- Let user set avatar in nextcloud if LDAP provides invalid image data
- Improved logging of smb connection errors
- Allow admin to disable fetching of avatars as well as a specific
attribute
- Allow to disable encryption
- Update message shown when unsharing a file
- Fixed English grammatical error on Settings page.
- Request a valid property for DAV opendir
- Allow updating the token on session regeneration
- Prevent lock values from going negative with memcache backend
- Correctly handle users with numeric user ids
- Correctly parse the subject parameters for link (un)shares of calendars
- Fix "parsing" of email-addresses in comments and chat messages
- Sanitize parameters in createSessionToken() while logging
- Also retry rename operation on InvalidArgumentException
- Improve url detection in comments
- Only bind to ldap if configuration for the first server is set
