WinUAE has released version 6.0.0 of the Windows version of the UAE Amiga emulator, packing a truly terrifying number of changes, improvements, and fixes.
Major update to custom chipset emulation. Internally almost everything in main chipset emulation has been rewritten. Fastest possible/JIT mode chipset timing/sync had major changes which can cause side-effects. Bugs are very possible, especially in very rarely used features.

Going through the changelog is dizzying, ranging from an almost complete rewrite of the main chipset emulation for internal cycle accuracy, to running the emulation of the Denise/Lisa chips in a separate thread for better performance, to a ton of fixes and smaller updates.
Cloanto published a new version of Amiga Forever almost simultaneously.
Amiga Forever 11 with WinUAE as one of the emulators.
