Apollo has announced the end of support for Router v1.x, including version v1.61.x LTS, and Federation v2.9, effective March 31, 2026, as part of its updated Long-Term Support (LTS) policy aimed at providing a predictable and stable release cycle. Users operating on these versions are encouraged to upgrade to Router v2.10 and Federation v2.12, which were released on December 12, 2025, as the new LTS versions that will receive critical security patches and reliability updates until September 2026. The updated LTS policy involves annual major Router releases with 12 months of active development, and recurring LTS releases every six months, each supported for nine months with an additional three months for Premier Support customers. Apollo emphasizes the importance of upgrading to minimize operational risks and assures continued support during the transition to ensure powerful and future-proof API infrastructure.
