Here's whatsnew:

-Fixed M6532 RIOT timer emulation. More testing is needed, but the changes so far have fixed several ROMs that didn't work before.
-Fixed issue with weird characters in the debugger disassembly when loading .lst files.
-Fixed bug where entering the debugger for 4A50 and E0 carts caused the ROM to be frozen afterwords.
-Removed logic whereby starting a ROM from something other than the built-in launcher wouldn't allow the user to go back to the ROM launcher.
-Fixed bug (hopefully) with the app icon not showing on the Stella window. Further testing is needed, since I can't duplicate the error myself.
-Fixed default snapshot folder issues; the folder will now be automatically created in the same place as state folders, ini files, etc (whereever that may be for your platform).
-Re-added 'lastrom' functionality, where Stella will remember and auto-select the last ROM that was successfully launched in the ROM launcher.
-For Stella developers, fixed SpeakJet emulation so it compiles again. No improvements have been made to the emulation itself, though.
