New features and improvements
Serv-U 15.2.3 is a security-focused release, including:
- SQLite upgraded to version 3.26
- Support for Content Security Policy
- Silent installation improvements
- Licensing framework changed (see Upgrade notes)
The Serv-U licensing framework has been changed in Serv-U 15.2.3 and a new license key needs to be used to activate this product version otherwise it will not be possible to use it.
If your Serv-U product maintenance is active, you can find your new license key generated on customer portal. Use this new license key to activate Serv-U 15.2.3 after installation.
Solarwinds strongly recommend that you upgrade to this version with the new licensing framework as older framework will not be supported in the future.
If you are upgrading from version 15.1.7 or older, increased password security and automatically converts existing MD5 passwords using a more secure algorithm when users connect for the first time after upgrade.
If an account is not used within 90 days of the upgrade, access will be restricted and the user will not be able to log in afterward. The administrator will be required to change their password.
