This release fixes a rare crash as well as a regression bug introduced in 12.3.0.
Changes as compared to SQLyog MySQL GUI 12.3.0 include:
* 12.3.0 introduced a slowness when displaying the saved connections list with a large no. (100+) of saved connections. This is fixed now.
* Fixed a rare crash occurring sometimes when typing in the editor inside an invalid query longer than 128 characters. Auto-complete was at fault.
