metacity (1:2.34.3-3) unstable; urgency=low

  [ Josselin Mouette ]
  * 01_focus_new_window.patch: new patch from upstream bugzilla.
    Correctly focus new windows even when they appear behind an ?^?^?always

  [ Michael Biebl ]
  * Rebuild with xz compression for binary packages.

metacity (1:2.34.3-2) unstable; urgency=low

  * Upload to unstable.
  * Replace Suggests: gnome-themes with Recommends: gnome-themes-standard
    since Adwaita is the preferred window manager theme and we want it to be
    installed by default.
  * Use strict dependency between metacity/libmetacity-private0a and
    metacity-common to ensure we have the correct version of metacity-common
    providing the org.gnome.metacity gsettings schema.

metacity (1:2.34.3-1) experimental; urgency=low

  * New upstream release.
  * Bump Build-Depends on libgtk2.0-dev to (>= 2.24.0) and libglib2.0-dev to

    (>= 3.3.0).

  [ Michael Biebl ]
  * Use a strict dependency between metacity and libmetacity-private.
  * Due to incompatible changes in libmetacity-private, which broke reverse
    dependencies like compiz, rename the library package to
    libmetacity-private0a. Closes: #629310
  * Add Breaks/Replaces: libmetacity-private0 to libmetacity-private0a.
  * Add a lintian override for the package-name-doesnt-match-sonames warning.
  * debian/watch: Track .xz tarballs.
