LocalStack Switches to Calendar Versioning
Blog post from LocalStack
LocalStack is transitioning from semantic versioning to calendar versioning starting with its March 2026 release, adopting a new format where version numbers are denoted by the year, month, and a patch number (e.g., 2026.03.0). This change, which affects products like LocalStack for AWS, Snowflake, Azure, and others, aims to provide more meaningful information as the semantic version numbers no longer effectively communicate the significance of updates. The new format aligns with LocalStack's monthly release cadence, allowing users to easily identify the release date from the version number. While the versioning system changes, the functionality of LocalStack remains the same, and only minor adjustments are needed in updating Docker setups or CI pipelines to accommodate the new version tags. Each product will manage its patch numbers independently, and "latest" tagged Docker images will continue to point to the most recent release.
