Last week, the CyanogenMod team launched the first CM9 nightly builds for the Galaxy Nexus, Nexus S, and Motorola XOOM. As of today, the following devices also have CM9 nightly builds available:

Samsung Galaxy Tab 10.1 Wi-Fi and I/O Edition ( download : p4wifi) - yay for the latter, as it seems Samsung completely abandoned it - I believe mine is still running 3.1 with no updates in sight.

Update: It looks like the Tab 10.1 builds aren't nightlies just yet but rather available as snapshots, which presumably means one-time builds on the dates listed.

Definition: A "nightly" is a bleeding edge release that is built on a daily basis, usually at night after a full day's worth of new code has been committed. : A "nightly" is a bleeding edge release that is built on a daily basis, usually at night after a full day's worth of new code has been committed. It could oftentimes be unstable and not properly tested, lacking any changelogs, but eventually evolving into alphas, betas, release candidates, and finally stable releases.

If you have one of the above devices, welcome to the nightly club, folks - download, flash away, and report back with any problems.

Hopefully, the rate at which nightly support is added to other devices improves sharply once all the servers from the recent donation drive are in place and fully chugging along. You bet we'll be here to tell you.
