New
Features:
* Added an option to use Base64 encoding for communicating XML data stream with the HTTP tunneller. Using this option can be required to work around this XML-related bug in PHP.
* Improved editor performance with large scripts if Wordwrap was enabled.

Bug fixes:
* On Windows Vista Business edition, SQLyog could crash while closing down. No other Windows OS (and also not any other Vista edition) was affected.
* Also a ‘hang™ could occur when closing down. It could happen with all systems, but Windows Vista was mostly affected.
* Schema Sync failed with identically named Foreign Key CONSTRAINTs on identically named colums of basically same type (that could still differ in LENGTH, SIGNED/UNSIGNED specification etc.)

Miscellaneous:
* When a PK is built on a string column using a case insensitive collation, SJA could try to insert a row where the PK was identical to an existing one as compared “COLLATION-wise” (ie. when only LETTERCASE differed). That would result in ‘duplicate key™ error and the sync job would abort. We have now reverted back to case insensitive camparison with string-based PK™s as before 7.0, but (to avoid data loss/overwriting) we will abort sync of tables when a string-based PK uses a binary or case sensitive collation.
