- @adamsilverstein: Refreshed the core WebP patch against trunk and started separate follow-up PRs for new featured added to the plugin since then.
- @shetheliving: Getting pretty close to wrapping up initial proposals for API to facilitate more accurate sizes #140 and Regenerate existing images #24; next steps will be more detailed design docs and core feature proposals. Research continues on Research: Impact of additional WebP images on upload #289 and Research: WebP compatibility #290 and we’ll draft a follow-up post about our findings and next steps.

- @codekraft: Looks like it’s supported in the most recent version
