Cloudron 3.1 released

[girish]

Cloudron 3.1 is now available for all. You can read more in our blog post.

Highlights:

• Add UDP support
• Docker addon
• Backup interval is now configurable
• API tokens can now have a name

Unfortunately, one important change about backup encryption did not make it to this release. We will get it done in the next release. We had to push this release out asap for business reasons.
