- o Major bugfixes (congestion control):
- - Implement RFC3742 Limited Slow Start. Congestion control was
- overshooting the congestion window during slow start, particularly for
- onion service activity. With this fix, we now update the congestion
- window more often during slow start, as well as dampen the exponential
- growth when the congestion window grows above a capping parameter.
- This should reduce the memory increases guard relays were seeing, as
- well as allow us to set lower queue limits to defend against
- ongoing DoS attacks. Fixes bug 40642; bugfix on 0.4.7.5-alpha.
