Bugs Fixed

Querying INFORMATION_SCHEMA GLOBAL_TEMPORARY_TABLES table would crash threads working with internal temporary tables used by ALTER TABLE. Bug fixed #1113388.

FLUSH INDEX_STATISTICS / FLUSH CHANGED_PAGE_BITMAPS and FLUSH USER_STATISTICS / RESET CHANGE_PAGE_BITMAPS pairs of commands were inadvertently joined, i.e. issuing either command had the effect of both. The first pair, besides flushing both index statistics and changed page bitmaps, had the effect of FLUSH INDEX_STATISTICS requiring SUPER instead of RELOAD privilege. The second pair resulted in FLUSH USER_STATISTICS destroying changed page bitmaps. Bug fixed #1472251.

If a new connection thread was created while a SHOW PROCESSLIST command or a INFORMATION_SCHEMA.PROCESSLIST query was in progress, it could have a negative TIME_MS value returned in the PROCESSLIST output. Bug fixed #1379582.

Other bugs fixed: #768038 and #1472256.
