Version 1.0.72 - 2022-03-25 Qt6 Compatibility for Calibre Version 5.99.8+. Technical changes.
Tested on Calibre 5.99.8 with Zotero 6.03. Old versions of Zotero may or may not work.
The Qt6 version of Calibre available in Beta, 5.99.8, available for download here:

If you use ZMI, you should upgrade to Calibre 5.99+ and version 1.0.72+ of ZMI.
The use of .ris file exports via ZMI for linking "absolute paths" in Calibre within Zotero becomes highly problematic if your computing ecosystem changes in the future.
The use of Calibre "Portable" with ZMI is not recommended, since it creates its default Calibre Library underneath the path of the Calibre Portable application itself. See above.
