- ADDED search field below data tables is now using the regular expression syntax. For example, a search for "google|yahoo" would match all rows containing "google" or "yahoo". All search strings containing any of the special characters from this list: . \ + * ? [ ^ ] $ ( ) { } = ! < > | must be escaped with a back slash, eg. if you want to search for keywords containing "piwik!" you would search for "piwik\!". 
- ADDED new configuration option: default number of rows returned in API responses "API_datatable_default_limit = 50"
- REMOVED the automatic generic filters. The limit and sort and safe decode are applied by each module when necessary.
- removed exact match filter. Now all searches are using regular expressions syntax. Exact match can be done using ^exact search here$
- fixed notice when natural sort on a non existing column
- fixed CSV export for datatable_array
- clarified code for plotting multiple lines in an evolution chart
- FIXED #624 Added icon "save as image" below all graphs (next to the Export icon)
- moved all JS functions into the piwikHelper static class
- added example in ExampleUI plugin to plot only visits from google and yahoo! in 4 lines of code
- added message when flash is disabled and graph not showing, linking to piwik faq. 
- added expressInstall.swf feature
