Changes (as compared to 8.15 RC) include:
* Execution of some queries would be slow with Query profiler/EXPLAIN extended selected. Most important queries with a UNION were affected. Technically it was an issue with the Query Formatter code and how it ‘hooked’ into the program. This bug was introduced in 8.0.
* Copy database/table could be slow if BULK INSERTS option was selected in ‘preferences’. This bug was introduced in 8.15 beta 1.
* 8.15 RC could crash when executing a LOAD DATA statement. This first RC was build with a recent 5.1 client library. Before 8.15 RC we used a 5.0 library. We have now reverted back to 5.0 (5.0.86 client library is used with this release). Issue with the 5.1 client library is not fully understood but it may be related to known memory issues reported with it.
* Functionality change: Before this release we stripped out the database name from Stored Program and View SQL-code when generating SQL-dumps and and when copying a database to another host. Also Schema Sync did with VIEWs. This was in order to make it easy to import/copy to another database. However with tables named identical to the database and when database names was a substring of a table name it failed sometimes. We realize now that SQL code inside Stored Programs and Views may be so complex that parsing for the database name and stripping it is not safe. With this release we have stopped this ’stripping’ and Stored Programs and Views will be dumped by SQLyog identically to what ‘mysqldump’ does.
