Hi everyone!
While we are working on ADOM 3.2.0 we decided to do one more release in the 3.1.x line fixing another important crash bug related to to altars not being found when switching a level. Another (minor) bug fix relates to skill improvements on very high character levels (so it probably would not have affected 99% of all players and was only a visual problem anyways). Nonetheless ADOM 3.1.5 fixes these two problems and will be installed automatically on your system.
Here you find the details: http://www.adom.de/home/changelog.html
Enjoy playing!
