+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
+
+## [1.2.2]
+### Added
+- SingleSlotReelsSpinSystem settings now expose `slotStopDelay` to pause between individual slot stops within a column while `reelStopDelay` continues to pace the first slot in each column, enabling layered timing without manual timers.
+- HoldAndWin stories expose `slotStopDelay` as a dedicated control to preview staggered slot timing.
+- HoldAndWin stories configure fractional steps for all numeric controls to enable fine-grained tuning during demos.
+- Added a stub `MaskingSystem` and wired it into Reels spin stories to prepare future masking orchestration work.
+- Introduced `BlurSymbolsSystem` to centralise blur orchestration for reels symbols.
+- Added dedicated Storybook demos for `MaskingSystem` and `BlurSymbolsSystem`, now mirroring the reel spin setup while piping Storybook controls through each system's `setSettings` method for live configuration tweaks.
+
+### Changed
+- Reels reel states no longer toggle blur directly; `ReelsSpinSystem` marks blur intent while `BlurSymbolsSystem` applies filters.
+- `BlurSymbolsSystem` removes cached filter areas, zeroes padding, and supports runtime velocity/kernel/offset configuration through `setSettings`.
+- `MaskingSystem` exposes an `enabled` flag so Storybook demos and games can disable masking without removing the system from st
+ates.
+
+### Fixed
+- SingleSlotReelsSpinSystem trims transient slot symbols and collapses each delayed reel to its landed symbol so duplicates cannot appear when `slotStopDelay` is enabled.
+- Column stop scheduling now respects `reelStopDelay` for the first slot in each column even while previous columns finish their queued slots, keeping staggered visuals aligned across reels.
+- Reel symbols remain visible when blur and masking are enabled together by removing conflicting bitmap caching from the blur toggle.
+- Motion blur applied to masked reel symbols now clips to the mask bounds so blur streaks no longer extend beyond the masked area.
+
+## [1.2.1] - 2025-10-20
+### Added
+- Story: DoubleHoldAndWinStory showing two HoldAndWinMachine instances stacked vertically, each with different initMap/screenMap.
+
+### Changed
+- HoldAndWin stories: scaled all MachineContainer instances to 0.5 (half size). In DoubleHoldAndWinStory both containers are scaled; spacing uses containerTop.height and respects scale. centerView alignment remains correct.
+
+## [1.2.0] - 2025-10-20
+### Added
+- Introduced HoldAndWin machine scaffold and Storybook story (features/HoldAndWin).
+- Single-slot reels support:
+  - SingleSlotReelsSpinSystem
+  - SingleSlotReel
+- Hold-and-win demo assets and manifest:
+  - configs/slotMachine.json
+  - symbols, anticipation, winline assets, bitmap fonts, textures
+- Auto-trigger spin in HoldAndWin story with generated screenMap and applied spin settings.
+
+### Changed
+- ReelsSpinSystem: support preventReelsSpin map to disable start/stop for selected reels; skip prevented reels in the spin flow.
+- ReelsMachine: integrate new maps/behavior for single-slot reels and preventReelsSpin handling.
+- Reel: adjustments to support single-slot behavior.
+- createScreenInputMap: generate maps aligned with the new HoldAndWin config.
+- SlotMachineConfig: extended with properties required by HoldAndWin and updated spinning behavior.
+- index.ts: export newly added modules.
+- ReelsSpinSystem story: updated with example demonstrating disabled first/last reels.
+
+## [1.1.23] - 2025-10-20
+### Added
+- Initialize CHANGELOG for the current branch.
+
+### Changed
