Speaking of fonts, I saw recently that due to the GPLv2 license tied to the
Liberation fonts, there has been some talk about moving away from them
because of the license's restrictions.
Instead, they may move to using Croscore fonts (Arimo, Tinos, Cousine) which
are not only metrically compatible with Liberation, but are improved versions
and are under an SIL license. There have also been talks about newer versions
of Liberation being based off of Croscore.
Pretty good breakdown here from a recent story on June 19, 2012:
