I have released a version 1.0.0 of pyPreservica which supports Preservica v6.3.
This version should also be compatible with python 3.7/3.8/3.9
It does not contain too much new functionality but it does have support for the new capabilities around replacing content objects. (i.e digitization re-scans), exporting DIPS in OPEX format and reading information from the PAR registry.
I have done work on the documentation to improve it and add more low level API information on each call.
If there is anything you would like to see added to pyPreservica please let me know.
