[ Sebastien Bacher ]
* New upstream version
* debian/control.in: recommends libcanberra-pulse (lp: #1004973)
* debian/patches/58_ubuntu_icon_views_redesign.patch:
  - drop most of the changes, keep the different grid size though
    to fit on screen with our extra icons
* debian/patches/91_dont_show_in_unity.patch:
  - dropped, show the upstream printer panel and the layout tab
* debian/patches/revert_git_keyboard_gsettings.patch,
  debian/patches/revert_git_stop_using_gconf.patch:
  - dropped the gconf->gsettings reverts

[ Robert Ancell ]
* New upstream release (LP: #1010317)
* debian/control:
  - Bump build-depends on libgnome-desktop-3-dev, libwacom-dev
  - Add build-depends on libclutter-1.0-dev, libclutter-gtk-1.0-dev,
    libpwquality-dev
  - Drop build-depends on libgnomekbd-dev
* debian/patches/60_ubuntu_nav_bar.patch:
  - Disabled for now, doesn't apply
* debian/patches/revert_ua_gsettings.patch:
  - We can use GSettings for universal access now
* debian/patches/00git_online_accounts_gtkgrid.patch:
* debian/patches/00git_online_accounts_layout.part:
* debian/patches/git_wacom_translations.patch:
  - Applied upstream

[ Iain Lane ]
* Add Build-Depends on libxkbfile-dev
* New upstream release.
* Refresh all patches to apply cleanly.

[ Edward Donovan ]
* debian/source_gnome-control-center.py: Fix for Python 3. (LP: #1013171)

[ Rico Tzschichholz ]
* debian/control.in:
  - Build-depend on gtk-doc-tools instead of docbook directly
  - Bump minimum glib-2.0, gnome-desktop3, gnome-settings-daemon
     and gsettings-desktop-schemas

[ Jeremy Bicha ]
* Dropped more patches applied in new version:
  - git_unmute_sound_event.patch
  - git_fix_big_editable_labels.patch
  - 96_sound_nua_panel.patch

* debian/patches/52_ubuntu_language_list_mods.patch:
  - Don't disable adding current language to the list. While this

    "Ubuntu suddenly in Chinese" bug (LP: #1035219)
* debian/patches/53_use_ubuntu_help.patch:
  - Only show Ubuntu help when running Unity
* debian/patches/58_hide_gdm_notifications.patch:
  - Hide "Show notifications when locked" settings when running Unity
    since it's a GNOME Shell-specific feature
* debian/patches/63_normal_scrollbar_in_a11y.patch:
  - Drop, overlay-scrollbars should handle this instead
* debian/patches/91_dont_show_in_unity.patch:
  - Hide Printers & Region panels in Unity until we're ready to switch
    to them.
* debian/patches/fix-crash-on-user-panel.patch:
  - Dropped, GNOME says it's obsolete
* debian/rules:
  - Build with -z,defs again
  - Explicitly disable ibus support since ibus 1.4 isn't supported in
    this version
* debian/control.in:
  - Drop ubuntu-docs and gnome-user-guide from recommends to suggests
  - Don't recommend indicators; let's leave that to Unity

[ David Henningsson ]
* sound_nua_panel.patch: Rebase to gnome 3.6
