Upgrade and Repository Configuration

A detailed upgrade guide and repository configuration instructions are available below. Production environments should prioritize the Stable Repository to ensure maximum reliability.

Before upgrading, it is critical to create a system snapshot as a backup safeguard. This release introduces significant low-level architectural optimizations, and a snapshot ensures rapid recovery in case of unexpected issues.

For developers interested in testing unreleased features, preview builds from the master branch can be installed by modifying the repository URL: replace release with latest in the Stable Repository address.
