[B][U]29/08/2017[/U][/B]

* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Shifted to using a kernel driver for disabling touch devices
when the screen is off instead of a user service for that. [/B]

* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Updated kernel to the latest upstream AOSP and
CAF tags. There should be a noticeable performance boost. [/B]

* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Shifted to using OSS GPS code instead of prebuilt libs.
Location applications should be getting and reporting
satellite fix information properly. [/B]

* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Disabled cpusets support, which was slowing
down the system performance. [/B]

* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] The auto time zone feature should now be working
proper, (that is, without resetting the time zone
to 0000 UTC).[/B]

* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] Data should be working fully on all devices. [/B]

[B][U]22/08/2017[/U][/B]

[B][U]01/06/2017[/U][/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Updated kernel and prima (wifi)
driver to the latest caf branch LA.BR.1.2.9_rb1.18[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] The reboots caused by errors in the
prima kernel driver should be gone.[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] F2FS should work completely now.
Updated F2FS code from upstream kernel sources and enabled
security extended attribute support (for SElinux) to fix
android support.[/B]

[B][U]15/05/2017[/U][/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Wifi driver is now built-into the kernel again.[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B][B] The sleep issue should be fixed in the latest build.
This was due to the failure to set a critical kernel
variable at boot because the kernel init system was
not interpreting a boot command line variable correctly.[/B]

ROM.[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] F2FS is enabled in-kernel, so F2FS filesystem
mounting and formatting should be working fully.[/B]

[B][U]05/05/2017[/U][/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Wifi driver is being built as a module for now,
transitioning to a new kernel somehow broke the ability to build
it into the kernel binary.[/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Transitioned to a new kernel based on T560NU and
J500H MM kernel sources (J500HXXU2BPJ9 and T560NUUES1BPL1). [/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] In-call audio should now work fully without having to
toggle the loudspeaker. [/B]

* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] Vibration should be working for SM-G530MU. The kernel
config now specifies the correct vibration driver. [/B]

[B][U]14/04/2017[/U][/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Wifi driver is now built into the kernel. Should
(slightly) improve speed of enabling/disabling wifi. [/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Updated kernel and wifi driver to LA.BR.1.2.9_rb1.14[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B][B] Updated RIL in-call audio fix, microphone should now
work proper after the regression from last build.[/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Builds now use sdcardfs from Google. This should
result in faster file operations on the sdcard overall
compared to using FUSE as an overlay.[/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] There have been several other changes as well,
mostly to the underlying structure of the kernel and device trees.[/B]

[B][U]01/04/2017[/U][/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] LineageOS updater can reboot to recovery properly.[/B]

[B][U]30/03/2017[/U][/B]
*[B][[COLOR="Blue"]FIX[/COLOR]][/B][B]Data and SMS should be functional on all devices.
You may need to set APN settings again and reboot for data to work.[/B]

[B][U]28/03/2017[/U][/B]
*[B][[COLOR="Blue"]NOTE[/COLOR]][/B][B]Added SM-G530MU.[/B]
*[B][[COLOR="Blue"]FIX[/COLOR]][/B][B]Data and in-call audio should be functional
on all devices.[/B]

[B][U]26/03/2017[/U][/B]
*[B][[COLOR="Blue"]NOTE[/COLOR]][/B][B]SM-G530FZ builds *should* be functional.[/B]

[B][U]09/03/2017[/U][/B]
*[B][[COLOR="Blue"]NOTE[/COLOR]][/B][B] Added SM-G530FZ.[/B]
* [B][[COLOR="Red"]FIXED[/COLOR]][/B] [B] Rear camera view in Snap camera was distorted. Now fixed. [/B]

[B][U]16/02/2017[/U][/B]
*[B][[COLOR="Blue"]NOTE[/COLOR]][/B][B] Unified the T/T1/W into one image. They are essentially the same device.
This should simplify development on my part and make it easier for everyone to
get the updates. And I can also be absolutely sure about bugs
since we'll be using the same image. [/B]
*[B][[COLOR="Blue"]NOTE[/COLOR]][/B][B] Decreased minimal scaling freq. to 200Mhz.
The previous scaling frequency minimum of 800Mhz was pretty high,
and could quickly cook your phone and kill power on mobile devices.
Lowering to 200Mhz should significantly extend batery life
on the stock scheduler. [/B]

There are a lot more minor tweaks and fixes. I don't have the time to constantly be updating this; I expect you'll read the

changelogs anyways since I take my time to write the commit messages in detail.

[B][U]12/01/2017[/U][/B]

[B][U]10/01/2017[/U][/B]
*[B][[COLOR="Blue"]NOTE[/COLOR]][/B][B] Refactored the project repositories. [/B]

[B][U]20/01/2017[/U][/B]
