-Changes in version 1.875a:
+Changes in version 1.875d:
+
+* Unescaped newlines are no longer allowed in character constants or
+ string literals. They were never portable, and GCC 3.4.0 has
+ dropped support for them. Better diagnostics are now generated if
+ forget a closing quote.
+
+* NUL bytes are no longer allowed in Bison string literals, unfortunately.
+
+* %token numbers can now be hexadecimal integers, e.g., `%token FOO 0x12d'.
+ This is a GNU extension.
+
+* A new directive "%expect-rr N" specifies the expected number of
+ reduce/reduce conflicts in GLR parsers.
+
+* Experimental %destructor support has been added to lalr1.cc.
+
+Changes in version 1.875c, 2003-08-25:
+
+ (Just bug fixes.)
+
+Changes in version 1.875b, 2003-06-17:
+
+* GLR grammars now support locations.
+
+* Semicolon changes:
+ - Semicolons are now allowed before "|" in grammar rules, as POSIX requires.
+ - Stray semicolons are no longer allowed at the start of a grammar.
+ - Semicolons are now required after in-grammar declarations.
+
+Changes in version 1.875a, 2003-02-01:
+
+* For now, %expect-count violations are now just warnings, not errors.
+ This is for compatibility with Bison 1.75 and earlier (when there are
+ reduce/reduce conflicts) and with Bison 1.30 and earlier (when there
+ are too many or too few shift/reduce conflicts). However, in future
+ versions of Bison we plan to improve the %expect machinery so that
+ these violations will become errors again.
* New configure option --disable-yacc, to disable installation of the
yacc command and -ly library introduced in 1.875 for POSIX conformance.
