Important note: With the 12.0 release we changed registration keys. The new key is available for registered users from our Customer Portal. Users upgrading from a pre-12.0 version should have the new key available before installing. Until SQLyog 12.x is registered with the proper key, it will only display the registration dialog.
* Added option to prefix files with timestamp as well as ‘file per table’ option in “export as SQL dump” dialog. This is now available in Professional and higher versions of SQLyog.
* Launching “Visual Data Compare” from data synchronization wizard could fail. From ‘powertools’ menu there was no such issue. This bug was introduced in SQLyog 12.04.
* Escaped strings in a TRIGGER definition could have the escapes removed when copying and when using Schema Sync. This fix is actually a workaround for a bug in MySQL.
* When using HTTP-tunnel, SQLyog will identify itself to the webserver using a ‘user agent string’. This string now identifies SQLyog as an IE11-compatible application running on Windows 8.1. Before it was IE6 running on Windows XP. This has been reported to cause ‘denial of service’ with some hosting systems.
