2023-05-10 | 1.2 | 47.2.A.10.107

Updated to T QPR2 release (LineageOS upstream)

Updated to May 2023 Security updates (both ROM and kernel)

Our kernel now includes updates by CIP and is up-to-date with tag st40 - thanks also to Flamefire for help with some of these (1)

Reduced zram size to 25% (1gb) of out total RAM to have more to use freely

Updated BT stuff for QPR2 (maybe offloading is working again? needs confirmation)

Added the option to reflash the mbn via OpenCS (see Xperia Parts) - thanks also to shank03 & Flamefire (2)

Fully enabled IMS on Congstar Germany via overlay on lilac

Possibly some battery/performance optimizations here and there

Fixed Android Auto support

Added new LineageOS "Charging control hal" for battery charging care (3)

Maybe more I forgot...

(1) The CIP kernel includes fixes for issues and security vulnerabilities from 4.14 kernel (see https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git)

(2) A somehwat lengthy explanation: This option is off by default on fresh installs. When upgrading, this should be enabled because we enforced this for everybody previously. However, this option is only required for certain carrier mbns that enable IMS. Personally, I know that the O2/Telefonica Germany mbn needs this, otherwise you get a crashing modem at every boot (unless you switch to 3g before rebooting and back to LTE after boot). I generally recommend playing with this option, and if you don't need it (e.g. modem doesn't crash on boot), just keep it off - like mentioned before, this is now the default behavior of OpenCS on fresh installs anyway.

(3) This is not finalized or merged upstream in LineageOS yet, but seems like a nice feature to have and test drive already. Some bugs may be possible.

2023-01-08 | 1.1 | 47.2.A.10.107

Updated to T QPR1 release (LineageOS upstream)

New default camera app (LineageOS upstream) - yes, we cannot change video fps currently (thanks Sony!)

Any other updates by LineageOS upstream

Kernel security updates (also thanks to Flamefire)

Dropped keyprovd service - it is useless on unlocked BL anyway

Show 4G instead of LTE icon - saves some space too

Enable IMS by default - this still only works if carrier is supported

Fix some selinux denials (also thanks to Flamefire)

Fixup ViLTE dependencies - this might in theory work again, but it's not enabled yet

2022-10-03 | 1.0 | 47.2.A.10.107

Initial release
