Altirra is a full cycle-exact emulation of all documented hardware features for the Atari 400/800, 1200XL, 600/800XL, 130XE, XEGS, and 5200 systems and is particularly notable for having a very well equipped debugger tool.

The device tree now better preserves selection when adding or removing devices.
AltirraOS updated to 3.32 with fixes for a couple of compatibility issues with the math pack, so B-Graph and House of Usher now work.
Fixes to the docking UI to reduce glitching when switching layouts or toggling full screen mode, due to panes becoming visible too soon and drawing in weird places before being moved to their final location.
Fixed a few timing bugs in the standard disk emulator. 810s now produce the head bump sound, the timeout was too short for Record Not Found (RNF) errors, and with long retries the idle timeout was sometimes kicking in too soon. Happy 810 and 1050 now have retuned receive rates.
The standard disk emulator now attempts to emulate track buffering for the Happy 810, 1050, and Speedy 1050 profiles, where the drive will burst transmit sectors from memory after reading in new tracks. This makes timing closer to the default modes for those drives. The Happy 1050 commands for toggling track buffering are now also support.
