###  Milestone review:

   * Previous status: Jerome is now able to focus on FFV1-v4, since we've published FFV1.
       **ACTION** Spencer to send e-mail to DISPATCH when we submit a (small) update. We should wait until we have a bit more text, or bigger issues, to publish as a draft.


   * Are we ready to submit a working group draft for EBML updates (errata plus additions) yet? (https://github.com/ietf-wg-cellar/ebml-specification/tree/corrections-doc)
       * we can still wait for more feedback/bigger changes before submitting anything - ETA is "after we get Matroska out, so we know everything Matroska needs will be covered"
       * also have some implementation/experience reports.
   * Discussion about what is an Internet Standard.
       * it is actually quite an old format, a lot of implementations.
           * but for many implementations, there will be no updates, but the current files play just fine.

### Matroska issues - Discussion on the call
   * merged a few pull requests
   * merged/rewrote the time work, defined different ticks for each time base
       * was trying to sample/presized timestamps.  Could work, but would never be backwards compatible.  So, removed that part, and simplified the result.
           * got some comments, but it is ready.
           * some bugs, but already fixed.
   * https://github.com/ietf-wg-cellar/matroska-specification/pull/577 more review needed.
   * https://github.com/ietf-wg-cellar/matroska-specification/pull/578 generated IANA Considerations.
       * does not generate unassigned for gaps
       * "Any values not mentioned in this table are unassigned"
   * https://github.com/ietf-wg-cellar/matroska-specification/pull/521 needs to be merged (timebase)
   * https://github.com/ietf-wg-cellar/matroska-specification/issues?q=is%3Aopen+is%3Aissue+project%3Aietf-wg-cellar%2Fmatroska-specification%2F1+-label%3Amatroska-v5+-label%3A%22control+track%22   this is the list of things that need to be fixed before the document can be finished.
       * also: PRs: https://github.com/ietf-wg-cellar/matroska-specification/pulls?q=is%3Apr+is%3Aopen+project%3Aietf-wg-cellar%2Fmatroska-specification%2F1+-label%3Amatroska-v5+-label%3A%22control+track%22+sort%3Acreated-desc

### FLAC issues - Discussion on the call

   * Martijn will merge some items and close some dead issues and post a new version soon.

### FFV1 v4 issues - Discussion on the call
