CyanogenMod is probably the most popular AOSP-based custom ROM out there. Overnight, the wizards behind this ROM released v7.1 Release Candidate 1 of their wares. The changelog for this release is fairly massive, and quite impressive as well. Probably the biggest change is an upgrade to Android version 2.3.4 (from 2.3.3 in v7.0). They are now also supporting Bluetooth mice, a wake on volume key option, and support for launching apps via gestures. We've got the full changelog after the break.
If you're interested in taking this new release for a spin, just download it via ROM Manager, or hit up the source link after the break. If you download it via the source link, don't forget to grab an updated copy of GAPPS (the Google apps, such as the Market, etc.).
