The latest stable release of CyanogenMod 11 M9 is available to download now, and in addition to bringing a whole bunch of new features and improvements, it adds support for two new smartphones — the HTC One M8 and the Sony Xperia Z2. This is the first stable (non-nightly) CyanogenMod release for both of these devices.

CM11 M9 is based on Google’s latest Android 4.4.4 KitKat code, but it includes a plethora of apps, features, and tweaks that you don’t get with a pure Android ROM — such as the much-loved theme engine, which lets users quickly and easily skin almost every element of the user interface.

The latest stable release makes improvements to the theme engine, allowing addition user interface elements to be altered. It also makes changes to the lock screen, flashlight, quick settings, Bluetooth, and lots more. Here’s the full change log:

* Themes support for additional UI elements
* Heads Up Notifications – Bug Fixes
* Lockscreen – Allow doubletap to sleep when using secure keyguard
* Torch – Improve performance
* Safe Headset Volume – prompt when interfering with 3rd party device (Jawbone, Square, etc)
* Center clock support
* Quick Settings – respect locale changes on additional tiles
* Proximity Wake-Up support – prevent accidental wake-up of device by checking to see if proximity sensor is blocked (eg. Device is in a bag or pocket).
* Spam notification filtering – Set notifications to auto-ignore based on content (perfect for those pesky games that want you to ‘Save 20% on our new game’). Long-press offending notification to set as ignored; manage in Privacy settings.
* Settings Search – Additional improvements and highlighting
* Data Usage Info – Add support for CDMA devices without sim cards
* Bluetooth – Add additional A2DP profiles
* Bluetooth – Disable AVRCP 1.5 by default (fixes various car unit compatibility)
* Email – Fix saving attachments to storage for POP3 accounts
* Translations (Thanks CM Crowdin Team!)
* Account for Play Services induced wake-locks
* Fix encryption on some LG Devices
* Dialer – add support for Korean and Chinese to smart-dialer

You can download CM11 M9 now from the CyanogenMod download center, but if you’re flashing it for the first time, ensure you have first backed up your device, unlocked its bootloader, installed a custom recovery, and fully prepared your handset to receive third-party firmware.
