The following is a short list of changes introduced with version 4.1.0.6 (20/12/10) and version 4.1.0.7 (21/12/10).

Version 4.1.0.6 (20/12/10).
This was mainly a behind the scenes update, nevertheless, quite a big one at that.
- Document Details Window: changed the ‘next’ and ‘previous’ hotkeys from ‘ctrl + arrows’, to ‘ctrl + shift + arrows’. This now matches the shape of other hotkeys in EPPI-Reviewer.
- Behind the scenes: we have published some exciting and experimental code that is available to internal users only. The aim is to provide an additional way to speed up the screening phase for those situations where the number of items found in the search phase is huge. Both the code and the methodology will need to undergo serious evaluation and testing before being released to the public.

Version 4.1.0.7 (21/12/10).
This was exclusively a bug-fix release, to fix a couple of minor issues introduced with version 4.1.0.6 and that slipped through our testing phase:
- Changing review from within EPPI-Reviewer caused an error. This could cause discomfort (requiring to ‘refresh’ the browser and re-authenticate to change review) to some users and is now solved.
- Find Similar Documents window: the TF*IDF method to extract terms had stopped working; all other term extraction engines were unaffected. This is now fixed.
