+Snapshot 20030715 (15 July 2003)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+20030715 is a snapshot of our current CVS head (development) branch.
+This is the branch which will become valgrind-2.0.  It contains
+significant enhancements over the 1.9.X branch.
+
+Despite this being a snapshot of the CVS head, it is believed to be
+quite stable -- at least as stable as 1.9.6 or 1.0.4, if not more so
+-- and therefore suitable for widespread use.  Please let us know asap
+if it causes problems for you.
+
+Two reasons for releasing a snapshot now are:
+
+- It's been a while since 1.9.6, and this snapshot fixes
+  various problems that 1.9.6 has with threaded programs 
+  on glibc-2.3.X based systems.
+
+- So as to make available improvements in the 2.0 line.
+
+Major changes in 20030715, as compared to 1.9.6:
+
+- More fixes to threading support on glibc-2.3.1 and 2.3.2-based
+  systems (SuSE 8.2, Red Hat 9).  If you have had problems
+  with inconsistent/illogical behaviour of errno, h_errno or the DNS
+  resolver functions in threaded programs, 20030715 should improve
+  matters.  This snapshot seems stable enough to run OpenOffice.org
+  1.1rc on Red Hat 7.3, SuSE 8.2 and Red Hat 9, and that's a big
+  threaded app if ever I saw one.
+
+- Automatic generation of suppression records; you no longer
+  need to write them by hand.  Use --gen-suppressions=yes.
+
+- The GDB attach mechanism is more flexible.  Allow the GDB to
+  be run to be specified by --gdb-path=/path/to/gdb, and specify
+  which file descriptor V will read its input from with
+  --input-fd=<number>.
+
+- Complete support for the MMX instruction set.
+
+- Partial support for the SSE and SSE2 instruction sets.  Work for this
+  is ongoing.  About half the SSE/SSE2 instructions are done, so
+  some SSE based programs may work.  Currently you need to specify
+  --skin=addrcheck.  Basically not suitable for real use yet.
+
+- Significant speedups (10%-20%) for standard memory checking.
+
+- Fix assertion failure in pthread_once().
+
+- Fix this:
+    valgrind: vg_intercept.c:598 (vgAllRoadsLeadToRome_select): 
+              Assertion `ms_end >= ms_now' failed.
+
+- Implement pthread_mutexattr_setpshared.
+
+- Understand Pentium 4 branch hints.  Also implemented a couple more
+  obscure x86 instructions.
+
+- Lots of other minor bug fixes.
+
+As ever, thanks for the vast amount of feedback :) and bug reports :(
+We may not answer all messages, but we do at least look at all of
+them, and tend to fix the most frequently reported bugs.
+

 Version 1.9.6 (7 May 2003 or thereabouts)
