* Noteworthy changes in release 3.0.2 (2013-12-05) [stable]
** Bug fixes
*** Generated source files when errors are reported
When warnings are issued and -Werror is set, bison would still generate
the source files (*.c, *.h...). As a consequence, some runs of "make"
could fail the first time, but not the second (as the files were generated
anyway).
This is fixed: bison no longer generates this source files, but, of
course, still produces the various reports (*.output, *.xml, etc.).
*** %empty is used in reports
Empty right-hand sides are denoted by '%empty' in all the reports (text,
dot, XML and formats derived from it).
*** YYERROR and variants
When C++ variant support is enabled, an error triggered via YYERROR, but
not caught via error recovery, resulted in a double deletion.
* Noteworthy changes in release 3.0.1 (2013-11-12) [stable]
** Bug fixes
*** Errors in caret diagnostics
On some platforms, some errors could result in endless diagnostics.
*** Fixes of the -Werror option
Options such as "-Werror -Wno-error=foo" were still turning "foo"
diagnostics into errors instead of warnings. This is fixed.
Actually, for consistency with GCC, "-Wno-error=foo -Werror" now also
leaves "foo" diagnostics as warnings. Similarly, with "-Werror=foo
-Wno-error", "foo" diagnostics are now errors.
*** GLR Predicates
As demonstrated in the documentation, one can now leave spaces between
"%?" and its "{".
*** Installation
The yacc.1 man page is no longer installed if --disable-yacc was
specified.
*** Fixes in the test suite
Bugs and portability issues.
