Each release is named for the next calendar year and the month. For example, ODA SDK 2027.10 was released in October 2026, uses archive suffix _27.10, and comes from branch release/27.10. Monthly releases (X.1–X.12, with X.1 releasing in February) bring new features, API changes and fixes, but are not patched or updated: bugs are fixed in the next release. The last release of each year (X.12) is an LTS release, supported for two years with service packs (for example, 25.12SP2) about every six months. Service packs contain only security, stability, data-integrity and critical-performance fixes, with no new features or API changes.
