  • Revision ID: james.westby@ubuntu.com-20100525095014-6mlrm9z9bkws0zkt
Tags: 4:4.4.80-0ubuntu1
* New upstream beta release:
  - Bump kde-sc-dev-latest build-dep version to 4.4.80
  - Refresh kubuntu_04_kimpanel_disable_scim.diff
  - Update various .install files
  - Drop liblancelot0a and liblancelot-dev packages; Upstream has broken ABI
    without an .so version bump, and after discussion with Debian it was
    decided it was not worth it to ship an unstable library.
  - Add liblancelot files to plasma-widget-lancelot, adding appropriate
    Replaces: entries
* Switch to source format 3.0 (quilt):
  - Bump debhelper build-depend version to 7.3.16 or greater
