[PNG] Cancel upcoming meeting?

Hello everyone,

We have a meeting scheduled for Monday, Apr 28th.
But I think we're blocked and don't have anything to discuss.

We approved the transition of Third Edition to Proposed Recommendation. It
will now wait for a bit of W3C approval and finishing up the
exemption period. Then it will go through a longer W3C approval to become a
recommendation.

We also established what we want to work on for Fourth Edition:

   - To be added:
      - Gain maps / gain curves / T.35 / rWTm are in, but waiting for the
      other spec to finish.
      - Negative cHRM values
   - Not added:
      - No update to spec wording for parallel decoding, but we do want to
      implement the pigz method and investigate the chunk method (perhaps for
      Fifth Edition).
   - No update to the spec for alternative compression methods. We will
      also investigate this and revisit for Fifth Edition if it is warranted.

This marks Fourth Edition as a fairly small update. But I imagine there
will be lots of work on those investigations.

We decided to not start Fourth Edition work (other than deciding what we'll
want to work on) until Third Edition is complete. So I think there is
nothing left to discuss for now.

If you all have topics you want to bring up, let us know. Otherwise, I
think we can cancel.
