Ixtab, All,
please find attached source patch for 5.4.3.2 support and CollectionsManager_2.7.0.zip. I did test that import from calibre work for 5.4.2 and 5.4.3.2. Did NOT test ANYthing else. Would have pushed to ixtab repo but either I do not have permissions or could not figure out how to do it properly (have never used git before).
P.S. I could NOT find jars for 5.3.2 so this version (2.7.0) won't work for 5.3.2. If someone points me to bin, img or jars themselves for 5.3.2 I will recompile.
P.P.S. Ixtab, my respect for coding this!
----
I removed the binary package to avoid confusion
