Notable Items
InnoDB
* InnoDB no longer acquires advisory file locks by default (MDEV-24393)
* Encryption: Automatically disable key rotation checks for
file_key_management plugin (MDEV-14180)
* Some fixes from MySQL 5.7.35 (MDEV-26205)
* Fixed scrubbing on AIX (MDEV-26110)
* buf_pool.flush_list corrupted by buffer pool resizing or
ROW_FORMAT=COMPRESSED (MDEV-26200)
Optimizer
* A query that uses ORDER BY .. LIMIT clause and "Range checked for each
record optimization" could produce incorrect results under some
circumstances (MDEV-25858)
* Queries that have more than 32 equality conditions comparing columns
of different tables ("tableX.colX=tableY.colY) could cause a stack
overrun in the query optimizer (MDEV-17783, MDEV-23937)
* "Condition pushdown into derived table" optimization cannot be applied
if the expression being pushed refers to a derived table column which
is computed from expression that has a stored function call, @session
variable reference, or other similar construct. The fix for MDEV-25969
makes it so that only the problematic part of the condition is not
pushed. The rest of the condition is now pushed. (MDEV-25969)
* A query with window function on the left side of the subquery could
cause a crash. (MDEV-25630)
* Fixed the issue fixed in MySQL Bug #76803: DML or locking SELECT
statements that use outer joins could produce this warning in the
error log: [ERROR] InnoDB: Unlock row could not find a 3 mode lock on
the record. (MDEV-26106)
Security
* Fixes for the following security vulnerabilities:
* CVE-2021-2372
* CVE-2021-2389
