Hi Pascal,
databases created with 7.8 cannot be opened by older versions of BaseX (the last change came with the upgrade from 7.7.3 to 7.8). I can't guarantee you that 7.7.2/7.7.3/7.8 are fully backward-compatible, but down to version 7.6 this should be the case.
Regarding the GUI freezes[1]: I never use the .jar file, yet I experience the freeze from time to time (I always start with -Xmx512). Using -Xmx32m on purpose still doesn't reproduce the issue. In fact, I wasn't able to reproduce it at all during the last days ... we'll keep an eye on that.
Cheers, Lukas

BTW, 7.7.2/7.7.3/7.8 DB format seem to be backward compatible with earlier releases (like 7.6). Can you confirm? Also, is 7.8 format different than 7.7.x? thanks *P

Hi Pascal,
Recently upgraded to 7.7.2 from 7.6 and getting UI freeze on MacOSX when
I try to open existing databases.
I also experienced this issue once or twice but wasn't exactly able to reproduce it on purpose. Your report simply tells me that there's indeed an issue with 7.7.2/ 7.7.3 and we should take a closer look at it - thanks for the report. Do you also experience the same freezes with the latest stable snapshot (7.8)?
When opening from the interactie command prompt, I get a message that the format has changed and I need to rebuild indexes.
I would serialize the database content to disk with 7.6 and create new databases from the exported files. Between version 7.7.2/7.7.3/7.8 the database format changes again - another reason to consider giving version 7.8 a go.
Sorry for not being of too much help here ...
Cheers, Lukas
