- In Data.php (Helper) and corresponding Varnish configuration vcl file, added possibility to PURGE and PURGEREGEX to differentiate between regular expressions and just URL purges.
- In Cache.php Model in method collectTags() excluded top.menu block, since otherwise it will add all the top menu category tags to all the pages, so whenever a product is edited, all pages are purged in Varnish which would be pointless.
- Bugfix in Data.php (Helper) in method getCustomerBlocks() returning  instead of array_filter()
- In Data.php (Helper) repaired broken purgeAll() method to disable foreign key checks when truncating tables
