# Release notes

> CalVer release notes for Banking OS APIs and Banking OS Connectors.

Banking OS publishes release notes for two release streams: the Banking OS APIs (the unified API specifications) and the Banking OS Connectors. Both streams use calendar versioning (CalVer), so each version name starts with the year and month of the release, for example `2026.08`. Patch releases add a third segment, for example `2026.06.03`. A long-term support (LTS) release adds the `-LTS` suffix, for example `2026.09-LTS`.

Each release page groups entries by type. Each entry names the affected API or connector and its version.
