In July, Tor 0.3.0 became the most common relay version in the network,
growing at quite a rapid rate:

https://metrics.torproject.org/versions.html

There doesn't seem to be any corresponding Tor Browser release in that
timeframe:

3 July: https://blog.torproject.org/blog/tor-browser-702-released
8 August: https://blog.torproject.org/blog/tor-browser-704-released

(Our estimates suggest that half the load on directory authorities is
from relays, and half is from clients.)

I wonder if the new guard selection algorithm, or some other relay
change, is causing relays to download more descriptors from more
directory authorities?
