Beta V0.15 has been released. It’s mostly recent bugfixes, and a new feature to enable variable room descriptions. Read the full Release Notes.
As @Goodstarbuck discovered, the version number wasn’t updated when I first posted this. I fixed that, so any early updaters may want to just run upgrade in-game again to grab the latest version file. There were no other changes, so no need to do ‘load all’ or ‘migrate’ or anything.
