[ Barry Warsaw ] * New upstream release. - LP: #1284217 - When CheckForUpdate() is called a second time, while an auto-download is in progress, but after the first check is complete, we send an UpdateAvailableStatus signal with the cached information. - LP: #1287919 - Close a race condition when manually downloading and issuing multiple CheckForUpdate calls. - LP: #1278589 - Support disabling either HTTP or HTTPS services for custom system image servers. - Allow the channel.ini file to override the [service] section. - LP: #1287287 - Do not do atomic renames of temporary download files; ubuntu-download-manager now supports this by default. - LP: #1250817 - Exceptions in the state machine are caught and logged, with an appropriate error message added to UpdateAvailableStatus signals. These exceptions do not percolate up to the GLib main loop. - LP: #1279532 - During testing, pass the log dir argument to ubuntu-download-manager. * d/rules: Add override_dh_python3 rule to set shebang line to /usr/bin/python3. (LP: #1283277) * d/patches/lp1284217.patch: Removed; applied upstream.
