Change: Raw data export is no longer producing zeros for non-selected checkboxes (checked=1, unchecked=0) on the survey form if the question was not seen by the respondent.
Fixed bug: For admins: Some logging statements relating to clustering were written to standard out. These statements did not react to the log level set for the module, resulting in a lot of debug-level statements.

Fixed bug: Survey locks not released on user deletion.
Fixed bug: Branching filters were not updated correctly when the respondent was using back button and changing responses for questions with branching conditions. Only happened when questions affected by filter also had conditions attached.

Improved: Imported invitee data can now hold up to 65535 characters per entry.
Improved: Respondent attribute data can now hold up to 65535 characters per entry.
Fixed bug: Branching with redirect to a URL did not work with multiple branches/URLs.

Improved: Increased the default size of cache for folders to 20mb (was 5mb).
Improved: First login after restart could take a long time due to loading of survey/folder lists into cache. Now done in a background thread.
