Downgrade
I was quite happy to notice, that my favourite VCS, Mercurial, was released in version 1.3.1! And I’m still using 1.1.2 out of the Ubuntu repository.
Eagerly I updated from the release PPA, but what did I know back than. First thing I noticed was the half done translation. German technical terms just suck.
More importantly they broke the zeroconf module. As most of my hg pulls are within my network, this is pretty serious for me. A fix is already committed, but not yet released. So back to 1.1.2 for me, as I like my VCS stable.
