Some serious, and old, bugs have been fixed.

Here are the compressed sources:

Here are the GPG detached signatures[*]:

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify bison-2.6.2.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys 0DDCAA3278D5264E

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69
  Automake 1.12.2
  Flex 2.5.36
  Gettext 0.18.1
  Gnulib v0.0-7558-gbd54a45

NEWS

* Noteworthy changes in release 2.6.2 (2012-08-03) [stable]

** Bug fixes

  Buffer overruns, complaints from Flex, and portability issues in the test
  suite have been fixed.

** Spaces in %lex- and %parse-param (lalr1.cc, glr.cc)

  Trailing end-of-lines in %parse-param or %lex-param would result in
  invalid C++.  This is fixed.

** Spurious spaces and end-of-lines

  The generated files no longer end (nor start) with empty lines.

* Noteworthy changes in release 2.6.1 (2012-07-30) [stable]

 Bison no longer executes user-specified M4 code when processing a grammar.

** Future Changes

  In addition to the removal of the features announced in Bison 2.6, the
  next major release will remove the "Temporary hack for adding a semicolon
  to the user action", as announced in the release 2.5.  Instead of:

    exp: exp "+" exp { $$ = $1 + $3 };

  write:

    exp: exp "+" exp { $$ = $1 + $3; };

** Bug fixes

*** Type names are now properly escaped.

*** glr.cc: set_debug_level and debug_level work as expected.

*** Stray @ or $ in actions

  While Bison used to warn about stray $ or @ in action rules, it did not
  for other actions such as printers, destructors, or initial actions.  It
  now does.

** Type names in actions

  For consistency with rule actions, it is now possible to qualify $$ by a
  type-name in destructors, printers, and initial actions.  For instance:

    %printer { fprintf (yyo, "(%d, %f)", $<ival>$, $<fval>$); } <*> <>;

  will display two values for each typed and untyped symbol (provided
  that YYSTYPE has both "ival" and "fval" fields).
