* Data distribution was running at too high of a priority, which sometimes caused other roles on the same process to stall. [6.2.5] `(PR #2170) <https://github.com/apple/foundationdb/pull/2170>`_.
* Loading a 6.1 or newer ``fdb_c`` library as a secondary client using the multi-version client could lead to an infinite recursion when run with API versions older than 610. [6.2.5] `(PR #2169) <https://github.com/apple/foundationdb/pull/2169>`_
* Using C API functions that were removed in 6.1 when using API version 610 or above now results in a compilation error. [6.2.5] `(PR #2169) <https://github.com/apple/foundationdb/pull/2169>`_
* Coordinator changes could fail to complete if the database wasn't allowing any transactions to start. [6.2.6] `(PR #2191) <https://github.com/apple/foundationdb/pull/2191>`_
