Rockbox 4.0 released!

[speachy]

The Rockbox project is pleased to announce the immediate availability of
Rockbox 4.0. This marks our first release since November 2019, and since
then we've been busy adding features and fixing bugs to give you the
best Rockbox experience yet.

The list of changes is too extensive to summarize here, but the full
release notes may be found here:

For most of Rockbox's "stable" devices, the Rockbox Utility can be used
to automatically handle installation, updates, and more:

If you wish to perform the installation or update manually, binaries
for all "stable" targets are indexed here:

All others will need to be manually downloaded from here:

Enjoy Rockbox - we enjoy making it.
