69173865 UD |
190 | * The utmp daemon has been removed. |
191 | ||
192 | * The port to MIPS-Linux has been finished by Andreas Jaeger. | |
193 | ||
37fb8add UD |
194 | * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima |
195 | and Yutaka Niibe. | |
196 | ||
594cee6c UD |
197 | * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. |
198 | ||
40c4c9b5 UD |
199 | * POSIX barriers implemented by Kaz Kylheku. |
200 | ||
594cee6c UD |
201 | * POSIX spawn function family implemented by Ulrich Drepper. |
202 | ||
203 | * POSIX spinlocks are now available. | |
204 | ||
40c4c9b5 UD |
205 | * Timed wait functions for mutex, rwlock, and semaphores are implemented. |
206 | ||
8f3f1e09 UD |
207 | * the configure option --enable-kernel=X.Y.Z allows to strip out |
208 | compatibility for kernel versions before X.Y.Z. This is currently only | |
209 | implemented for Linux. | |
210 | ||
3107c0c5 UD |
211 | * the sockaddr_in6 structure changed. The IPv6 working group added a new |
212 | field sin6_scope_id. This means that all programs using IPv6 should be | |
213 | recompiled. Don't expect binary compatibility with previous glibc | |
214 | versions. | |
215 | ||
d2830ba4 UD |
216 | * various conversion modules for IBM character sets contributed by |
217 | Masahide Washizawa. | |
218 | ||
8f3f1e09 UD |
219 | * IA-64 port by Jes Sorensen and HJ Lu. |

222 | Compiling the GNU C Library for Linux/ia64 | |
223 | ****************************************** | |
224 | ||
225 | Please refer to the file INSTALL in the same directory as you found | |
226 | this file for general information about configuring and compiling | |
227 | glibc. | |
228 | ||
229 | For general inquiries about glibc under Linux/ia64 please use the | |
230 | following mailing list linux-ia64@linuxia64.org or one of the relevant | |
231 | glibc mailing lists. | |
232 | ||
233 | Recommended Tools for Compilation | |
234 | ================================= | |
235 | ||
236 | In order for glibc-2.2 to build correctly on the ia64 you need at | |
237 | least the following versions of the GNU tools (the : | |
238 | ||
239 | * The Cygnus toolchain snapshot for the ia64 as of August 4 | |
aea6353a UD |
240 | including the provided set of patches. It is however recommend |
241 | you use the October 24 toolchain snapshot or a more recent version. | |
8f3f1e09 UD |
242 | |
243 | OR alternatively you can try the following (the Cygnus toolchain is | |
244 | the recommended solution): | |
245 | ||
246 | * GCC and binutils, GAS and GNU LD out of CVS from | |
aea6353a | 247 | sources.redhat.com as of August 28, 2000 or later. The CVS tree |
8f3f1e09 UD |
248 | may require special patches to work properly on the ia64. |
249 | ||
250 | Configuring and compiling GNU Libc for Linux/ia64 | |
251 | ================================================= | |
252 | ||
253 | The library requires Linux kernel version 2.4.0-test4-000728 or | |
aea6353a UD |
254 | later to funtion properly. Besides that it support for debug libraries |
255 | is currently untested. Hence the following options | |
8f3f1e09 UD |
256 | are required for configuring the library: |
257 | ||
aea6353a | 258 | --disable-debug --enable-kernel=2.4.0 |
8f3f1e09 UD |
259 | |
260 | It is also important that you make sure the library picks up the | |
261 | appropriate kernel header files, if you do not have recent enough | |
262 | kernel headers in /usr/src/linux/include, you should use the | |
263 | --with-headers=<path> option to specify the location. | |
264 | ||
265 | As an example I personally use the following options to configure | |
266 | the library: | |
267 | ||
268 | --disable-debug | |
8f3f1e09 UD |
269 | --disable-cvs |
270 | --enable-kernel=2.4.0 | |
271 | --host=ia64-linux | |
272 | --enable-add-ons=yes | |
273 | --prefix=/usr | |
274 | --with-headers=/home/jes/linux/include | |
275 | ||
276 | ||
277 | Good luck | |

283 | Version 2.1.3 | |
284 | ||
285 | * bug fixes | |
286 | ||
01c771d0 UD |
287 | \f |
288 | Version 2.1.2 | |
289 | ||
290 | * bug fixes | |
291 | ||
28f540f4 | 292 | \f |
e518937a UD |
293 | Version 2.1.1 |
294 | ||
27995311 UD |
295 | * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added. |
296 | ||
16b0f634 UD |
297 | * New xdr functions are added; some rpc functions are now 64bit clean. |
298 | ||
407d26b7 | 299 | * Fixed a number of bugs and memory leaks (especially in NIS+ code). |
16b0f634 UD |
300 | |
301 | * Fixed known incompatibilities with glibc 2.0. | |
302 | ||
407d26b7 | 303 | * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. |
16b0f634 | 304 | |
407d26b7 | 305 | * Optimized a number of functions (especially the ELF dynamic loader). |
16b0f634 UD |
306 | |
307 | * Update timezone data files. | |
27995311 | 308 | |
554b8800 UD |
309 | * lots of charmaps corrections |
310 | ||
311 | * some new locale definitions and charmaps | |
