A new release of mGBA, version 0.8.3, is available. This version is a bugfix release, which contains many stability and accuracy fixes. Notably, an issue leading to stuttered rendering and eventually a crash, mostly on AMD GPUs, has been fixed. However, there is an outstanding bug in all 0.8 versions that causes flickering in Advance Wars games. This can be worked around by using a dump of the official BIOS, or using 0.7.3 until it is fixed. An extensive list of changes follows after the cut.
