+Changes in version 1.875e:
+
+* 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.
+
+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.)
