- to the proper pointer type.
+* Russian translation added.

+Changes in version 1.28:
---help option added.
+* Should compile better now with K&R compilers.
+
+* Added NLS.
+
+* Fixed a problem with escaping the double quote character.
+
+* There is now a FAQ.

+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.
+
+* Bison honors the TMPDIR environment variable.
+
+* A couple of buffer overruns have been fixed.
-Configuration and compilation problems fixed.
+* Problems when closing files should now be reported.
+
+* Generated parsers should now work even on operating systems which do
+ not provide alloca().
+\f
+Changes in version 1.25:
+
+* 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.
+
+* 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.
