Release Notes Version 4.2.x Beta
Please Note that LiquidFiles v4.2 is currently in Beta. The following applies to beta releases:
- To update to Beta releases, you need to enable checking for Beta releases in Admin → System → Update, and then select the beta release at the same page.
- Beta Releases are only available to Licensed LiquidFiles systems (not trial/demo).
- Beta Release numbers begin at .51, so v4.1.51 is the 1st beta release of v4.2, v4.1.52 will be the 2nd beta release of v4.2, and so on.
- Expect a faster release cycle for beta releases as we're working up towards the full release.
- We're aiming for the same high quality as with non-beta releases, and any new functions and changes can introduce unforseen problems. We will release fixes quickly when anything is discovered.
Major changes from version 4.1 to version 4.2
- Removed legacy Plupload function that had been used in earlier versions of LiquidFiles. The last remaining function was uploads in Shares. We've finally migrated away from Plupload in LiquidFiles v4.2. Along with a few other improvements along the way, we've seen increased upload speeds of up to 30%.
- Added multi-select in shares to select multiple files or folders to move or delete at once.
- Added function to sort files and folders in shares.
- Trashed files are now automatically deleted, on default after 14 days.
- Added custom admin levels, it's now possible to create non-admin groups with some admin privileges for Shares, Filedrops, Users, Pools and Branding.
- Previous User Admin and Pool admins functions now use custom admin levels. If you haven't used User Admin or Pool Admin groups, they will be removed.
- Sessions Timeout now defaults to 6h.
- Outlook Web sessions now use the Session Timeout.
- Persistent cookies now expire after n days of inactivity instead of an absolute time.
- The Return-Path is now set to the users email for local users and the Email Sender Address Policy is set to Local Domain Emails use their own addresses or Email Sender Address for system email only.
- Added a function to record delivery of emails for Secure Messages.
- Security: Added support for enable Ubuntu Pro in FIPS mode.
- Security: Login Limit. If a user fails to login 10 times in a row, the user will be required to change their password (inspired by a vulnerability assessment by Frédéric Goossens, Pentester, Davinsi Labs).
- Security: If someone is trying to authenticate with a non-existent account and Friendly Error messages is disabled, that non-existent email will be blocked for logins for about one day (randomized between 18 and 36h).
- Security: Stronger input validation for admin functions (the stronger input validation had already been added to user visible functions in previous versions of LiquidFiles).
- Security: Friendly Error messages now defaults to disabled.
- Security: Stronger URL filtering in nginx.
- Cleaned up YAML handling, shouldn't be any visible changes and it can potentially affect uploading/handling locale files.
- Updated the internal queue worker engine.
- Updated internal functions like Ruby and Ruby on Rails to later versions.
