dgoulet:
  * Last week:
    - Work on prop224 tickets. We've postponed the IPv6 + Single onion service
      discussion until Montreal.
    - Spent some time debugging scheduler KIST issues which turned out to be
      more deeper issues within tor: #23709, #23710, #23711, #23712
    - Worked on ticket from the 032 milestone including review/triage/patches.
      Nothing big though, most of it was hs/sched related.
  * This week:
    - Continue the 032 milestone work. Some prop224 and scheduler stuff needs
      to be done for the stable.
    - I want to prep for the IPv6 hackfest in Montreal next week with teor.
      Many issues in the hidden service subsystem that I want to document
      properly before that.
    - Need some prep as well for the circuit building expiring logic for
      hidden service for which I want/need to sit down with Mike for this in
      Montreal (mostly related to #3733).

teor: (offline, leave this week)
  Last week:
    * finish off a bunch of experimental PrivCount features and bug fixes
    * review Shamir secret sharing proposal
    * prepare to travel to Montreal (so many bits of paper!)
    * I think there's some tor coding I forgot, too
  This week:
    * week off: rest, casual coding, enjoy Montreal

ahf:
    Last week:
        Sponsor 4:
        - Fixed Zstd regression in #23551
        Sponsor 8:
        - Roger found an issue with the HS we used to do our download test
          with. We fixed this using JavaScript to download the file in the
          browser and report back the results to the server.
        Release work:
        - Meeting with Isis and Nick about what needs to be done before the
          release.
        - Reviewed: #23691, #23690
    This week:
        - Roll 0.3.2.2-alpha together with Isis.
        - Prepare for Montreal meeting. Leaving on Friday (and will by in the
          air almost the entire day).
        - Finish Rust toy project.
        - Update the Sponsor 8 HS to allow the testers to specify their country
          when doing the testing.
        - Go over things I haven't gotten around to in the last week:
go over old
          bugs, end of month tasks

asn
  Last week:
  - Reviewed #23662 and #23603 for prop224. Worked on #23493.
  - Reviewed #23100.
  - Worked on #23672. Now ready for merge..
  - Did some more debugging on #21969 ("missing primary guard
    descriptors"). This bug is still alive and a more edge-casey than before so
    harder to debug. It occured on my service a few days ago, and left it
    hanging for 28 hours until I restarted it. We also received more reports of
    this on trac. Needs more hardcore debugging + #23671 + #23670.
  - Helped tommy with the upcoming blog post calling for prop224 testing.
  - Revamped the prop224 wiki page some more:
https://trac.torproject.org/projects/tor/wiki/doc/NextGenOnions
