InnoDB: Warnings printed to the error log for long semaphore waits did not provide information about the latch owner.InnoDB: A Performance Schema instrumentation was added for tracking redo log buffer memory allocations.InnoDB: The ut::make_unique library function in the InnoDB sources now permits specifying the type of field allocated.InnoDB: The sync_array_detect_deadlock algorithm used by the semaphore deadlock checker in debug builds was simplified in terms of code and time complexity, and an implementation of the algorithm was introduced for use in release builds. InnoDB: The minimum I/O buffer size calculated during an index creation operation did not align with the I/O block size, permitting a record to exceed the buffer boundary.
