Finally release 2.1.0 is here!
It's been a while since work started on this release.
Anyhow, as mentioned in README file of this repository, the actual releases happen in papermerge/papermerge-core repository (current repo i.e. ciur/papermerge is meta repository which keeps track of all other repos).
The biggest change what happened since last beta release is that REST API interface is now fully OpenAPI compliant.
OpenAPI schema is now stored in a separate repository. And what is really important here is that OpenAPI schema is actually used to generate REST API clients which is used by various clients like papermerge-cli.
Enjoy!