312 | ||
e518937a | 313 | \f |
c84142e8 UD |
314 | Version 2.1 |
315 | ||
da2d1bc5 UD |
316 | * Richard Henderson corrected size of struct timeval on Linux/Alpha to |
317 | conform to POSIX member type requirements. Symbol versions have been | |
318 | adjusted as needed within the library, and for direct use by applications, | |
319 | but there is potential for problems if third-party libraries use | |
320 | struct timeval as part of their interface. This does not present | |
321 | a problem for X and other "essential" system libraries. | |
322 | ||
c84142e8 | 323 | * An additional locale model to support C++ Standard Library locale |
1fb05e3d | 324 | model and probably more was implemented by Ulrich Drepper. |
c84142e8 | 325 | |
1fb05e3d | 326 | * Eric Youngdale and Ulrich Drepper implemented versioning of objects on |
c84142e8 UD |
327 | symbol level. |
328 | ||
329 | * Miles Bader provided the `argp' function family to support hierachical | |
330 | command line argument parsing, layered on top of getopt. | |
377a515b | 331 | |
cbdee279 | 332 | * strtod accepts new hexadecimal floating-point format from ISO C 9X. |
377a515b UD |
333 | |
334 | * printf has two new specifiers %a and %A to print hexadecimal flaoting-point | |
cbdee279 | 335 | numbers. |
377a515b | 336 | |
cbdee279 | 337 | * scanf recognizes the %a and %A format for scanning floating point numbers. |
e61abf83 | 338 | |
48869012 UD |
339 | * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides |
340 | information and interfaces for the available integer types. | |
e61abf83 | 341 | |
813f4f4d UD |
342 | * about 130 new math functions were added to implement the ISO C9x math |
343 | library. | |
344 | ||
e61abf83 | 345 | * the new header <complex.h> contains definitions of the complex math |
cbdee279 UD |
346 | functions from ISO C 9X. |
347 | ||
348 | * the new header <tgmath.h> defines generic macros to use complex or | |
349 | real valued functions. | |
e61abf83 | 350 | |
a5a0310d | 351 | * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2. |
e61abf83 | 352 | |
a5a0310d UD |
353 | * Andreas Jaeger provided a test suite for the math library. |
354 | ||
355 | * Mark Kettenis implemented the utmpx interface and an utmp daemon. | |
cbdee279 | 356 | |
440d13e2 | 357 | * Ulrich Drepper added character set conversion functions (iconv). |
cbdee279 UD |
358 | |
359 | * Optimized string functions have been added. | |
360 | ||
361 | * The localedata addon is now part of glibc. | |
2eb45444 UD |
362 | |
363 | * An implementation of profiling shared libraries was added by Ulrich Drepper. | |
ea278354 | 364 | |
48244d09 UD |
365 | * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching |
366 | daemon for NSS (nscd). | |
367 | ||
368 | Missing a better place here are some numbers on improvements. Under | |
369 | Linux 2.1.125 un-tar-ing the kernel sources takes | |
370 | ||
0dee6738 | 371 | user system wall |
48244d09 | 372 | |
0dee6738 | 373 | using local files 12.19s 6.88s 22.91s |
48244d09 | 374 | |
0dee6738 | 375 | using NIS 13.92s 8.91s 26.34s |
48244d09 | 376 | |
0dee6738 | 377 | using NIS & nscd 10.37s 7.34s 25.30s |
48244d09 | 378 | |
0dee6738 UD |
379 | using NIS+ 27.57s 30.37s 640.46s |
380 | ||
381 | using NIS+ & nscd 10.25s 7.83s 26.51s | |
382 | ||
383 | using NIS & old nscd [1] 13.83s 8.32s 29.60s | |
48244d09 | 384 | |
48244d09 UD |
385 | Keep in mind that non-namelookup related operations dominate above times. |
386 | It was just a common complain that using NIS+ unpacking the kernel is | |
0dee6738 | 387 | horribly slow. |
48244d09 | 388 | |
0dee6738 UD |
389 | [1] The old nscd implementation is not available anymore since it was |
390 | distributed with glibc up to version 2.0.98 and thus is now replaced. | |
ea278354 UD |
391 | |
392 | * Tim Waugh provided an implementation of the POSIX.2 wordexp function family. | |
48869012 UD |
393 | |
394 | * Mark Kettenis provided a Hesiod NSS module. | |
20833331 UD |
395 | |
396 | * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN | |
397 | and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper). | |
398 | ||
399 | * rcmd can now handle netgroups (Dick Streefland). | |

40a4b79f | 789 | Version 2.0 |
28f540f4 | 790 | |
d3669add RM |
791 | * GNU extensions are no longer declared by default. To enable them you |
792 | must define the macro `_GNU_SOURCE' in your program or compile with | |
793 | `-D_GNU_SOURCE'. | |
794 | ||
28f540f4 RM |
795 | * The library has changed from using GNU ld symbol aliases to using weak |
796 | symbols where available. The ELF object file format supports weak | |
797 | symbols; GNU ld also supports weak symbols in the a.out format. (There | |
798 | is also now support for other GNU ld extensions in ELF. Use the | |
787126fe RM |
799 | `--with-elf' option to configure to indicate you have ELF, and |
