After only 11 days, the new Second Milestone is available. We fixed many issues reported in M1 and we supported some new features we are sure you’ll appreciate: 40 issues in total. Please help us to test OrientDB 2.0-M2 so that we can release a stable final 2.0 in 10 days.

Can I use OrientDB v2.0-M2 in production?

No. This is not the final 2.0 version. This release is the second milestone (M2 stands for Second Milestone) of 2.0 on the path to the final version in the next 10 days. We suggest using OrientDB v2.0-M2 in development and test only. If you plan to go in production before October 10th, we suggest staying with OrientDB 1.7.x. Otherwise, go ahead and use OrientDB 2.0-M2.


Is 2.0-M2 compatible with previous versions of OrientDB?

You can open any database created with past versions of OrientDB. In order to use the new binary serialization, you are required to export and re-import the database. For more information, take a look at Migrate from 1.7.x.
