Below is an update to the IRIS release calendar for 2026 and an early look at the planned changes for 2027. The key takeaway for 2026 is that maintenance release numbering will differ slightly from prior years.
2026: IRIS 2026.1 maintenance release numbering
- July 2026: first maintenance release for IRIS 2026.1 (planned version: 2026.1.4)
- October 2026: next maintenance release (planned version: 2026.1.5)
- February 2027: following maintenance release (planned version: 2026.1.6)
This numbering change prepares us for the expanded maintenance cadence planned for 2027.
