+25.5.1 (2025-05-22)
+-------------------
+
+A smaller release with some big features. We now have the capability to select a
+sub-area of a domain for analysis. This is useful both for looking at small
+parts of a large (perhaps global) domain, as well as for trimming off boundaries
+that may contain numerical artifacts.
+
+We also follow up on the last release by bringing multiple model support to time
+series and vertical profile plots.
