-### Command Palette Ahead-of-Time (AOT) readiness
+### Mouse Utilities
 
- - We’ve made foundational changes to prepare the Command Palette for future Ahead-of-Time (AOT) publishing. This includes replacing the calculator library with ExprTk, improving COM object handling, refining Win32 interop, and correcting trimming behavior—all to ensure compatibility, performance, and reliability under AOT constraints. All first-party extensions are now AOT-compatible. These improvements lay the groundwork for publishing Command Palette as an AOT application in the next release.
- - Special thanks to [@Sergio0694](https://github.com/Sergio0694) for guidance on making COM APIs AOT-compatible, [@jtschuster](https://github.com/jtschuster) for fixing COM object handling, [@ArashPartow](https://github.com/ArashPartow) from ExprTk for integration suggestions, and [@tian-lt](https://github.com/tian-lt) from the Windows Calculator team for valuable suggestion throughout the migration journey and review.
- - As part of the upcoming release, we’re also enabling AOT compatibility for key dependencies, including markdown rendering, Adaptive Cards, internal logging and telemetry library, and the core Command Palette UX.
-
-### FancyZones
-
- - Fixed DPI-scaling issues to ensure FancyZones Editor displays crisply on high-resolution monitors. Thanks [@HO-COOH](https://github.com/HO-COOH)! This inspired us a broader review across other PowerToys modules, leading to DPI display optimizations in Awake, Color Picker, PowerAccent, and more.
-
-### File Explorer add-ons
-
- - Fixed potential failures in PDF previewer and thumbnail generation, improving reliability when browsing PDF files. Thanks [@mohiuddin-khan-shiam](https://github.com/mohiuddin-khan-shiam)!  
- - Prevented Monaco Preview Handler crash when opening UTF-8-BOM text files.  
-
-### Hosts File Editor
-
- - Added an in-app *“Learn more”* link to warning dialogs for quick guidance. Thanks [@PesBandi](https://github.com/PesBandi)!  
-
-### Mouse Without Borders
-
- - Fixed firewall rule so MWB now accepts connections from IPs outside your local subnet.
- - Cleaned legacy logs to reduce disk usage and noise.  
+ - Added a new spotlight highlighting mode that creates a large transparent circle around your cursor with a backdrop effect, providing an alternative to the traditional circle highlight. Perfect for presentations where you want to focus attention on a specific area while dimming the rest of the screen.
 
 ### Peek
 
- - Updated QOI reader so 3-channel QOI images preview correctly in Peek and File Explorer. Thanks [@mbartlett21](https://github.com/mbartlett21)!  
- - Added codec detection with a clear warning when a video can’t be previewed, along with a link to the Microsoft Store to download the required codec.
+ - Added preview and thumbnail support for Binary G-code (.bgcode) files used in 3D printing. You can now see embedded thumbnails and preview these compressed 3D printing files directly in Peek and File Explorer. Thanks [@pedrolamas](https://github.com/pedrolamas)!
 
-### PowerRename
+### Quick Accent
 
- - Added support for $YY-$MM-$DD in ModificationTime and AccessTime to enable flexible date-based renaming.
-
-### PowerToys Run
-
- - Suppressed error UI for known WPF-related crashes to reduce user confusion, while retaining diagnostic logging for analysis. This targets COMException 0xD0000701 and 0x80263001 caused by temporary DWM unavailability.
-
-### Registry Preview
-
- - Added "Extended data preview" via magnifier icon and context menu in the Data Grid, enabled easier inspection of complex registry types like REG_BINARY, REG_EXPAND_SZ, and REG_MULTI_SZ, etc. Thanks [@htcfreek](https://github.com/htcfreek)! 
- - Improved file-saving experience in Registry Preview by aligning with Notepad-like behavior, enhancing user prompts, error handling, and preventing crashes during unsaved or interrupted actions. Thanks [@htcfreek](https://github.com/htcfreek)!  
+ - Added Vietnamese language support to Quick Accent, mappings for Vietnamese vowels (a, e, i, o, u, y) and the letter d. Thanks [@octastylos-pseudodipteros](https://github.com/octastylos-pseudodipteros)!
 
