+## Changes in 1.5.4
+
+### Bug fixes
+
+- **Roofline legend placement**: Roofline plot legends now use fixed
+  coordinates instead of dynamic placement, preventing the legend from
+  overlapping data points or being rendered off-canvas (#546).
+- **Subcluster usage tab labels**: Subcluster names in the status dashboard
+  usage tabs are no longer force-capitalized; the original cluster-defined
+  casing is preserved.
+- **NodeListRow host filter**: The running-jobs query in the node list row now
+  filters by exact node hostname (`eq`) instead of substring match
+  (`contains`), avoiding incorrect matches when one hostname is a prefix of
+  another.
+
+### Dependencies
+
+- **Go module upgrades**: Refreshed Go module dependencies to their latest
+  compatible versions.
