* Remember: don't spend more than a day working on anything that isn't on
the 033 or 034 milestones.

== Discussion ==
* Should 0.3.4 be a long-term support release? How do we pick our next
- Can we just tell Debian to use it as a LTS? What about other
platforms? - teor
* Are we ready to release 0.3.3? -NM
- [dgoulet] We should get the TROVE finalized. Apart from that, I think
- [ahf] I still have #25245 open, I do have a patch to do some
diagnostics, but it's very annoying to reproduce locally. It's marked
priority = very high, but I don't know if we think it's a blocker?
== Updates ==
[Migh be off for May 1st excursion at the time of the meeting.]
- Reviewed and helped with #25870. This is complex stuff! To better
the ticket, I wrote some initial unittests for path selection for normal
exit circuits and vanguards. They are still quite simple but they can be
basis of something good.
- Pushed bugfixes and features to the vanguard simulator (#23978) based on
- Reviewed #23693.
- Provided feedback to the 2-guard proposal thread.
- Gave a bit of testing to haxxpop's v3 client auth branch. Seems to work!
also motivated some more people to try it out and find bugs. Next step
find time for code review. We are hoping for 035 inclusion.
- Discussed v3 intro auth with haxxpop.
- Wrote patch for #25843 and got it merged.
- Replied to "[tor-dev] onion v2 deprecation plan?" thread.
- Suggested some tasks to our ahmia SoP student.
- Continue discussion on the 2-guard proposal thread. We are doing good
- Discuss with Mike what's needed next for the vanguard simulator.
- Triage tickets out of 034 with my name that I don't have time for. Most
them were the result of 033 -> 034 triaging.
- Hopefully find some time for #25552.
- Reviewed #24734, wrote a couple fixups forit.
- Worked on #25870 (vanguard path restrictions) with asn.
- Proposal 291 mailinglist posts (enumerated 8 properties defenses have
and developed one that got all of them)
- Refined #25903 (CIRC_BW events that help check for dropped-cell side
channels); updated vanguard repo to use them; tested them.
- Reviewed #25843 (NumEntryGuards param). asn - are you sure that it is
influencing our dirguards? it looks like no.
last week (2018-W17):
- investigated some unexplained test coverage fluctuations revealed
- opened #25908 to stabilize test coverage. thanks nickm for doing
some inital data gathering!
- more call stack analysis for #25061
- deferred #25061 to 034

location when doing a distcheck build in travis)
