WordPress 6.0.2 now parsed
WordPress 6.0.2, a security and maintenance release, was made available on 30th August 2022. It has now been parsed on core.wp-a2z.org.
Notes
- The Post Content block is intended for use in Templates and Template parts.
- It can also be used in the Post Template block within the Query Loop block.
Recursion detection and prevention
- The Post Content block is one of those blocks that can go recursive.
- This was a known issue in Gutenberg 9.x
- I created a Post Content block automatically and it all went tits up with Gutenberg 10.0.0
- I thought it had been fixed.
- I must have been mistaken.
- I’ve updated the issue WordPress/gutenberg#26923.
- The issue is still open, though work has been done to improve the behaviour.
- Gutenberg does now contain some recursion detection logic.
Within the block editor
If used in normal content the block will display a message
