desktop client about available updates for core and apps. The notifications are \ 
made available via the notifications API.
    Multi bucket support for primary objectstore integration

Authentication

    Pluggable authentication: plugin system that supports different \ 
authentication schemes
    Token-based authentication
    Ability to invalidate sessions
    List connected browsers/devices in the personal settings page. Allows the \ 
user to disconnect browsers/devices.
    Device-specific passwords/tokens, can be generated in the personal page and \ 
revoked

yet, this will be added later. It is already possible to generate a device \ 
specific password and enter that in the current client versions.

on external storages (new mount option in external storage admin page)
    Direct links to the configuration pages for setting up a GDrive or Dropbox \

limit errors

avoid potential timeouts

    Added occ files:scan --unscanned to only scan folders that haven't yet been \ 
explored on external storages
    Chunk cache TTL can now be configured
    Added warning for wrongly configured database transactions, helps prevent \ 
"database is locked" issues
    Use a capped memory cache to reduce memory usage especially in background \ 
jobs and the file scanner

    Allow addressbook export using VCFExportPlugin

like timeouts (not used by clients yet)