800 | `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion | |
28f540f4 RM |
801 | of many files which contained only symbol aliases, reducing the size of |
802 | the source and the compiled library; many other files were renamed to | |
803 | less cryptic names previously occupied by the symbol alias files. | |
dcf0671d UD |
804 | There is a new header file <elf.h> for programs which operate on |
805 | files in the ELF format. | |
49e522bf RM |
806 | |
807 | * Converted to Autoconf version 2, so `configure' has more options. | |
808 | Run `configure --help' to see the details. | |
809 | ||
810 | * The library can now be configured to build profiling, highly-optimized | |
b25c5d66 RM |
811 | (but undebuggable), and/or shared libraries (ELF with GNU ld only). The |
812 | `--enable-profile', `--enable-omitfp', and `--enable-shared' options to | |
813 | `configure' enable building these extra libraries. The shared library is | |
814 | built by default when using both ELF and GNU ld. When shared libraries | |
815 | are enabled, the new library `-ldl' is available for arbitrary run-time | |
816 | loading of shared objects; its interface is defined in <dlfcn.h>. The | |
817 | new header file <link.h> gives access to the internals of the run-time | |
33a934a3 UD |
818 | dynamic linker, `ld.so'. The shell script `ldd' is similar to the |
819 | application of same name on other systems and it provides information | |
820 | about dynamically linked binaries. | |
49e522bf | 821 | |
71733723 RM |
822 | * The C library now provides the run-time support code for profiling |
823 | executables compiled with `-pg'. Programs can control the profiling code | |
d3669add RM |
824 | through the interface in <sys/gmon.h>. The `gmon.out' files written by |
825 | the GNU C library can be read only by GNU `gprof' (from GNU binutils); | |
826 | the support for this file format was contributed by David Mosberger-Tang. | |
71733723 | 827 | |
f7eac6eb | 828 | * The math code has been replaced with a math library based on fdlibm from |
33a934a3 UD |
829 | Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by |
830 | Ian Taylor with `float' functions and by Ulrich Drepper with `long double' | |
831 | functions. The math functions now reside in a separate library, so | |
832 | programs using them will need to use `-lm' their linking commands. | |
833 | ||
834 | * John C. Bowman contributed optimized ix87 assembler inline functions. | |
f7eac6eb | 835 | |
5f0e6fc7 RM |
836 | * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' |
837 | mechanism similar to that found in Solaris 2. This is now used for the | |
33a934a3 UD |
838 | group, passwd, hosts, networks, services, protocols, rpc, ethers, |
839 | shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' | |
840 | file controls what services are used for each individual database. This | |
841 | works by loading shared libraries with names specified in `nsswitch.conf', | |
842 | so service modules can be changed or added at any time without even | |
843 | relinking any program. Currently there are the file, db, and NIS based | |
844 | NSS services available. | |
5f0e6fc7 | 845 | |
49e522bf RM |
846 | * The new functions `strtoq' and `strtouq' parse integer values from |
847 | strings, like `strtol' and `strtoul', but they return `long long int' and | |
848 | `unsigned long long int' values, respectively (64-bit quantities). | |
849 | ||
850 | * The new functions `strtof' and `strtold' parse floating-point values from | |
851 | strings, like `strtod', but they return `float' and `long double' values, | |
852 | respectively (on some machines `double' and `long double' are the same). | |
853 | ||
854 | * Ulrich Drepper has contributed new implementations of the floating-point | |
855 | printing and reading code used in the `printf' family of functions and | |
856 | `strtod', `strtof', and `strtold'. These new functions are perfectly | |
857 | accurate, and much faster than the old ones. | |
858 | ||
33a934a3 UD |
859 | * The implementation of the POSIX locale model was completely rewritten by |
860 | Ulrich Drepper. This includes the new programs `localedef' and `locale' | |
861 | to compile the POSIX locale definition. | |
862 | ||
863 | * The former dummy implementations of the strcoll and strxfrm function are | |
864 | now replaced by fully functional code contributed by Ulrich Drepper. The | |
865 | collation information comes from the POSIX locale definitions. | |
866 | ||
49e522bf RM |
867 | * The new header <langinfo.h> defines an interface for accessing |
868 | various locale-dependent data (using the locale chosen with `setlocale'). | |
869 | ||
f7eac6eb | 870 | * Ulrich Drepper has contributed a new suite of functions for operation on |
33a934a3 | 871 | wide-character and multibyte-character strings, in <wchar.h>; |
