@@@ -69,24 -96,24 +96,38 @@@ New in 1.11.0a
      the `${infodir}/dir' file, by exporting the new environment variable
      `AM_UPDATE_INFO_DIR' to the value "no".
  
+   - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
+     and adds them to the normal list of dependencies, but without
+     overwriting the foo_DEPENDENCIES variable, which is normally computed
+     by automake.
+ 
 +* Changes to Yacc support:
 +
 +  - C source and header files derived from non-distributed Yacc and/or
 +    Lex sources are now removed by a simple "make clean" (while they were
 +    previously removed only "make maintainer-clean").
 +
 +  - Slightly backward-incompatible change, relevant only for use of Yacc
 +    with C++: the extensions of the header files produced by the Yacc
 +    rules are now modelled after extension of the sources corresponding
 +    sources.  For example, yacc files named "foo.y++" and "bar.yy" will
 +    produce header files named respectively "foo.h++" and "bar.hh", where
 +    they would have previously produced header files named simply "foo.h"
 +    and "bar.h".  This change offers better compatibility with `bison -o'.
 +
  Bugs fixed in 1.11.0a:
  
+ * Bugs introduced by 1.11.2:
+ 
+   - Automake now correctly recognizes the prefix/primary combination
+    `pkglibexec_SCRIPTS' as valid.
+ 
  * Bugs introduced by 1.11:
  
+   - The parallel-tests harness doesn't trip anymore on sed implementations
+     with stricter limits on the length of input lines (problem seen at
+     least on Solaris 8).
+ 
    - The `parallel-tests' test driver works around a GNU make 3.80 bug with
      trailing white space in the test list (`TESTS = foo $(EMPTY)'), and
      does not report spurious successes when used with concurrent FreeBSD
