Blockers 🙅‍♀️

• __experimentalInserterMenuExtension to __unstableInserterMenuExtension broke WPCOM-specific code in ETK and wpcom-block-editor, causing the editor and wp-admin to WSOD 💥. This is blocking the release of v10.7.0-rc.1 to simple edge sites.

  • Introduced by: Mark the inserter slot as unstable WordPress/gutenberg#31417
  • Fix is here: [ETK/wpcom-block-editor] Use __unstable InserterMenuExtension if available, fallback to __experimental #53131

• Premium Content block is breaking. Fix: Premium Content Block: Update to useBlockProps jetpack#19844.

This has been fixed in the PR and merged, but is yet to be deployed to WPCOA/WoA. Even though we could get it on simple sites now, it's best to wait until the next Jetpack release on June 1st for the new JP release or people that upgrade to WoA will get invalidation errors with the Premium Content block. More details in this thread: p1621442044054200-slack-CBG1CP4EN.

• Disable features and add sticker toggles (p9oQ9f-vj-p2#comment-920, p1620735562081300-slack-C7YPUHBB2):

  • Block Widgets (D50432-code)
  • Navigation Block (p9oQ9f-vj-p2#comment-928)
  • Template Editing (D61453-code, D61455-code)

• Necessary JP blocks updates (p1620817101206900-slack-CBTN58FTJ)

  • Blocks: switch away from __experimentalBlock to useBlockProps jetpack#18864
  • Remove the block wrapper component WordPress/gutenberg#31419

Transfered from previous release(s)

• wp-components's index.js is broken by the WPCOM minifier. There's a hotfix (D61090-code, D61091-code) applied in the RC1 that allowed us to ship it to simple sites for now. We still don't know what exactly in v10.6.0 RC1 caused this. We might need to be hotfixing on simple sites while we don't have a perm. solution. See: p1620321684463200-slack-C02A41GCS and p1620319065221200-slack-C4GAP2RHD.

  • Generate minified .min.js and unminified .js files for GB js entry points when building WordPress/gutenberg#31732

• P2 inline comments broken (and potentially other P2-related issues). Reported here: p1620327615008700-slack-C025Q5RK2 cc @johngodley (P2s have been pinned to 10.5.4 for now, see: p1621258202222400/1620838719.129600-slack-C7YPUHBB2, which makes this issue not a blocker for now).

• Classic: Infinite content duplication loop when wrapping with anchor tag #29338

  • Reported in: p1613735197155300/1613458151.107400-slack-CBTN58FTJ
