 ## [Unreleased]
 
+## [0.8.4] - 2026-09-09
+
+### Fixed
+
+- Enable the native Dirgo predictor on supported PowerShell releases newer than 7.4, including PowerShell 7.5 and 7.6, instead of rejecting every minor version other than 7.4.
+- Exercise the native prediction path on any PowerShell 7.4+ Windows runner so future LTS upgrades cannot silently disable suggestions.
+- Keep PowerShell profile startup quiet when PSReadLine refuses prediction UI settings for redirected or non-interactive output; the registered predictor and `Ctrl+F` fallback remain available.
