As most of the GSoC projects in phpMyAdmin go on quite well, we're already merging some of the new features to our master branch. You can try them all on our demo server and you are welcome to report any issues found :-).
First big part which has been changed is rewriting of server status page done by Tyron Madlener. It now provides more information, provides real time charts and much more. This change also included change in charts produced in other places in the code, so they are now more interactive and allow easy exporting.
The browse mode got improved as well, you can now reorder columns (by Aris Feryanto) and there are new options for displaying GIS data (by Madhura Jayaratne). While speaking about GIS, I have to mention another new feature - rendering of GIS data, either as polygons or on OpenStreetMap map (you can see it by clicking on "Visualize GIS data" link on browse page, it is not possible to link it directly due to XSS protection).
Many smaller changes are being done by Thilanka Kaushalya to convert various parts of user interface to AJAX.
And last but not least we have nice support for editing stored procedures and functions. Support for events and triggers will follow soon. All these are being done by Rouslan Placella.
I hope you will like these new features and thanks to all our GSoC students who are doing great job.
