14 DAY TRIAL // The final touches for the release of Ubuntu 14.04 (Trusty Tahr) are now being taken care of and the developers are discussing the removal of the gstreamer 0.10 packages from the Trusty CD.
The gstreamer 0.10 library has been in use for a very long time and many developers built their applications with dependencies for this library. Fortunately, a new version has been released for quite a while, but the old library still lingers around, even at this time.
A developer has pushed for the removal of gstreamer 0.10 from the Trusty desktop CD, but there are a couple of applications that still depend on it, like Pidgin (through libpurple) and Bluez 5.0.
“For some reason I thought we had already removed 0.10 from the trusty desktop cd. Also Ubuntu-sso-client and related would need to ported to qt5 I guess to remove the dependency that qt4 brings in? I'm guessing this is too much to try doing in trusty (especially now), but we would be looking at saving ~60 Mb of compressed space if we could do this,” said Bryan Quigley on the official mailing list.
Ubuntu 14.04 (Trusty Tahr) is expected to arrive on April 17, so it's likely that more of these fixes are incoming.
