Rockbox 4.0 released

For those of you who still have dedicated audio players: version 4.0 of
Rockbox, a replacement firmware for many players, has been released.
This release brings support for a number of new devices, updated codecs, a
number of user-interface improvements, some new games, and more. (LWN last
reviewed Rockbox in 2010 — and looked at
the ill-fated Android port that year as
well).
