This will be moved to Gitlab ASAP
S28 & S30 - Continue after October - Ahf
S55 - Nickm & dgoulet
Non sponsor stuff
DoS defenses = Dgoulet + Asn
Library Size reduction = Ahf + Dgoulet
sbws = Ahf + Juga
Check reviewer assignments! How reviews from last week worked? Any
blocker? Here are the outstanding reviews, oldest first, including sbws:

Go over our 0.4.4 status page at
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases/044Status
. (If maint-0.4.4 were released as stable tomorrow, what would we
regret?) - scheduled to enter feature freeze on Monday June 15th
== Reminders ==
* Remember to "/me status: foo" at least once daily.
* Remember that our current code reviews should be done by end-of-week.
* Make sure you are in touch with everybody with whom you are doing work
for the next releases.
* Check other's people call for help in their entries.
Volunteers need help. Please help them when you are around. Maybe we
should have times of day when different people are responders, and
expectations of who helps.
