Merge branch 'tor-gitlab/mr/254' into maint-0.3.5

parents 045db909 04b02639
Pipeline #2383 failed with stage
in 18 minutes and 2 seconds
o Major bugfixes (onion service v3):
- Stop requiring a live consensus for v3 clients and services to work. The
use of a reasonably live consensus will allow v3 to work properly in most
cases if the network failed to generate a consensus for more than 2 hours
in a row. Fixes bug 40237; bugfix on 0.3.5.1-alpha.
