+## [1.3.4] - 2026-07-29
+
+### Fixed
+
+- Prevented Niri startup CPU-budget failures on large, split configurations.
+- Prevented Hyprland refreshes from exhausting the callback CPU budget and
+  leaving the shortcut snapshot stuck in its loading state.
+- Restored editing for literal native-Lua binds after the optimized refresh.
+
+### Changed
+
+- Skipped the hidden-bind scan for files without Keymap hidden sentinels.
+- Skipped character-level parsing for included files that cannot contain binds
+  or nested includes.
+- Added fast paths for common Hyprland Lua literals and dispatcher expressions.
+- Switched active Hyprland source validation to exact snippet comparison while
+  retaining legacy fingerprints for hidden blocks and older snapshots.
+
+### Tests
+
+- Added a 127-bind split-config regression with a large unrelated include.
+- Added a split native-Lua regression covering invalid Hyprland JSON fallback,
+  callback instruction budgets, and editable source provenance.
