The CyanogenMod team has started rolling out the fourth milestone build of CM11, based on Android 4.4.2 KitKat. The latest release mainly contains a lot of low-levels tweaks and changes along with quite a few bug-fixes. 

Some notable changes in this milestone build include a left-hand mode for the navigation bar, transparent volume panel and quicker boot up times on multi-core devices. Being a milestone release, it should be more stable than nightly builds for your device. You can flash the latest milestone on top of the previous M or stable CM11 release without any issues as well.

The official change-log from the CM team is below:

• Immersive Mode – prevent accidental clicks on swipe gesture (EdgeGesture service)
• Bluetooth LE – Wipower SDK apis, various fixes
• System NavBar – Left Hand mode (landscape only – not available on tablets)
• Motion Accelerometer support (device dependant)
• Volume Panel – transparency support
• Translations – new language additions, localization and long-string fixes
• MediaPlayer – new apis for Suspend/Resume
