The new WordPress 6.5 Block Bindings API is really great. I haven't seen many posts digging into why the custom source option is so powerful, so I wrote a short post on using it and Block Variations to make what amounts to a Dynamic Current Year block without having to actually make a block.
This is an excellent overview of WordPress Playground. Worth watching if you have any interest in ephemeral testing of themes & plugins as well as a new alternative to docker for development. I made the switch a couple of weeks ago to using wp-now for plugin and theme dev and it's been great (other than having to restart it every so often).
