It adds support for High Dynamic Range (HDR), and adds Animated PNG to the official standard.

If you're one of my academic publishing folks: sadly, it's true. Due to a funder's unexpected decision to pull support, we've had to make the incredibly difficult decision to wind down PubPub over the next 18 months and regroup to figure out how to best serve our mission.

I'm sure I'll have more to say, but today I'm feeling both gratified and saddened by the overwhelmingly supportive responses to our announcement.

I urge you to learn from our mistakes: https://www.knowledgefutures.org/updates/2025-06-update/

I rarely subtoot, but when I do just to say: if an open source project that your commercial project depends on breaks something in your software stack, causing you trouble, no matter how much, that's your problem and your problem alone.

"The software is provided as is" is a part of OSS licenses for a reason, and unless we have a contract that says otherwise, I'm not part of your bloody "supply chain".
