4. WG status update
   - EBML to be placed into 2-week WGLC upon posting of -07 version.
                   Dave Rice to post -07 version. Done.

   - work on Matroska and FFV1 issues
            - FFV1 some work resumed in September, some pull requests. still
            have a few issues still open.

5. https://github.com/FFmpeg/FFV1/issues
   - 4..5 identified issues. 3 for v1, 2 for v4.
   - believe that resolution is soon, and pull requests are good.
                - Dave Rice will post new document once 126 is merged. This has
                been done.

6. https://github.com/Matroska-Org/matroska-specification/issues
   - question from co-chair: why are "WEBM" issues in this document?
   - tags: "clarification" highest priority.
   - tag: codec mapping, mixed bag of priorities
   - tag: format addition, lowest priority.
   - codec mapping into it's own document?
   - one document per codec:  avc, hevc, vp9, opus, ac3, dts, (srt), (ssa),
   aac, (mp3), - "WebM" encryption elements are in still on common, but WebM
   was a fork of Matroska.
      Want to reserve ElementIds that are used in WebM to be reserved in
      Matroska. These values should be reserved in Matroska.

    re: #154, also in pull request #256, and also in an ITU document.
            - can be closed?
         re: #56, close it? leave it? lack of memory of what the issue was. 
         Closed. re: #43 closed as duplicate of ebml issue.
    re: #242, related to pull request #100, taken by Moritz.
    re: #234, move Control Track definitions to an appendix (Steve)

7. Any other Business.
   - IANA considerations for reserved values.
     --> WebM encryption values will need a longer discussion.
