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
