NEWS:
Changes in version 1.30b:

* Fixed parser memory leaks.
  When the generated parser was using malloc to extend its stacks, the
  previous allocations were not freed.

* Fixed verbose output file.
  Some newlines were missing.
  Some conflicts in state descriptions were missing.

* Fixed conflict report.
  Option -v was needed to get the result.

* %expect
  Was not used.
  Mismatches are errors, not warnings.

* Fixed incorrect processing of some invalid input.

* Fixed CPP guards: 9foo.h uses BISON_9FOO_H instead of 9FOO_H.

* Fixed some typos in the documentation.

* %token MY_EOF 0 is supported.
  Before, MY_EOF was silently renumbered as 257.

* doc/refcard.tex is updated.

* %output, %file-prefix, %name-prefix.
  New.

* --output
  New, aliasing `--output-file'.
