# Versioning The Discourse charm has transitioned from semantic versioning to calendar-based versioning to align with the upstream Discourse project’s new versioning strategy. ## Historical versioning (semantic versioning) **Last Release:** [Revision 227](https://github.com/canonical/discourse-k8s-operator/releases/tag/rev227) - Version 3.5.3 The Discourse charm previously followed semantic versioning (SemVer) format `MAJOR.MINOR.PATCH`, with the final release using this format being version 3.5.3 published as revision 227. ## Current versioning (calendar-based) **New Format:** `YYYY.MM.PATCH-BRANCH` Starting with releases after revision 227, the Discourse charm follows the new calendar-based versioning strategy adopted by the upstream Discourse project. This format includes: - **YYYY**: Year (e.g., 2025) - **MM**: Month (e.g., 12 for December) - **PATCH**: Patch version for the month - **BRANCH**: Branch identifier (e.g., `latest`, `beta`) **Example:** `2025.12.0-latest` The Discourse charm will track the `-latest` branch of the upstream Discourse releases, providing the most current stable version within each monthly release [cycle.Co](http://cycle.Co) ## Reference For more information about the new versioning strategy, see the [RFC: A new versioning strategy for Discourse](https://meta.discourse.org/t/rfc-a-new-versioning-strategy-for-discourse/383536).
