Hello everyone, We have a meeting on Monday. If we cancel, that will be 2 in a row. But we're in a bit of a holding pattern, I think. Is this right, Chris L? I believe our Call for Consensus has resulted in a Candidate Recommendation snapshot. I think our next step is to transition to Proposed Recommendation, then submit to W3C for Recommendation approval. If we have nothing to discuss, I suggest we cancel. We should start talking about Fourth Edition. But I'm hesitant to dig into it deeply until Third Edition is finalized. So for now, perhaps think about it / let it stew / comment on github issues. Two topics I think will make it into Fourth Edition: - Restart markers to allow parallel decoding (several <https://github.com/w3c/png/issues/60> github <https://github.com/w3c/png/issues/54> issues <https://github.com/w3c/png/issues/41>) - Compression other than deflate (github issue <https://github.com/w3c/png/issues/39>) - Existing images continue to work in existing decoders. Old decoders would not be able to decode new images. My understanding is this doesn't constitute a "break". One (maybe two) topic(s) with some pushback might not make it: - Gain maps (github issue <https://github.com/w3c/png/issues/380>) - Generic image data (github issue <https://github.com/w3c/png/issues/493>) One topic might, depending on timing: - dWLm, which I believe depends on ISO 22028-5. Has that been published? If so, it will probably make it in. (github issue <https://github.com/w3c/png/issues/390>)
