 ## [Unreleased]
 
+## [1.1.4.0] - 2026-06-13
+
+### Added
+
+- `discardLogAction` export in `Himari.Logger`,
+  a `LogAction` that discards all log output,
+  useful for tests that should not write logs to the real terminal
+- `runSimpleNoLogEnv` export in `Himari.Env.Simple`,
+  a shorthand for `runSimpleEnvWith discardLogAction`
+  that runs a `SimpleEnv` action while discarding all log output
+- Re-export all public `time` modules that `Data.Time` itself does not re-export
+  in `Himari.SafePrelude`:
+  `Data.Time.Calendar.Easter`,
+  `Data.Time.Calendar.Julian`,
+  `Data.Time.Calendar.MonthDay`,
+  `Data.Time.Calendar.Month`,
+  `Data.Time.Calendar.OrdinalDate`,
+  `Data.Time.Calendar.Quarter`,
+  `Data.Time.Calendar.WeekDate`,
+  `Data.Time.Clock.POSIX`,
+  `Data.Time.Clock.System`,
+  `Data.Time.Clock.TAI`,
+  `Data.Time.Format.ISO8601`,
+  and register them in the `fourmolu.yaml` `reexports` setting
+
+### Changed
+
+- Relax `aeson` dependency upper bound from `^>=2.2.3.0` to `^>=2.2.3.0 || ^>=2.3.0.0`
+  to allow building against `aeson` 2.3.y.z
+
+### Fixed
+
+- Restructure the `fourmolu.yaml` `reexports` chain to match the module hierarchy
+  introduced with `Himari.SafePrelude` in 1.1.3.0:
+  re-exports that moved to `Himari.SafePrelude` are now registered under it
+  instead of `Himari.Prelude`,
+  and the previously missing `Data.Default` and `UnliftIO.Retry` entries are added
+
 ## [1.1.3.0] - 2026-05-30
