SiyahKernel S3-v1.5.3
Update 1.5.2 -> 1.5.3: adb from jellybean sources. removed smooth scaling from STweaks settings (it was already disabled in v1.5 but I forgot to remove the settings from customconfig.xml). touch gesture size increased to 30 (by Tungstwenty). added NFS module. some tiny TMU modifications. Added lulzactiveq governor (by robertobsc). Changed memory mapped regions’ allocation sizes (by AndreiLux). fixed orbot problem. disabled kies daemon (thanks to AndreiLux).

SiyahKernel S3-v1.5.2
Update 1.5.1 -> 1.5.2:] set ro.debuggable to 1 in default.prop to get superuser working on cm10 (supersu users doesn’t need this update).

SiyahKernel S3-v1.5.1
Update 1.5 -> 1.5.1: fixed lpm mode (charging when device is off). fixed amplification settings being reset on some conditions. some mali related changes. removed lots of unused and unnecessary code. some pegasusq changes. removed arm topology related patches.

SiyahKernel S3-v1.5
rc1 -> release: Linux 3.0.15. CGROUP_TIMER_SLACK. added a little delay before applying STweaks settings on boot to fix gpu settings not being applied. speaker amplification is added back to stweaks but not as 0-63 but as 0-6, 0 will be the the same as stock. Touch gestures by Tungstwenty (example gestures for S3). Configurable notification led behavior in STweaks (blinking or fading). gpu boost on pressing keys (hard & soft).

SiyahKernel S3-v1.5rc1
beta6 -> rc1: insecure adbd. disabled eq for speakers. re-enabled speaker tuning . removed speaker amplification and tuning level (too many people complaining about distortion after setting it to max which is not a kernel problem. so, you will have to set it manually). lots of refactorings in sound part. set swappiness to 90 (only effective if you enable zram or swap).
rc1 -> release: Linux 3.0.40

update v1.5beta5 -> beta6
beta5 -> beta6: fixed speaker amplification and notification sound clamping (was only broken in beta5). added 5th GPU step. removed resume freq completely and added gpu freq boost on touch (0-disabled, 1-jump to step2 on touch 2-jump to step3 on touch). fixed MTP problem in OSX. Testing: Eq presets for speaker (re-enabled equalizer for speakers). led brightness limit removed (cherry-picked from cm10 kernel). reverted high brightness settings (if you want higher brightness increase max gamma to a higher level)

update v1.5beta4 -> beta5
beta4 -> beta5: fixed eq reset problem with samsung stock player. some gpu related tweaks. removed speaker tuning from STweaks but it is still available for those who want to enable it (look in /sys/class/misc/scoobydoo_sound)

update v1.5beta3 -> beta4
enabled swap.
enabled zram. patched mm and android files to include android specific zram optimizations (from note kernel).
updated pegasusq to the latest version which has min_cpu lock.

fixed mali currentlevel after resume.
enabled speaker_tuning
some autobrightness related changes (please comment on if this one or the original is better)

SiyahKernel S3-v1.5beta3
update beta2 -> beta3: adbd in lpm mode (charging while the device is off). when the device is charging in off state, limited the number of cores to 1, frequency to 200-800. Speaker amplification setting in STweaks.

SiyahKernel S3-v1.5beta2
update beta1 -> beta2: fixed fm speaker problem with dac_direct. disable hardware equalizer when the headphones are not attached to prevent distortion on the main speakers..possible fix for mtp problems on osx.

SiyahKernel S3-v1.5beta1
added (again) Entropy512's multicast filter patch to wifi driver
possible sound crackling fix. (please test and report)

SiyahKernel S3-v1.0.1
This kernel is for Samsung Galaxy S3 only. It will not work on Galaxy S2 devices.
CPU overclocking & undervolting (100MHz-1800MHz 18-steps, UV_mV and vdd_levels interfaces)
v(r) and sio I/O schedulers
triangleaway support
GPU undervolting & overclocking (600mV-1200mV, 40MHz-800MHz)
added hotplug governor (although I think it is much worse than pegasusq, I wanted to give you at least one more alternative). it is patched to support 4 cores and it will enable/disable cores based on the load only (old conventional way, but outdated)
mDNIe negative effect with home button (today I saw that it is also possible on iPhones and I got surprised. I didn’t know when I was implementing that)
optional smooth scaling for battery life freaks and for those who wants to use/test it on S3.
autorooting
extweaks support for most of the available features
increased charging speed (optional. use extweaks to set charging current levels)
2ndcore support. although we have 4 cores you’ll be able to force single, dual, triple and quad core modes with or without hotplugging.
CIFS
proprietary exfat support for external sdcard
Autogroup

update (15/06): compiled with linaro toolchain 4.7 2012.05 and fixed extweaks profile problem.
