“As part of Ubuntu’s stance of providing the best of open
source/free software by default, the mail client Evolution has been
switched to Mozilla’s Thunderbird. This has meant that there has
been a concerted effort for better desktop integration with
Thunderbird, which many prior users have been wanting for some
time. This is similar to the change we saw last cycle with the
switch from Rhythmbox to Banshee media player. Whilst the original
applications are still available in Software Centre, they are
no-longer installed by default.“Synaptic, the former default desktop package manager which has
traditionally been dual default along with Ubuntu Software Centre
has now also been dropped, the rational being that the replacement
has now reached a level of maturity meaning that Synaptic has also
been dropped as installed by default. However, this can be
installed if the user desires. The Software Centre itself has
undergone a makeover, which is currently in trunk; but was not part
of the Alpha 3 release and possibly not the default for final
Oneiric release.”
