Changes (as compared to 8.53) include:
* With many servers/connections registered in SQLyog the drop-down list in the connections dialog would flicker. The flickering was introduced in 8.5.
* Query Formatter was not handling queries of size greater than 2 KB. Now the size is increased to 8 KB. The 2 KB limitation was introduced in 8.18.
* Import of data from .xlsx files from Excel 2007+ was failing with double-precision datatypes.
* Update-check failed if SQLyog was running behind a HTTP-proxy. The settings will now be detected. However proxies requiring authentication are not handled with this release.
