Angband 4.2.5
Angband 4.2.5 is now available for Windows, macOS and as source. It can be downloaded from the official site.

There are two main thing to mention in this release:

The return of the borg, thanks to excellent work by agoodman
A huge amount of bugfixing, code improvement, project admin and general good work from backwardsEric

It's about 18 months since the release of 4.2.4, so a release was overdue and the borg inclusion gave me the necessary push to actually get it out. Thanks chiefly to backwardsEric (but also other people, even including me) the game is in a very good state. I don't think there's really been much discussion of what would be in a potential version 4.3 since the 4.2.4 release announcement, so I guess the comments there still apply.

Summary of changes:

return of the borg
fix problems caused by some necromancer spells
hydras now bash rather than open doors
clarification of symbols on the character sheet
torch random artifacts can drop deeper in the dungeon
improvements to stats and debug commands
autobuild for NDS, DOS, msys2 and nmake
too many areas of code improvement to mention individually

As always, thanks to everyone who has contributed in any way to Angband development.
