 Our [prioritized roadmap][roadmap] of features and utilities that the core team is focusing on.
 
-### 0.90 - March 2025 Update
+### 0.91 - May 2025 Update
 
 In this release, we focused on new features, stability, and automation.
 
 **✨Highlights**
 
-![Gif for Command Palette](doc/images/overview/CmdPal_Hero.gif)
+ - We focused on greatly improving Command Palette's performance and fixing a large amount of bugs. Some new features we've added are:
+ - Added the ability for Command Palette to search any file using a fallback command.
+ - Added the ability to make the Command Palette global hotkey a low-level keyboard hook.
+ - Added open URL fallback command for the WebSearch extension, enabling users to directly open URLs in the browser from Command Palette.
+ - You can now define custom formats in the Date and Time plugins of PT Run and Command Palette. Thanks [@htcfreek](https://github.com/htcfreek)!
 
-- New module: Command Palette ("CmdPal") -  Created as the evolution of PowerToys Run with extensibility at the forefront, Command Palette is a quick launcher with a richer display and additional capabilities without sacrificing performance, allowing you to start anything with the shortcut **Win+Alt+Space**! Thanks [@zadjii-msft](https://github.com/zadjii-msft), [@niels9001](https://github.com/niels9001), [@michael-hawker](https://github.com/michael-hawker), [@joadoumie](https://github.com/joadoumie), [@plante-msft](https://github.com/plante-msft), [@ethanfangg](https://github.com/ethanfangg) and [@krschau](https://github.com/krschau)!
- - Enhanced the Color Picker by switching from WPF UI to .NET WPF, resulting in improved themes and visual consistency across different modes. Thanks [@mantaionut](https://github.com/mantaionut)! Thanks [@Jay-o-Way](https://github.com/Jay-o-Way) and [@niels9001](https://github.com/niels9001) for helping with the review!
- - Added the ability to delete files directly from Peek, enhancing file management efficiency. Thanks [@daverayment](https://github.com/daverayment) and thanks [@htcfreek](https://github.com/htcfreek) for the review!
- - Added support for variables in template filenames, enabling dynamic elements like date components and environment variables for enhanced customization in New+. Thanks [@cgaarden](https://github.com/cgaarden)!
+### Advanced Paste
+
+ - Fixed an issue where Advanced Paste failed to create the OCR engine for certain English language tags (e.g., en-CA) by initializing the OCR engine with the user profile language. Thanks [@cryolithic](https://github.com/cryolithic)!
 
 ### Color Picker
 
- - Replaced WPF UI with .NET WPF for the Color Picker, enhancing compatibility and improving theme support. Thanks [@mantaionut](https://github.com/mantaionut)! Thanks [@Jay-o-Way](https://github.com/Jay-o-Way) and [@niels9001](https://github.com/niels9001) for helping with the review!
+ - Fixed an issue where a resource leak caused hangs or crashes by properly disposing of the Graphics object. Thanks [@dcog989](https://github.com/dcog989)!
+ - Fixed an issue where Color Picker exited on Backspace keypress by ensuring it only closes when focused and aligning Escape/Backspace behavior. Thanks [@PesBandi](https://github.com/PesBandi)!
+ - Added support for Oklab and Oklch color formats in Color Picker. Thanks [@lemonyte](https://github.com/lemonyte)!
+
+### Command Not Found
+
+ - Updated the WinGet Command Not Found script to only enable the experimental features if they actually exist.
 
 ### Command Palette
 
-- Introduced the Windows Command Palette ("CmdPal"), the next iteration of PowerToys Run, designed with extensibility at its core. CmdPal includes features such as searching for installed apps, shell commands, files and WinGet package installation. This module aims to provide a more powerful and flexible launcher experience. Thanks [@zadjii-msft](https://github.com/zadjii-msft), [@niels9001](https://github.com/niels9001), [@michael-hawker](https://github.com/michael-hawker), [@joadoumie](https://github.com/joadoumie), [@plante-msft](https://github.com/plante-msft), and the whole team!
-
-### FancyZones
-
- - Fixed a bug where deleting a layout resulted in incorrect data being written to the JSON file.
- - Fixed a bug where layout hotkeys were displayed incorrectly, ensuring the hotkey list does not include invalid entries.
- - Fixed an issue where the "None" option was missing in the editor layout.
+ - Updated bug template to include Command Palette module.
+ - Fixed an issue where the toast window was not scaled for DPI, causing layout issues under display scaling.
+ - Fixed an issue where Up/Down keyboard navigation didn't move selection when caret was at position 0, and add continuous navigation like PT Run v1. Thanks [@davidegiacometti](https://github.com/davidegiacometti)!
+ - Updated the Time and Date extension code to simplify it and improve clarity.
+ - Fixed an issue where capitalization in the command causes failure when trying to go to the mouse pointer, resolved by adjusting the command to lowercase.
