-Changes in version 1.23:
+Changes in version 1.49a:

 
 

-The user can define YYPARSE_PARAM as the name of an argument to be passed
-   into yyparse.  The argument should have type void *.
-   It should actually point to an object.
-   Grammar actions can access the variable by casting it
-   to the proper pointer type.
+* Items overflow
+  Bison no longer dumps core when there are too many items, it just
+  dies.

 
 

-Error in printing reductions fixed.
+* Token end-of-file
+  The token end of file may be specified by the user, in which case,
+  the user symbol is used in the reports, the graphs, and the verbose
+  error messages instead of `$', which remains being the defaults.
+  For instance
+     %token YYEOF 0
+  or
+     %token YYEOF 0 "end of file"
+\f
+Changes in version 1.30:

 
 

-Line numbers in output file corrected.
+* `--defines' and `--graph' have now an optionnal argument which is the
+  output file name. `-d' and `-g' do not change, they do not take any
+  argument.

 
 

-Configuration and compilation problems fixed.
+* `%source_extension' and `%header_extension' are removed, failed
+  experiment.
+
+* Portability fixes.

-Changes in version 1.22:
+Changes in version 1.29, 2001-09-07:

 
 

---help option added.
+* The output file does not define const, as this caused problems when used
+  with common autoconfiguration schemes.  If you still use ancient compilers
+  that lack const, compile with the equivalent of the C compiler option
+  `-Dconst='.  autoconf's AC_C_CONST macro provides one way to do this.
+
+* Added `-g' and `--graph'.
+
+* The Bison manual is now distributed under the terms of the GNU FDL.
+
+* The input and the output files has automatically a similar extension.
+
+* Russian translation added.
+
+* NLS support updated; should hopefully be less troublesome.
+
+* Added the old Bison reference card.
+
+* Added `--locations' and `%locations'.
+
+* Added `-S' and `--skeleton'.
+
+* `%raw', `-r', `--raw' is disabled.
+
+* Special characters are escaped when output.  This solves the problems
+  of the #line lines with path names including backslashes.
+
+* New directives.
+  `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose',
+  `%debug', `%source_extension' and `%header_extension'.
+
+* @$
+  Automatic location tracking.
+\f
+Changes in version 1.28, 1999-07-06:
+
+* Should compile better now with K&R compilers.
+
+* Added NLS.
+
+* Fixed a problem with escaping the double quote character.
+
+* There is now a FAQ.
+\f
+Changes in version 1.27:
+
+* The make rule which prevented bison.simple from being created on
+  some systems has been fixed.
+\f
+Changes in version 1.26:
+
+* Bison now uses automake.
+
+* New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
+
+* Token numbers now start at 257 as previously documented, not 258.

 
 

-Configuration and compilation problems fixed.
+* Bison honors the TMPDIR environment variable.
+
+* A couple of buffer overruns have been fixed.
+
+* Problems when closing files should now be reported.
+
+* Generated parsers should now work even on operating systems which do
+  not provide alloca().

-Changes in version 1.21:
+Changes in version 1.25, 1995-10-16:
+
+* Errors in the input grammar are not fatal; Bison keeps reading
+the grammar file, and reports all the errors found in it.
+
+* Tokens can now be specified as multiple-character strings: for
+example, you could use "<=" for a token which looks like <=, instead
+of chosing a name like LESSEQ.
+
+* The %token_table declaration says to write a table of tokens (names
+and numbers) into the parser file.  The yylex function can use this
+table to recognize multiple-character string tokens, or for other
+purposes.

 
 

-Configuration and compilation problems fixed.
+* The %no_lines declaration says not to generate any #line preprocessor
+directives in the parser file.
+
+* The %raw declaration says to use internal Bison token numbers, not
+Yacc-compatible token numbers, when token names are defined as macros.
+
+* The --no-parser option produces the parser tables without including
+the parser engine; a project can now use its own parser engine.
+The actions go into a separate file called NAME.act, in the form of
+a switch statement body.

+Changes in version 1.23:

+passed into yyparse.  The argument should have type void *.  It should
+actually point to an object.  Grammar actions can access the variable
+by casting it to the proper pointer type.
