Each month, a new version of Alexandria is released with features, improvements, and/or bug fixes. COMPanion automatically updates all Cloud-Hosted users, but all Self-Hosted users will need to manually update the software. See the the Installation section below for instructions on updating Alexandria.
If you're Self-Hosted and having issues updating, make sure you're allowing full permissions to the Alexandria Support folder and temp/cache folders, particularly Cleanup at Startup.
