  o Minor features (protocol simplification):
    - Tor no longer allows subprotocol versions larger than 63.  Previously
      versions up to UINT32_MAX were allowed, which significantly complicated
      our code.
      Implements proposal 318; closes ticket 40133.
Implement proposal 318: Limit protovers to 0..63 In brief: we go through a lot of gymnastics to handle huge protover numbers, but after years of development we're not even close to 10 for any of our current versions. We also have a convenient workaround available in case we ever run out of protocols: if (for example) we someday need Link=64, we can just add Link2=0 or something. This patch is a minimal patch to change tor's behavior; it doesn't take advantage of the new restrictions. Implements #40133 and proposal 318. 2020-10-14 17:28:37 +02:00			`o Minor features (protocol simplification):`
