[tor-commits] [stem/master] BandwidthFile tor_version attribute
commit 8b09cbd778ccd2c4a350f00f0a1836a55b75ef4c
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>

BandwidthFile tor_version attribute
Adding our bandwidth file's tor_version. The spec claims that it's a version
1.5.0 attribute...
https://gitweb.torproject.org/torspec.git/commit/?id=7d8b4bc
However, our most recent bandwidth files have this attribute yet claim to be
1.4.0. Maybe our scanners added the attribute without bumping their version?
Working under that assumption and reached out to juga.
