 - [Portunus](https://github.com/majewsky/portunus) has been updated to major version 2.
   This version of Portunus supports strong password hashes, but the legacy hash SHA-256 is also still supported to ensure a smooth migration of existing user accounts.
   After upgrading, follow the instructions on the [upstream release notes](https://github.com/majewsky/portunus/releases/tag/v2.0.0) to upgrade all user accounts to strong password hashes.
