+    This release is to tag Tempest for OpenStack 2025.2 release.
+    This release marks the start of 2025.2 release support in Tempest.
+    After this release, Tempest will support below OpenStack Releases:
+
+    * 2025.2
+    * 2025.1
+    * 2024.2
+    * 2024.1
+
+    Current development of Tempest is for OpenStack 2026.1 development
+    cycle. Every Tempest commit is also tested against master during
+    the 2026.1 cycle. However, this does not necessarily mean that using
+    Tempest as of this tag will work against a 2026.1 (or future release)
+    cloud.
+    To be on safe side, use this tag to test the OpenStack 2025.2 release.
