 # gdbgui release history
 
+## 0.15.0.0
+
+No new features, just bugfixes and compatibility fixes
+
+- Support only Python 3.9 (though other Python versions may work)
+- Use only the threading async model for flask-socketio. No longer support gevent or eventlet.
+- [bugfix] Catch exception if gdb used in tty window crashes instead of gdbgui crashing along with it
+- Disable pagination in gdb ttyy by default. It can be turned back on with `set pagination off`.
+- Upgrade various dependencies for both the backend and frontend (Python and JavaScript)
+
 ## 0.14.0.2
 
 - Pinned python-socketio version
