+* Changes in version 2.5.1_rc1 (2012-05-14):

 
 

-** Named References Support
+** Future changes:
+
+  The next major release will drop support for generating parsers in
+  K&R C.
+
+** yacc.c: YYBACKUP works as expected.
+
+** glr.c improvements:
+
+*** Location support is eliminated when not requested:
+
+  GLR parsers used to include location-related code even when
+  locations were not requested, and therefore not even usable.
+
+*** __attribute__ is preserved:
+
+  __attribute__ is no longer disabled when __STRICT_ANSI__ is defined
+  (i.e., when -std is passed to GCC).
+
+** lalr1.java: several fixes:
+
+  The Java parser no longer throws ArrayIndexOutOfBoundsException if
+  the first token leads to a syntax error.  Some minor clean ups.
+
+** C++11 compatibility:
+
+  C and C++ parsers use nullptr instead of 0 when __cplusplus is
+  201103L or higher.
+
+** C++ locations:
+
+  The position and location constructors (and their initialize
+  methods) accept new arguments for line and column.  Several issues
+  in the documentation were fixed.
+
+** liby is no longer asking for "rpl_fprintf" on some platforms.
+
+** Changes in the manual:
+
+*** %printer is documented
+
+  The %printer directive, supported since at least Bison 1.50, is
+  finally documented.  The %mfcalc example is extended to demonstrate
+  its use of printer.
+
+  The C++ parsers now also support yyoutput (as an alias to
+  debug_stream ()) for consistency with the C skeletons.
+
+*** Several improvements have been made:
+
+  The layout for grammar excerpts was changed to a more compact
+  scheme.  Named references are motivated.  The description of the
+  automaton description file (*.output) is updated to the current
+  format.  Incorrect index entries were fixed.  Some other errors were
+  fixed.
+
+** Building bison:
+
+*** Conflicting prototypes with recent/modified Flex.
+
+  Fixed build problems with the current, unreleased, version of Flex,
+  and some modified versions of 2.5.35, which have modified function
+  prototypes.
+
+*** Warnings during the build procedure have been eliminated.
+
+*** Several portability problems in the test suite have been fixed:
+
+  This includes warnings with some compilers, unexpected behavior of
+  tools such as diff, warning messages from the test suite itself,
+  etc.
+
+*** The install-pdf target work properly:
+
+  Running "make install-pdf" (or -dvi, -html, -info, and -ps) no
+  longer halts in the middle of its course.
+
+* Changes in version 2.5 (2011-05-14):
+
+** Grammar symbol names can now contain non-initial dashes:
+
+  Consistently with directives (such as %error-verbose) and with
+  %define variables (e.g. push-pull), grammar symbol names may contain
+  dashes in any position except the beginning.  This is a GNU
+  extension over POSIX Yacc.  Thus, use of this extension is reported
+  by -Wyacc and rejected in Yacc mode (--yacc).

-** Unrecognized %code qualifiers are now an error not a warning.
+** LAC (Lookahead Correction) for syntax error handling:

 
 

-** %define improvements.
+  Canonical LR, IELR, and LALR can suffer from a couple of problems
+  upon encountering a syntax error.  First, the parser might perform
+  additional parser stack reductions before discovering the syntax
+  error.  Such reductions can perform user semantic actions that are
+  unexpected because they are based on an invalid token, and they
+  cause error recovery to begin in a different syntactic context than
+  the one in which the invalid token was encountered.  Second, when
+  verbose error messages are enabled (with %error-verbose or the
+  obsolete `#define YYERROR_VERBOSE'), the expected token list in the
+  syntax error message can both contain invalid tokens and omit valid
+  tokens.

 
 

-*** Unrecognized variables are now an error not a warning.
+  The culprits for the above problems are %nonassoc, default
+  reductions in inconsistent states, and parser state merging.  Thus,
+  IELR and LALR suffer the most.  Canonical LR can suffer only if
+  %nonassoc is used or if default reductions are enabled for
+  inconsistent states.

 
 

-*** Multiple invocations for any variable is now an error not a warning.
+  LAC is a new mechanism within the parsing algorithm that solves
+  these problems for canonical LR, IELR, and LALR without sacrificing
+  %nonassoc, default reductions, or state merging.  When LAC is in
+  use, canonical LR and IELR behave almost exactly the same for both
+  syntactically acceptable and syntactically unacceptable input.
+  While LALR still does not support the full language-recognition
+  power of canonical LR and IELR, LAC at least enables LALR's syntax
+  error handling to correctly reflect LALR's language-recognition
+  power.
+
+  Currently, LAC is only supported for deterministic parsers in C.
+  You can enable LAC with the following directive:
+
+    %define parse.lac full

 
 

-*** Can now be invoked via the command line.

+*** Bison now properly recognizes the `no-' versions of categories:

 
 

-** YYLLOC_DEFAULT in C++
+  For example, given the following command line, Bison now enables all
+  warnings except warnings for incompatibilities with POSIX Yacc:

 
 

-  The default implementation of YYLLOC_DEFAULT used to be issued in
-  the header file.  It is now output in the implementation file, after
-  the user %code sections so that its #ifndef guard does not try to
-  override the user's YYLLOC_DEFAULT if provided.
+    bison -Wall,no-yacc gram.y
+
+*** Bison now treats S/R and R/R conflicts like other warnings:
+
+  Previously, conflict reports were independent of Bison's normal
+  warning system.  Now, Bison recognizes the warning categories
+  `conflicts-sr' and `conflicts-rr'.  This change has important
+  consequences for the -W and --warnings command-line options.  For
+  example:
+
+    bison -Wno-conflicts-sr gram.y  # S/R conflicts not reported
+    bison -Wno-conflicts-rr gram.y  # R/R conflicts not reported
+    bison -Wnone            gram.y  # no conflicts are reported
+    bison -Werror           gram.y  # any conflict is an error
+
+  However, as before, if the %expect or %expect-rr directive is
+  specified, an unexpected number of conflicts is an error, and an
+  expected number of conflicts is not reported, so -W and --warning
+  then have no effect on the conflict report.
+
+*** The `none' category no longer disables a preceding `error':
+
+  For example, for the following command line, Bison now reports
+  errors instead of warnings for incompatibilities with POSIX Yacc:
+
+    bison -Werror,none,yacc gram.y
+
+*** The `none' category now disables all Bison warnings:
+
+  Previously, the `none' category disabled only Bison warnings for
+  which there existed a specific -W/--warning category.  However,
+  given the following command line, Bison is now guaranteed to
+  suppress all warnings:
+
+    bison -Wnone gram.y
+
+** Precedence directives can now assign token number 0:
+
+  Since Bison 2.3b, which restored the ability of precedence
+  directives to assign token numbers, doing so for token number 0 has
+  produced an assertion failure.  For example:
+
+    %left END 0
+
+  This bug has been fixed.
