Please consider the full list of user-visible changes below.

Compatibility

Tarantool 2.x and 3.x are compatible in the binary data layout, client-server protocol, and replication protocol. It means upgrade may be performed with zero downtime for read requests and the order-of-network-lag downtime for write requests.

Please follow the upgrade procedure to plan your update actions.

Users of Tarantool 2.x may be interested in the compat options that allow to imitate some 2.x behavior. This allows to perform application code update step-by-step, not all-at-once.

Bugs fixed

Vinyl

• Fixed a bug when the dump task scheduler was not unthrottled by box.snapshot() (gh-12342).
• Fixed a bug when Tarantool crashed instead of raising an error in case it failed to apply an upsert statement.
