 In this release, we focused on new features, stability, optimization improvements, and automation.
 
+For an in-depth look at the latest changes, visit the [release blog](https://aka.ms/powertoys-releaseblog).
+
 **✨Highlights**
 
- - PowerToys settings debuts a modern, card-based dashboard with clearer descriptions and faster navigation for a streamlined user experience.
- - Command Palette had over 99 issues resolved, including bringing back Clipboard History, adding context menu shortcuts, pinning favorite apps, and supporting history in Run.
- - Command Palette reduced its startup memory usage by ~15%, load time by ~40%, built-in extensions loading time by ~70%, and installation size by ~55%—all due to using the full Ahead-of-Time (AOT) compilation mode in Windows App SDK.
- - Peek now supports instant previews and embedded thumbnails for Binary G-code (.bgcode) 3D printing files, making it easy to inspect models at a glance. Thanks [@pedrolamas](https://github.com/pedrolamas)!
- - Mouse Utilities introduces a new spotlight highlighting mode that dims the screen and draws attention to your cursor, perfect for presentations.
- - Test coverage improvements for multiple PowerToys modules including Command Palette, Advanced Paste, Peek, Text Extractor, and PowerRename — ensuring better reliability and quality, with over 600 new unit tests (mostly for Command Palette) and doubled UI automation coverage.
+ - PowerToys Settings added a Settings search with fuzzy matching, suggestions, a results page, and UX polish to make finding options faster.
+ - A comprehensive hotkey conflict detection system was introduced in Settings to surface and help resolve conflicting shortcuts. Note that the default hotkey settings (Win+Ctrl+Shift+T, Win+Ctrl+V, Win+Ctrl+T, Win+Shift+T) may overlap with existing Windows system shortcuts. This is expected. You can resolve the conflict by assigning different hotkeys.
+ - Mouse Utilities added a “Gliding cursor” accessibility feature to Mouse Pointer Crosshairs for single‑button cursor movement and clicking. Thanks [@mikehall-ms](https://github.com/mikehall-ms)!
+ - The installer was upgraded to WiX 5 after WiX 3 reached end-of-life; this move improved installer security, reliability, and community support.
+ - Tons of bug fixes and improvements for Command Palette, including visual updates and new support for filters on ListPages (handy for extension developers).
+ - Hosts Editor now has a “No leading spaces” option so active host entries can start at column 0 even if others are disabled. Thanks [@mohammed-saalim](https://github.com/mohammed-saalim)!
+ - Context menu registration was moved from the installer to runtime to avoid loading disabled modules (runtime registrations).
+ - Quick Accent now supports Maltese, and frequently used accents appear first (and are remembered across sessions). Thanks [@rovercoder](https://github.com/rovercoder)! [@davidegiacometti](https://github.com/davidegiacometti)!
+
+### Always On Top
+
+ - Fixed the border hover cursor so it shows the arrow instead of the wait cursor. Thanks [@davidegiacometti](https://github.com/davidegiacometti)!

- - Improved extension disposal with better error handling to prevent crashes. Thanks [@jiripolasek](https://github.com/jiripolasek)!
- - Improved stability by fixing a UI threading issue when loading more results, preventing possible crashes and ensuring the loading state resets if loading fails. Thanks [@jiripolasek](https://github.com/jiripolasek)!
- - Enhanced icon loading stability with better exception handling. Thanks [@jiripolasek](https://github.com/jiripolasek)!
- - Added thread safety to recent commands to prevent crashes. Thanks [@MaoShengelia](https://github.com/MaoShengelia)!
- - Fixed acrylic (frosted glass) system backdrop display issues by ensuring proper UI thread handling. Thanks [@jiripolasek](https://github.com/jiripolasek)!
+ - Applied single-click activation only to pointer input; keyboard always activates immediately. Thanks [@jiripolasek](https://github.com/jiripolasek)!
+ - Let context menus open at the cursor by removing window-bound constraints. Thanks [@jiripolasek](https://github.com/jiripolasek)!
+ - Made error messages clearer with timestamps, HRESULTs, and full details for easier diagnosis. Thanks [@jiripolasek](https://github.com/jiripolasek)!

- - 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.

- - 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)!
- - Added comprehensive UI test suites for multiple PowerToys modules including Command Palette, Advanced Paste, Peek, Text Extractor, and PowerRename - ensuring better reliability and quality.
- - Enhanced UI test automation with command-line argument support, better session management, and improved element location methods using pattern matching to avoid failures from minor differences in exact matches.
+ - Excluded test and coverage DLLs from BinSkim scans to cut false positives and speed up security analysis.
+ - Simplified NOTICE maintenance by removing version numbers and filtering out Microsoft/System packages.
+ - Improved NuGet dependency validation to prevent package downgrades and catch issues during restore.