b7407d63 | 872 | and classification and case conversion of wide characters, in <wctype.h>. |
33a934a3 UD |
873 | These new functions are conforming to the ISO C, Amendement 1 specification. |
874 | ||
875 | * There is now a second implementation of the standard I/O library available. | |
876 | It comes from GNU libg++ as was written by Per Bothner, heavily modified | |
877 | by Hongjiu Lu and made thread safe by Ulrich Drepper. | |
f7eac6eb | 878 | |
71733723 | 879 | * You can now use positional parameter specifications in format strings |
49e522bf RM |
880 | for the `printf' and `scanf' families of functions. For example, |
881 | `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints | |
882 | ``Number 6, Mr Jones''. This is mainly useful when providing different | |
d365fd2c RM |
883 | format strings for different languages, whose grammars may dictate |
884 | different orderings of the values being printed. To support this | |
49e522bf | 885 | feature, the interface for `register_printf_handler' has changed; see |
d365fd2c | 886 | the header file <printf.h> for details. |
49e522bf RM |
887 | |
888 | * The `printf' and `scanf' families of functions now understand a new | |
889 | formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says | |
890 | to group numbers as indicated by the locale; for `scanf' and friends, this | |
891 | says to accept as valid only a number with all the proper grouping | |
892 | separators in the right places. In the default "C" locale, numbers are | |
893 | not grouped; but locales for specific countries will define the usual | |
894 | conventions (i.e. separate thousands with `,' in the US locale). | |
28f540f4 RM |
895 | |
896 | * The pgrp functions have been regularized, slightly incompatibly but much | |
897 | less confusingly. The core functions are now `getpgid' and `setpgid', | |
898 | which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no | |
899 | argument) and BSD `setpgrp' (identical to `setpgid') functions are | |
900 | provided for compatibility. There is no longer an incompatible `getpgrp' | |
901 | with an argument declared under _BSD_SOURCE; no BSD code uses it. | |
902 | ||
903 | * The new header file <fts.h> and suite of functions simplify programs that | |
904 | operate on directory trees. This code comes from 4.4 BSD. | |
905 | ||
33a934a3 UD |
906 | * The resolver code has been updated from the BIND 4.9.5-P1 release. |
907 | Parts of the code were heavily modified by Ulrich Drepper to fit in the | |
908 | NSS scheme used in glibc. | |
28f540f4 | 909 | |
28f540f4 RM |
910 | * There is a new malloc debugging hook `__memalign_hook'. |
911 | ||
912 | * There are new typedefs `ushort' for `unsigned short int' and `uint' for | |
913 | `unsigned int' in <sys/types.h>. These are for compatibility only and | |
914 | their use is discouraged. | |
915 | ||
916 | * The `-lmcheck' library to enable standard malloc debugging hooks is now | |
917 | done differently, so that it works even without GNU ld. | |
787126fe | 918 | |
22a1292a RM |
919 | * New function `euidaccess' checks allowed access to a file like `access', |
920 | but using the effective IDs instead of the real IDs. | |
49e522bf RM |
921 | |
922 | * The time zone data files have been updated for the latest and greatest | |
923 | local time conventions of the countries of the world. | |
924 | ||
925 | * The new function `dirfd' extracts the file descriptor used by a DIR stream; | |
926 | see <dirent.h>. | |
927 | ||
928 | * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface | |
929 | for formatting floating-point numbers. They are provided only for | |
33a934a3 UD |
930 | compatibility; new programs should use `sprintf' instead. There are |
931 | also equivalent function for the `long double' floating-point type and | |
932 | all functions also exist in a reentrant form. | |
342414a6 RM |
933 | |
934 | * The new auxiliary library `-lutil' from 4.4 BSD contains various | |
935 | functions for maintaining the login-record files (primarily of use to | |
936 | system programs such as `login'), and convenient functions for | |
937 | allocating and initializing a pseudo-terminal (pty) device. | |
c709e372 RM |
938 | |
939 | * Ulrich Drepper has contributed new support for System V style | |
940 | shared memory and IPC on systems that support it. | |
941 | ||
942 | * Ulrich Drepper has contributed several miscellaneous new functions found | |
943 | in System V: The `hsearch' family of functions provide an effective | |
944 | implementation of hash tables; `a64l' and `l64a' provide a very simple | |
945 | binary to ASCII mapping; `drand48' and friends provide a 48-bit random | |
946 | number generator. | |
947 | ||
948 | * Ulrich Drepper has contributed new reentrant counterparts for the | |
949 | `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. | |
950 | ||
