Dropbox email notification option: students can now choose to email instructors when they upload to a dropbox, and vice versa (see SAK-10925) (note that this is a first pass through dropbox email notification options - we hope this will develop in the future)
Dropbox hot folders: instructors can now see a visual indication of which folders have been recently updated (choice between updated in last 1 day, 2 days, 3 days, 1 week)
Minor UI improvements
Removal of inappropriate options from Dropbox interface (e.g. 'availability and access' settings that appear in Resources tool should not appear in Dropbox and have now been removed)
An improved, accessible dropdown widget for Add and Action menus (see SAK-10924) (note that although this is now accessible, no particular change is visible in the UI)
Resources is now somewhat faster (see below)
Technical improvements
Preliminary support (as part of a longer-term transition through 2.6) for the integration of JSR-170 repos, riding beneath CHS
Rewritten underlying Storage of entities to reduce memory usage and cpu load.
Some database refactoring to eliminate bottlenecks in the underlying chs.
