Release 2.5.57 (24th November 2017):
Security issues:
TL-16270 360° Feedback now correctly disposes of the user's access token when no longer needed
Previously if a user accessed a 360° Feedback instance using a token, that
token would be stored in the user's session and would allow them to access
the 360° Feedback as a user (not with a token).
The token used to access the first 360° Feedback instance is now disposed
of correctly.
Bug fixes:
TL-16435 Fixed missing "Notification does not exist" string
