	2	----------
	3
	4	Changes in version 1.29e:
	5
	6	* `--defines' and `--graph' have now an optionnal argument which is the
	7	output file name. `-d' and `-g' do not change, they do not take any
	8	argument.
	9
	10	* `%source_extension' and `%header_extension' are removed, failed
	11	experiment.
	12
	13	* The test suite is more portable.
	14
	15	* Better portability.
	16
	17	Changes in version 1.29:
	18
	19	* The output file does not define const, as this caused problems when used
	20	with common autoconfiguration schemes. If you still use ancient compilers
	21	that lack const, compile with the equivalent of the C compiler option
	22	`-Dconst='. autoconf's AC_C_CONST macro provides one way to do this.
	23
	24	* Added `-g' and `--graph'.
	25
	26	* The Bison manual is now distributed under the terms of the GNU FDL.
	27
	28	* The input and the output files has automatically a similar extension.
	29
	30	* Russian translation added.
	31
	32	* NLS support updated; should hopefully be less troublesome.
	33
	34	* Added the old Bison reference card.
	35
	36	* Added `--locations' and `%locations'.
	37
	38	* Added `-S' and `--skeleton'.
	39
	40	* `%raw', `-r', `--raw' is disabled.
	41
	42	* Special characters are escaped when output. This solves the problems
	43	of the #line lines with path names including backslashes.
	44
	45	* New directives.
	46	`%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose',
	47	`%debug', `%source_extension' and `%header_extension'.
	48	\f
	49	Changes in version 1.28:
	50
	51	* Should compile better now with K&R compilers.
	52
	53	* Added NLS.
	54
	55	* Fixed a problem with escaping the double quote character.
	56
	57	* There is now a FAQ.
	58	\f
	59	Changes in version 1.27:
	60
	61	* The make rule which prevented bison.simple from being created on
	62	some systems has been fixed.
	63	\f
	64	Changes in version 1.26:
	65
	66	* Bison now uses automake.
	67
	68	* New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
	69
	70	* Token numbers now start at 257 as previously documented, not 258.
	71
	72	* Bison honors the TMPDIR environment variable.
	73
	74	* A couple of buffer overruns have been fixed.
	75
	76	* Problems when closing files should now be reported.
	77
	78	* Generated parsers should now work even on operating systems which do
	79	not provide alloca().
	80	\f
	81	Changes in version 1.25:
	82
	83	* Errors in the input grammar are not fatal; Bison keeps reading
	84	the grammar file, and reports all the errors found in it.
	85
	86	* Tokens can now be specified as multiple-character strings: for
	87	example, you could use "<=" for a token which looks like <=, instead
	88	of chosing a name like LESSEQ.
	89
	90	* The %token_table declaration says to write a table of tokens (names
	91	and numbers) into the parser file. The yylex function can use this
	92	table to recognize multiple-character string tokens, or for other
	93	purposes.
	94
	95	* The %no_lines declaration says not to generate any #line preprocessor
	96	directives in the parser file.
	97
	98	* The %raw declaration says to use internal Bison token numbers, not
	99	Yacc-compatible token numbers, when token names are defined as macros.
	100
	101	* The --no-parser option produces the parser tables without including
	102	the parser engine; a project can now use its own parser engine.
	103	The actions go into a separate file called NAME.act, in the form of
	104	a switch statement body.
	105	\f
	106	Changes in version 1.23:
	107
	108	The user can define YYPARSE_PARAM as the name of an argument to be
	109	passed into yyparse. The argument should have type void *. It should
	110	actually point to an object. Grammar actions can access the variable
	111	by casting it to the proper pointer type.
	112
	113	Line numbers in output file corrected.
	114	\f
	115	Changes in version 1.22:
	116
	117	--help option added.
	118	\f
	119	Changes in version 1.20:
	120
	121	Output file does not redefine const for C++.
