Recent Releases Apr 2024 03:15 minor feature: Added microthat adds a missing default value to the backup reports. Apr 2024 10:16 documentation: This build is intended to be the last build that uses.Net4 (aka.Net Desktop). Future builds are expected to use.Net8 and will require a manual update, because the.Net builds are no longer operating system independent. The upside is that there are fewer dependencies (no more Mono). and execution times are greatly improved. Removed donation messages. Updated MacOS Installer license text. Updated installer to support future manual upgrade. Added information to reports when encountering an exception.
