InnoDB: The buf_validate() function in the InnoDB sources was optimized, improving performance on debug builds.Similar functions (ut::make_unique_aligned and ut::make_shared_aligned) were added for types with extended alignment. InnoDB: Performance Schema aware ut::make_unique and ut::make_shared memory management library functions were added to the InnoDB sources.InnoDB: Numerous Trying to access missing tablespace errors were printed to the error log following a restore operation.InnoDB: The ut_time() infrastructure in the InnoDB sources was replaced with a type-checked standard library implementation.The OVERLAPPED structure was not provided. The operation was performed as an overlapped (asynchronous) operation, which requires a OVERLAPPED structure containing a handle to an event object. InnoDB: A hole punch operation on Windows caused a failure.InnoDB: A latch release and reacquisition mechanism was introduced to reduce the amount of time that threads spend in critical sections protected by a global lock system latch.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.
