+Changes in version 1.875e, 2004-12-10:
+
+* New directive: %initial-action.
+  This directive allows the user to run arbitrary code (including
+  initializing @$) from yyparse before parsing starts.
+
+* The option `--report=lookahead' was changed to `--report=look-ahead'.
+  The old spelling still works, but is not documented and will be
+  removed.
+
+* Error token location.
+  During error recovery, the location of the syntax error is updated
+  to cover the whole sequence covered by the error token: it includes
+  the shifted symbols thrown away during the first part of the error
+  recovery, and the lookahead rejected during the second part.
+
+* Goto numbers are no longer arbitrarily limited to 16-bit counts.
+
+Changes in version 1.875d, 2004-05-21:
+
+* 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.
