Release notes

New in v6.3.3:
- support for connecting via short connection links.
To create short connection links:
- enable Dev Tools,
- enable short links in Privacy & Security settings.
Only this and later versions of the app will be able to connect via these short links. Full links compatible with the previous versions are created at the same time, and you can choose which of the links to share.
Please note: if you use self-hosted servers, you need to migrate them to server v6.4.0-beta.1 or later.
