Version 3.4.0
Release date: Mar 04, 2026
New features:
New OS support: Ubuntu 24.04
API key protection:
- Strengthening security by protecting users' API key (if created) in the database using SHA256 hashing. Then actual API key value could not be retrieved back for good.
- By default, this feature is not enabled for backward compatibility. Administrators need to opt-in by enabling that. Expecting to see the following UI notification poped up upon signed in:
- Warning: Once enabled, administrators cannot turn back the feature for security enforcement. Before switching on this feature, it's strongly recommended to backup your users' API key in a secured vault / secrets manager.
- When this feature is enabled, API key will be hashed out in the database, and no one, including administrators, will be able to see actual API key value anywhere in the product.
- In case API key is lost or not remembered, then administrators must re-create a new one. The new one will be displayed for only one time on the UI.
