• @adamsilverstein: Discovered a library, jSquash, that brings image format encoding/decoding to the web. Tested a bit and oping to use it to enhance the core image blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. with modern image capabilities. If successful, would let us introduce AVIF support without depending on server-side support.
• @mehulkaklotar: Working on #563 for Performance Lab to change default WebP quality to 82; PR needs review.

  • https://github.com/WordPress/wordpress-develop/pull/3365
  • https://github.com/WordPress/wordpress-develop/pull/3178
• @tillkruess: Chatted with @johnjamesjacoby about adding a health check for the new wp_cache_supports() function to show which object caching features are supported/not supported but recommended. See https://github.com/WordPress/wordpress-develop/pull/3347. For example, get_multiple() is quite important. Any feedback on adding as a health check?
  • @spacedmonkey: Now have wp_cache_supports in core that we could use and wp_cache_supports( 'get_multiple') in all options. Instead of loading all options in one cache key, load each in their own cache key and all in single call.
