The last months have been rather calm for Replicant development, no big changes or improvements were made. That doesn't mean the project stalled: instead, we added support for some new devices. The previous set of images added support for the Galaxy Tab 2 10.1/7.0 in their 3G versions and we were requested to provide images for the WiFi-only flavors of these tablets as well. Since it only requires very little work, we were able to quickly fulfill that request, even though we couldn't test it ourselves (you're more than welcome to spot and report issues about these devices).
However, the biggest part of what motivated us to build and release new images is the support for the Galaxy S3 device in its international GT-I9300 GSM version (not the LTE one or any other country-specific variant). Currently, only graphics acceleration, camera and GPS support are missing (some other features may need non-free firmwares that run on separate chips). A couple of other things are also missing due to technical limitations (NFC, FM radio).
We are still trying hard to bring Replicant to the Goldelico GTA04, but it couldn't make it to that release either as we still need help bringing a reliable Android kernel to that platform (DM37x).
A more complete changelog is also available, highlighting in details what was changed. Special thanks to the team at CyanogenMod who fixed EXIF in the free Galaxy S2 camera module implementation I wrote but was too lazy to correctly implement EXIF into.
You can download the images from the ReplicantImages page and find installation instructions as well as build guides on the Replicant wiki.
