i3/RELEASE-NOTES-4.9

 ┌──────────────────────────────┐
 │ Release notes for i3 v4.9    │
 └──────────────────────────────┘

This is i3 v4.9. This version is considered stable. All users of i3 are
strongly encouraged to upgrade.

Notable new features include mouse button bindings and improved EWMH
compatibility, meaning more external pager programs work with i3 now.

Aside from that, this release contains plenty of bugfixes and little
enhancements.

The new dependency on libxkbcommon ≥ 0.4.0 is notable for distribution
packages. This dependency allowed us to drop our last direct dependency
on Xlib :).

It’s also worth mentioning that all i3 repositories are now on GitHub, see
http://thread.gmane.org/gmane.comp.window-managers.i3.general/1666 for the
announcement.