951 | * Ulrich Drepper has contributed new, highly-optimized versions of several | |
952 | string functions for the i486/Pentium family of processors. | |
953 | ||
71733723 | 954 | * Ulrich Drepper has updated the Linux-specific code, based largely |
c709e372 | 955 | on work done in Hongjiu Lu's version of GNU libc for Linux. |
33a934a3 UD |
956 | The GNU library now supports Linux versions 2.0.10 and later, |
957 | using the ELF object file format (i[3456]86-*-linux). | |
c709e372 | 958 | |
d3669add RM |
959 | * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). |
960 | ||
33a934a3 UD |
961 | * David Mosberger-Tang and Richard Henderson have ported the C library |
962 | to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the | |
963 | dynamic linking support for ELF/Alpha. | |
964 | ||
965 | * Richard Henderson contributed several Alpha optimized assembler function | |
966 | for arithmetic and string handling. | |
d3669add | 967 | |
c709e372 | 968 | * Ulrich Drepper has contributed a new set of message catalog functions to |
40a4b79f RM |
969 | support multiple languages using the <libintl.h> interface, for use with |
970 | his new package GNU gettext. Translation volunteers have contributed | |
971 | catalogs of the library's messages in Spanish, German, and Korean. | |
972 | ||
973 | * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' | |
974 | program and the `catgets' function for reading the catalog files it | |
975 | creates. (The <libintl.h> interface is preferred; we include the | |
976 | <nl_types.h> interface using `catgets' only for source compatibility with | |
977 | programs already written to use it.) | |
71733723 RM |
978 | |
979 | * New header file <values.h> gives SVID-compatible names for <limits.h> | |
980 | constants. | |
981 | ||
982 | * Various new macros, declarations, and small header files for compatibility | |
983 | with 4.4 BSD. | |
984 | ||
985 | * New function `group_member' is a convenient way to check if a process has | |
986 | a given effective group ID. | |
987 | ||
988 | * When using GCC 2.7 and later, the socket functions are now declared in a | |
989 | special way so that passing an argument of type `struct sockaddr_in *', | |
990 | `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic | |
991 | `struct sockaddr *' type, does not generate a type-clash warning. | |
992 | ||
993 | * New function `error' declared in header file <error.h> is a convenient | |
6d52618b | 994 | function for printing error messages and optionally exiting; this is the |
71733723 RM |
995 | canonical function used in GNU programs. The new functions `err', `warn', |
996 | and friends in header file <err.h> are the canonical 4.4 BSD interface for | |
997 | doing the same thing. | |
998 | ||
999 | * The <glob.h> interface has several new flags from 4.4 BSD that extend the | |
1000 | POSIX.2 `glob' function to do ~ and {...} expansion. | |
1001 | ||
1002 | * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. | |
33a934a3 | 1003 | `clearenv' which is used in POSIX.9 is also available. |
71733723 RM |
1004 | |
1005 | * New function `getsid' returns session ID number on systems that support it. | |
1006 | ||
f7eac6eb RM |
1007 | * We have incorporated the 4.4 BSD `db' library (version 1.85). New header |
1008 | files <db.h> and <mpool.h> provide a rich set of functions for several | |
1009 | types of simple databases stored in memory and in files, and <ndbm.h> is | |
6d52618b | 1010 | an old `ndbm'-compatible interface using the `db' functions. Link with |
999493cb | 1011 | `-ldb' to get these functions. |
f7eac6eb RM |
1012 | |
1013 | * New macro `strdupa' copies a string like `strdup', but uses local stack | |
1014 | space from `alloca' instead of dynamic heap space from `malloc'. | |
52e9a9d1 RM |
1015 | |
1016 | * New function `strnlen' is like `strlen' but searches only a given maximum | |
33a934a3 UD |
1017 | number of characters for the null terminator. `stpncpy', `strndup' and |
1018 | `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' | |
1019 | function. | |
40a4b79f RM |
1020 | |
1021 | * New function `statfs' in header <sys/statfs.h>. | |
1022 | ||
1023 | * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader | |
1024 | provide convenient functions for operating on blocks of null-terminated | |
1025 | strings. | |
1026 | ||
1027 | * A new suite of functions in <utmp.h> handle all the details of reading | |
1028 | and writing the utmp file. | |
33a934a3 UD |
1029 | |
1030 | * An implementation of the NIS/YP(tm) based NSS service was contributed by | |
1031 | Thorsten Kukuk. | |
1032 | ||
1033 | * Paul Eggert and Ulrich Drepper modified the `strftime' function to be | |
1034 | completely POSIX compliant and also implemented the extended functionality | |
1035 | to handle alternate digit representation and alternate era date formats. | |
