 ## [Unreleased]
 
+## [1.1.4.1] - 2026-06-13
+
+### Changed
+
+- Widen the `containers` version bound from `<0.8` to `<0.9`
+  to allow `containers` 0.8, which ships with GHC 9.14.
+- Switch dependency version bounds from the PVP caret operator (`^>=`)
+  to explicit `>=x && <y` ranges.
+  So that Renovate can recognize and update them.
+
 ## [1.1.4.0] - 2026-06-13
