1 Apr 2020


      Hello,
Last week I messed up my pre-meeting schedule and didn't get around to
send out the notes from the meeting the week before. Both of them are
gathered in this email with summaries in the top and the pads in the
bottom.

2) Not much progress on 0.4.3 status. We might delay this release a
little bit.
3) People were asked to cast votes on different policy docs.
4) We did some rotation of s28/s30 tickets in the team.
5) Nobody else had anything to add.
Meeting notes 23/3 2020:
Logs at http://meetbot.debian.net/tor-meeting/2020/tor-meeting.2020-03-23-16.59.html
1) We went over roadmap. We were talking about how the board isn't kept
well in sync with reality and Trac.
2) Reviews looked fine for this week.
3) We went over 0.4.3 status.
4) We shortly discussed CI problems on macOS. We are waiting a response
from the Travis people.
5) Should we defer 0.4.3 status to early April? Nobody had any
objections.
6) We need more people helping out with volunteers on IRC. There are
many people coming in right now asking Tor dev questions. Please help
them out if you see nobody else is :-)
7) We shortly talked about alternative support forums than IRC.
8) Nobody had anything else to add.
