Hi folks,
I just released 0.2.4.17-rc. Hopefully there will be debs of it soon.
It comes with a new feature: - Relays now process the new "NTor" circuit-level handshake requests with higher priority than the old "TAP" circuit-level handshake requests. We still process some TAP requests to not totally starve 0.2.3 clients when NTor becomes popular. A new consensus parameter "NumNTorsPerTAP" lets us tune the balance later if we need to. Implements ticket 9574.
So the more relays that upgrade to 0.2.4.17-rc, the more stable and fast Tor will be for 0.2.4 users, despite the huge circuit overload that the network is seeing.
Can we have a torrc option to make a relay NTor-only?
Could help on some CPU-limited relays like the Raspberry Pi or (in my case) Intel Atom.
With some mechanism to ensure that TAP-only clients do not even see or try to use that relay (so they don't experience any broken connections).