1036 | ||
1037 | * Ulrich Drepper provided an implementation of the `strptime' function | |
1038 | defined in XPG4.2 which transforms a string into a `struct tm' value. | |
1039 | ||
1040 | * Paul Eggert provided the tzselect shell script as part of the timezone | |
1041 | code. The shell script makes it easy to select the correct timezone | |
1042 | specification. | |
1043 | ||
1044 | * The implementation of the malloc family of functions is completely replaced | |
1045 | by a new implementation by Doug Lea with many improvements by Wolfram Gloger. | |
1046 | The implementation uses the mmap function (if available) and it is | |
1047 | optimized for the use in multi threaded programs. | |
1048 | ||
1049 | * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of | |
1050 | functions. This new functionality is usable by specifying a special | |
1051 | salt string and it is compatible with implementation on *BSD systems. | |
1052 | ||
1053 | * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: | |
1054 | `getsubopt' to handle second level command line options, `bsd_signal' | |
1055 | to access BSD style `signal' functionality, the obsolete `regexp' style | |
1056 | expression matcher. | |
1057 | ||
1058 | * the `lchown' function is available on system which support this | |
1059 | functionality. | |
1060 | ||
1061 | * The implementation of the shadow password handling function was contributed | |
1062 | by Ulrich Drepper. | |
1063 | ||
1064 | * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. | |
1065 | ||
1066 | * POSIX.1g support was added. The <sys/select.h> header is available, | |
1067 | `isfdtype' and `pselect' are implemented. Craig Metz contributed an | |
1068 | implementation of `getaddrinfo'. | |
28f540f4 RM |
1069 | \f |
1070 | Version 1.09 | |
1071 | ||
1072 | * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. | |
1073 | ||
1074 | * New header file <fstab.h> and new functions `getfsspec', `getfsent' and | |
1075 | friends, for parsing /etc/fstab. This code comes from 4.4 BSD. | |
1076 | ||
1077 | * The new function `daemon' from 4.4 BSD is useful for server programs that | |
1078 | want to put themselves in the background. | |
1079 | ||
1080 | * Joel Sherrill has contributed support for several standalone boards that | |
1081 | run without an operating system. | |
1082 | ||
1083 | * `printf', `scanf' and friends now accept a `q' type modifier for long | |
1084 | long int as well as `ll'. Formats using these might be `%qu' or `%lld'. | |
1085 | ||
1086 | * All of the code taken from BSD (notably most of the math and networking | |
1087 | routines) has been updated from the BSD 4.4-Lite release. | |
1088 | ||
1089 | * The resolver code has been updated from the BIND-4.9.3-BETA9 release. | |
1090 | ||
1091 | * The new functions `getdomainname' and `setdomainname' fetch or change the | |
1092 | YP/NIS domain name. These are system calls which exist on systems which | |
1093 | have YP (aka NIS). | |
1094 | ||
1095 | * The time zone data files have been updated for the latest international | |
1096 | conventions. | |
1097 | ||
1098 | * The SunRPC programs `portmap' and `rpcinfo' are now installed in | |
1099 | $(sbindir) (usually /usr/local/sbin) instead of $(bindir). | |
1100 | \f | |
1101 | Version 1.08 | |
1102 | ||
1103 | * The C library now includes support for Sun RPC, from Sun's free | |
1104 | RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs | |
1105 | are included. (There is still no support for YP.) | |
1106 | ||
1107 | * Tom Quinn has contributed a port of the C library to SGI machines running | |
1108 | Irix 4 (mips-sgi-irix4). | |
1109 | ||
1110 | * The new `lockf' function is a simplified interface to the locking | |
1111 | facilities of `fcntl', included for compatibility. | |
1112 | ||
1113 | * New time functions `timegm', `timelocal', and `dysize' for compatibility. | |
1114 | ||
1115 | * New header file <sys/timeb.h> and new function `ftime' for compatibility. | |
1116 | ||
1117 | * New header files <poll.h> and <sys/poll.h> and new function `poll' for | |
1118 | compatibility. | |
1119 | ||
1120 | * The error message printed by `assert' for a failed assertion now includes | |
1121 | the name of the program (if using GNU ld) and the name of the calling | |
1122 | function (with versions of GCC that support this). | |
1123 | ||
1124 | * The `psignal' function is now declared in <signal.h>, not <stdio.h>. | |
1125 | ||
1126 | * The library now includes the <sys/mman.h> header file and memory | |
1127 | management functions `mmap', `munmap', `mprotect', `msync', and | |
1128 | `madvise', on systems that support those facilities. | |
1129 | ||
1130 | * The interface for `mcheck' has changed slightly: the function called to | |
1131 | abort the program when an allocation inconsistency is detected now takes | |
