 > Using
 [https://trac.torproject.org/projects/tor/attachment/ticket/32672/old_bridges.py
 this tool] and a bridge-descriptor file from 13 Mar 2020 07:18:51 PM UTC,
 I looked for bridges that run 0.4.0.* or 0.2.9.*. These are the ones we
 should contact, correct?

 This patch also rejects unstable 0.3.5 versions, that is, 0.3.5.6-rc and
 earlier.

 There aren't any relays on those versions, so there might not be any
 bridges, either.

 > The data shows that 96 out of 1,673 (5.7%) bridges run old Tor version.
 Among these 96, only 52 (54.2%) have (mostly) valid contact information.

 Great, let's try to contact them before we merge the patch.
