Hi Mark,

we have been running thru the setup and issue tracking for several
week now and find no noticeable defects. Great Job all! (we are
actually going to start using it in a “Beta” mode for our production
process - to validate our internal processes.)

I can not endorse using the beta branch in production. We are still
going trough destructive migrations that will leave your data in an
inconsistent state or that will create the necessity to manually update
your database when you continue to use the 3.0.0.*. While a final
migration that moves pre 3.0.0.-versions to 3.0.0. will be written,
that one will not migrate through all the 3.0.0.pre* versions. Proceed
with caution. This instance itself, at the time of writing, is a rails2
version.

Is there any “official” time frame when a “production ready” release
will be made?

No. The release of plugins can be seen in this timeline though:
https://www.openproject.org/timelines/projects/openproject/timelines/23

Is there a plan to release the “Stable” base, while still working on
additional plugins?

We have recently released the meetings plugin
(https://github.com/finnlabs/openproject-meeting), which works with
3.0.0.pre10. We will work to keep the released plugins stable to work
with the most recent core, and to keep the plugins stable to work with
each other. However that “stable” refers to the code working from
scratch, not necessarily from the point where you already had data in
your system.
