  * Fixes issue with GtkEntry causing applications to crash (LP: #1576424)

gtk+2.0 (2.24.31-1) unstable; urgency=medium

  * New upstream release.
  * Drop obsolete maintainer scripts which cleaned up the /usr/share/doc
    symlinks.
  * Refresh patches. Drop the ones which have been merged upstream.
  * When linking against libgail18, automatically generate a dependency on
    libgail-common. This was originally achieved via a .shlibs file but since
    we use a .symbols file nowadays, move this over there.
  * Remove an old shlibs.local hack which doesn't seem necessary anymore.
  * Use idiomatic variables from default.mk dpkg include.
    Bump Build-Depends on dpkg-dev to (>= 1.16.1).
