---------------
hud (13.10.1+14.04.20131029.1-0ubuntu1) trusty; urgency=low
[ Pete Woods ]
* Fix the ref counting of application sources The application sources
are now entirely owned by the application-list's hash table.
[ Ted Gould ]
* Add apport dependencies to the package hook. (LP: #1233994)
* Don't show disabled items in search results. (LP: #1192646)
[ Charles Kerr ]
* Add a nullptr safeguard to prevent a crash-on-null-ptr-reference.
Also, move a QMap lookup outside of a for loop. Yay! . (LP:
#1242032)
* if we can't get the busname, log a g_critical and then exit
gracefully instead of abort()ing in g_error. (LP: #1244688)
* Add a null safeguard when accessing window SharedPtrs held in the
m_windows QMap . (LP: #1243654)
[ Ubuntu daily release ]
* Automatic snapshot from revision 343
