ScyllaDB Version Support¶

Supported Versions¶

Version Numbering¶

ScyllaDB follows the MAJOR.MINOR.PATCH semantic versioning:

• MAJOR versions contain significant changes in the product and may introduce incompatible API changes.

• MINOR versions introduce new features and improvements in a backward-compatible manner.

• PATCH versions have backward-compatible bug fixes.

LTS vs. Feature Releases¶

Long-Term Support (LTS)

• Released approximately once a year.

• Two last LTS versions are supported.

Feature releases:

• 2-4 feature releases per year.

You can only use LTS releases (upgrading to the latest patch release for the greatest stability) or follow the feature and LTS releases for the latest feature set.
