There are now new builds of the Z-code interpreter Windows Frotz, and the Glulx interpreters Windows Glulxe and Windows Git out. The main new feature of these is that, since Zarf added MP3 to the Blorb specification, these interpreters now support MP3 music files in Blorb files too.
The new build of Windows Frotz has a few other fixes too, notably that when playing Z-code version 1 and 2 games, input encoding matches the Z-Machine specification section §3.7.1, so that the unusual way that the dictionary word “pdp10” is encoded in Zork 1 works.