1132 | an argument that indicates the type of failure. The new function | |
1133 | `mprobe' lets you request a consistency check for a particular block at | |
1134 | any time (checks are normally done only when you call `free' or `realloc' | |
1135 | on a block). | |
1136 | ||
1137 | * It is now possible to easily cross-compile the C library, building on one | |
1138 | system a library to run on another machine and/or operating system. All | |
1139 | you need to do is set the variable `HOST_CC' in `configparms' to the | |
1140 | native compiler for programs to run on the machine you are building on (a | |
1141 | few generator programs are used on Unix systems); set `CC' to the | |
1142 | cross-compiler. | |
1143 | ||
1144 | * The new function `fexecve' (only implemented on the GNU system) executes | |
1145 | a program file given a file descriptor already open on the file. | |
1146 | \f | |
1147 | Version 1.07 | |
1148 | ||
1149 | * Brendan Kehoe has contributed most of a port to the DEC Alpha | |
1150 | running OSF/1 (alpha-dec-osf1). He says it is 75% complete. | |
1151 | ||
1152 | * You can set the variable `libprefix' in `configparms' to specify a prefix | |
1153 | to be prepended to installed library files; this makes it easy to install | |
1154 | the GNU C library to be linked as `-lgnuc' or whatever. | |
1155 | ||
1156 | * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It | |
1157 | copies a limited number of characters from a string, and returns the | |
1158 | address of the last character written. | |
1159 | ||
1160 | * You no longer need to check for whether the installed `stddef.h' is | |
1161 | compatible with the GNU C library. configure now checks for you. | |
1162 | ||
1163 | * You can now define a per-stream `fileno' function to convert the | |
1164 | stream's cookie into an integral file descriptor. | |
1165 | ||
1166 | * ``malloc (0)'' no longer returns a null pointer. Instead, it | |
1167 | allocates zero bytes of storage, and returns a unique pointer which | |
1168 | you can pass to `realloc' or `free'. The behavior is undefined if | |
1169 | you dereference this pointer. | |
1170 | ||
1171 | * The C library now runs on Sony NEWS m68k machines running either | |
1172 | NewsOS 3 or NewsOS 4. | |
1173 | ||
1174 | * The new `syscall' function is a system-dependent primitive function | |
1175 | for invoking system calls. It has the canonical behavior on Unix | |
1176 | systems, including unreliable return values for some calls (such as | |
1177 | `pipe', `fork' and `getppid'). | |
1178 | ||
1179 | * The error code `EWOULDBLOCK' is now obsolete; it is always defined | |
1180 | to `EAGAIN', which is the preferred name. On systems whose kernels | |
1181 | use two distinct codes, the C library now translates EWOULDBLOCK to | |
1182 | EAGAIN in every system call function. | |
1183 | \f | |
1184 | Version 1.06 | |
1185 | ||
1186 | * The GNU C Library Reference Manual is now distributed with the library. | |
1187 | `make dvi' will produce a DVI file of the printed manual. | |
1188 | `make info' will produce Info files that you can read on line using C-h i | |
1189 | in Emacs or the `info' program. | |
ea278354 | 1190 | Please send comments on the manual to bug-glibc-manual@gnu.org. |
28f540f4 RM |
1191 | |
1192 | * The library now supports SVR4 on i386s (i386-unknown-sysv4). | |
1193 | ||
1194 | * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. | |
1195 | ||
1196 | * Jason Merrill has contributed a port to the Sequent Symmetry running | |
1197 | Dynix version 3 (i386-sequent-dynix). | |
1198 | ||
1199 | * The library has been ported to i386s running SCO 3.2.4 (also known as SCO | |
1200 | ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). | |
1201 | ||
1202 | * New function `memory_warnings' lets you arrange to get warnings when | |
1203 | malloc is running out of memory to allocate, like Emacs gives you. | |
1204 | ||
1205 | * The C library now contains the relocating allocator used in Emacs 19 for | |
1206 | its editing buffers. This allocator (ralloc) minimizes allocation | |
1207 | overhead and fragmentation by moving allocated regions around whenever it | |
1208 | needs to. You always refer to a ralloc'd region with a "handle" (a | |
1209 | pointer to a pointer--an object of type `void **'). | |
1210 | ||
1211 | * There is a new `printf' format: `%m' gives you the string corresponding | |
1212 | to the error code in `errno'. | |
1213 | ||
1214 | * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' | |
1215 | or `%[' conversion, but instead of filling in a fixed-sized buffer you | |
1216 | pass, the `a' modifier says to fill in a `char **' you pass with a | |
1217 | malloc'd string. | |
1218 | ||
1219 | * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and | |
1220 | `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a | |
