- @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.
