[PNG] Cancel upcoming meeting?

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>)