1221 | name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. | |
1222 | ||
1223 | * `mkstemp' is a traditional Unix function to atomically create and open a | |
1224 | uniquely-named temporary file. | |
1225 | \f | |
1226 | Version 1.05 | |
1227 | ||
1228 | * The standard location for the file that says what the local timezone is | |
1229 | has changed again. It is now `/usr/local/etc/localtime' (or more | |
1230 | precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. | |
1231 | ||
1232 | * The distribution no longer contains any files with names longer than 14 | |
1233 | characters. | |
1234 | ||
1235 | * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. | |
1236 | These are set by the new `trusted' and `console' keywords in `/etc/ttys'. | |
1237 | ||
1238 | * New functions `ttyslot' and `syslog' from 4.4 BSD. | |
1239 | \f | |
1240 | Version 1.04 | |
1241 | ||
1242 | * The configuration process has changed quite a bit. The `configure' | |
1243 | script is now used just like the configuration scripts for other GNU | |
1244 | packages. The `sysdeps' directory hierarchy is much rearranged. | |
1245 | The file `INSTALL' explains the new scheme in detail. | |
1246 | ||
1247 | * The header files no longer need to be processed into ANSI C and | |
1248 | traditional C versions. There is just one set of files to install, and | |
1249 | it will work with ANSI or old C compilers (including `gcc -traditional'). | |
1250 | ||
1251 | * Brendan Kehoe and Ian Lance Taylor have ported the library to the | |
1252 | MIPS DECStation running Ultrix 4. | |
1253 | ||
1254 | * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. | |
1255 | Tom Quinn contributed the initial code. The GNU C library can NOT yet be | |
1256 | made itself into a shared library. | |
1257 | ||
1258 | * Yet further improved support for the i386, running 4.3 BSD-like systems | |
1259 | (such as Mach 3 with the Unix single-server), or System V. | |
1260 | ||
1261 | * New function `strncasecmp' to do case-insensitive string comparison | |
1262 | with limited length. | |
1263 | ||
1264 | * New function `strsep' is a reentrant alternative to `strtok'. | |
1265 | ||
1266 | * New functions `scandir' and `alphasort' for searching directories. | |
1267 | ||
1268 | * New function `setenv' is a better interface to `putenv'. | |
1269 | ||
1270 | * Ian Lance Taylor has contributed an implementation of the SVID `ftw' | |
1271 | function for traversing a directory tree. | |
1272 | ||
1273 | * The GNU obstack package is now also part of the C library. | |
1274 | The new function `open_obstack_stream' creates a stdio stream that | |
1275 | writes onto an obstack; `obstack_printf' and `obstack_vprintf' do | |
1276 | formatted output directly to an obstack. | |
1277 | ||
1278 | * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), | |
1279 | cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. | |
1280 | ||
1281 | * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. | |
1282 | ||
1283 | * The new functions `strfry' and `memfrob' do mysterious and wonderful | |
1284 | things to your strings. | |
1285 | ||
1286 | * There are some new test programs: test-fseek, testmb, and testrand. | |
1287 | ||
1288 | * Some work has been done to begin porting the library to 4.4 BSD and Linux. | |
1289 | These ports are not finished, but are a good starting place for really | |
1290 | supporting those systems. | |
1291 | ||
1292 | * `/etc/localtime' is now the standard location for the file that says what | |
1293 | the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. | |
1294 | This follows the general principle that `/etc' is the place for all local | |
1295 | configuration files. | |
1296 | ||
1297 | * The C library header files now use `extern "C"' when used by the C++ | |
1298 | compiler, so the C library should now work with C++ code. | |
1299 | ||
1300 | * The header file <bstring.h> is gone. <string.h> now declares bcopy, | |
56ddf355 UD |
1301 | bcmp, bzero, and ffs. (Update: nowadays these functions are declared |
1302 | in <strings.h>.) | |
28f540f4 RM |
1303 | |
1304 | * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting | |
1305 | function which uses the `merge sort' algorithm, and is said to be | |
1306 | significantly faster than the old GNU `qsort' function. Merge sort is | |
1307 | now the standard `qsort' function. The new algorithm can require a lot | |
1308 | of temporary storage; so, the old sorting function is called when the | |
1309 | required storage is not available. | |
1310 | ||
1311 | * The C library now includes Michael Glad's Ultra Fast Crypt, which | |
1312 | provides the Unix `crypt' function, plus some other entry points. | |
28f540f4 RM |
1313 | |
1314 | * The code and header files taken from 4.4 BSD have been updated with the | |
1315 | latest files released from Berkeley. | |
