On the new features front, rfe #1634 was discussed during the last IRC meeting and received the green light to be implemented. This rfe requested not to group items in the navigation panel when there is only a single group and no other items or groups in a particular sub tree.
Bug #4934 reported the shift + click to apply selected function to all rows in insert/edit page was not functioning in some browsers. Since shift + click event was non standard on browsers we decided to remove the feature altogether. This was also carried out during the week.
Feature requests implemented
#1634 Don't group tables in tree if the result has only one group
#1677 Support spatial indexes in table create form
Remove support for Shift + Click on function name to apply to all rows in insert/edit page
During the latter part of the week, I engaged in analyzing the performance issues and fixing them. This was based on the profiling carried out earlier using xdebug. I attended to table browse, insert and edit pages since they showed highest performance deterioration competed to 3.x series.
