Deterministic upgrades for stability

With the deterministic upgrades through versioned repositories feature, every AL2023 AMI by default is locked to a specific repository version. You can use deterministic upgrades to achieve greater consistency among package versions and updates. Each release, major or minor, includes a specific repository version.

New with AL2023, deterministic upgrading by default is enabled. This is an improvement over the manual, incremental method of locking that's used in AL2 and other earlier versions.

For more information, see Deterministic upgrades through versioned repositories on AL2023.
