Hi! Nick and I are about to post the agenda; apologies for it being late.  A couple of things to note our WG I-Ds and the upcoming session:

1) -mls-extensions completed WGLC. There are 4 open issues:
https://github.com/mlswg/mls-extensions/issues
There are now PRs for two. Note that we are pausing for implementation experience before we progress this I-D out of the WG.

2) -mls-combiner appears to be pretty stable. The authors addressed John’s comments and will work on Brendan’s new comments. It would be helpful if others also read the I-D. When I ask who has read it during WG status it would be *great* if like 5 new people would raise their hands (after reading it of course).

3) -mls-pq-ciphersuites we will get an update on during the session.

4) -mls-targeted-messages was recently adopted (and soon to be submitted).

5) -mls-partial was adopted in August, but there have been no updates.

6) The reading list for this non-WG MLS I-Ds is pretty long, but please do have a read so that we can have informed discussions:

# Distributed MLS
