[25.2.3] - 2025-07-07

Fixes

- Fixed a bug which broke intra-replicaset replication when upgrading from 25.1.* to 25.2.*.
  Note that clusters broken by this bug require some manual actions in addition
  to this fix, but newer version should upgrade fine. Note also that this fix
  does not include the actual schema upgrade procedure, so the cluster will
  still have a schema of the older version of picodata.

- Fixed incorrect validation check for max number of users.

- Preserve parameter types provided by client.
  Previously, we'd completely replace parameter types array with the one
  derived by the Sbroad's type system. As a result, sometimes the type
  could implicitly change from VARCHAR to TEXT, causing various problems
  to client drivers.

- Fixed a bug which could sometimes lead to unconstrained stream of requests
  from a failed instance (implemented expontential backoff for sentinel requests).

- Fixes unnecessary vshard router and storage config updates.

- Fixed a bug when parsing RFC 3339 timestamps with a date-time delimiter other than `T`
  resulted in an error.