 ### Settings
 
- - Added an option to hide or show the PowerToys system tray icon. Thanks [@BLM16](https://github.com/BLM16)!
- - Improved settings to show progress while a bug report package is being generated.
-
-### Workspaces
-
- - Stored Workspaces icons in user AppData to ensure profile portability and prevent loss during temporary folder cleanup.
- - Enabled capture and launch of PWAs on non-default Edge or Chrome profiles, ensuring consistent behavior during creation and execution.
+ - Completely redesigned the Settings dashboard with a modern card-based layout featuring organized sections for quick actions and shortcuts overview, replacing the old module list.
+ - Rewrote setting descriptions to be more concise and follow Windows writing style guidelines, making them easier to understand.
+ - Improved formatting and readability of release notes in the "What's New" section with better typography and spacing.
+ - Added missing deep link support for various settings pages (Peek, Quick Accent, PowerToys Run, etc.) so you can jump directly to specific settings.
+ - Resolved an issue where the settings page header would drift away from its position when resizing the settings window.
+ - Resolved a settings crash related to incompatible property names in ZoomIt configuration.

+ - Added detailed step-by-step instructions for first-time developers building the Command Palette module, including prerequisites and Visual Studio setup guidance. Thanks [@chatasweetie](https://github.com/chatasweetie)!
+ - **Fixed Broken SDK Link**: Corrected a broken markdown link in the Command Palette SDK README that was pointing to an incorrect directory path. Thanks [@ChrisGuzak](https://github.com/ChrisGuzak)!
+ - Added documentation for the "Open With Cursor" plugin that enables opening Visual Studio and VS Code recent files using Cursor AI. Thanks [@VictorNoxx](https://github.com/VictorNoxx)!
+ - Added documentation for two new community plugins - Hotkeys plugin for creating custom keyboard shortcuts, and RandomGen plugin for generating random data like passwords, colors, and placeholder text. Thanks [@ruslanlap](https://github.com/ruslanlap)!
 
 ### Development
 
- - Updated .NET libraries to 9.0.6 for performance and security. Thanks [@snickler](https://github.com/snickler)!  
- - Updated WinAppSDK to 1.7.2 for better stability and Windows support.  
- - Introduced a one-step local build script that generates a signed installer, enhancing developer productivity.
- - Generated portable PDBs so cross-platform debuggers can read symbol files, improving debugging experience in VSCode and other tools.
- - Simplified WinGet configuration files by using the [Microsoft.Windows.Settings](https://www.powershellgallery.com/packages/Microsoft.Windows.Settings) module to enable Developer Mode. Thanks [@mdanish-kh](https://github.com/mdanish-kh)! 
- - Adjusted build scripts for the latest Az.Accounts module to keep CI green.
- - Streamlined release pipeline by removing hard-coded telemetry version numbers, and unified Command Palette versioning with Windows Terminal's versioning method for consistent updates.

+ - Updated .NET libraries to 9.0.8 for performance and security. Thanks [@snickler](https://github.com/snickler)!
+ - Updated the spell check system to version 0.0.25 with better GitHub integration and SARIF reporting, plus fixed numerous spelling errors throughout the codebase including property names and documentation. Thanks [@jsoref](https://github.com/jsoref)!
+ - Cleaned up spelling check configuration to eliminate false positives and excessive noise that was appearing in every pull request, making the development process smoother.
+ - Replaced NuGet feed with Azure Artifacts for better package management.
+ - Implemented configurable UI test pipeline that can use pre-built official releases instead of building everything from scratch, reducing test execution time from 2+ hours.
+ - Replaced brittle pixel-by-pixel image comparison with perceptual hash (pHash) technology that's more robust to minor rendering differences - no more test failures due to anti-aliasing or compression artifacts.
+ - Reduced CI/fuzzing/UI test timeouts from 4 hours to 90 minutes, dramatically improving developer feedback loops and preventing long waits when builds get stuck.
+ - Standardized test project naming across the entire codebase and improved pipeline result identification by adding platform/install mode context to test run titles. Thanks [@khmyznikov](https://github.com/khmyznikov)!
