This is a tracking issue to provide a quick overview of the editor's remaining triaged tasks and is expected to evolve in the coming weeks as the 6.0 release proceeds, in the spirit of the similar issue used in the last release cycle.

What was found in the 6.0 walk-through and what currently exists in the project board is serving as the foundation.

🚨 Major blocking issues

✅ All good! Nothing is blocking the next Beta release.

⚠️ Must-haves before RC

Specific functionalities require the following issues, but they do not block or put at risk the whole release.

• Webfonts API: Move webfonts handling to internal only (not accessible) - WP 6.0 Stopgap #40472
• Layouts: Flex layout: Wrap multiple lines as default #39651
• Block placeholders: Apply duotone filter to placeholders for Site Logo & Post Featured Image blocks #40061

✨ Nice to have and feature polishing - Not for 6.0 anymore as time run out 🙅

• Block transforms: Keep width settings when transforming to container blocks (row, stack, group) #40059. Punted to 6.1. TL;DR; it's not a Gutenberg bug and it needs to be addressed conceptually.
• [Site Editor] Templates and Template Parts screens - Provide a way for users to add a description to custom templates. #36664
• Group block variations: Update Group Block description to apply for variations #40062
• Multi-Select: hide grouping controls for when selecting text only blocks #40063
• Multi-selection: List View: Consider hiding some of the ellipsis menus when mass selecting #40066
• Block placeholders: Improve placeholder for Post Content block #40074
• Styles sidebar: Global Styles variations: Refining hover animation #39700
• More granular multi-entity saving options for global style changes: Site Editor: Offer more granular information in multi-entity saving flow #29388
• Refine the global styles panel, the prominence, and placement items: Reviewing Global Styles main panel #38934
• Style variations: Add "Randomize" button #39629
• Duotone filter not rendering in some places #35331 🐛
• Elements: Add styles to the footer before the block is rendered #37728 🐛
