@girish
I thought Release Bell works only with GitHub.
Would be great if GitLab and others could be implemented.

@nebulon
2 months between Cloudron Tiny updates is too long!
Suggest 3 weeks max.

@nebulon The above graph depicts Hardware updates for 16.04 as now ended. Does this affect Cloudron installations on home servers (vis-a-vis VPS)?

What's happening with 18.04 --- 5 months down the line from first mention?

Trust that this isn't a bad omen, regarding two-man setups on which we are dependent!
