+ o Minor bugfixes (path selection):
+ - When selecting relays by bandwidth, avoid a rounding error that
+ could sometimes cause load to be imbalanced incorrectly. Previously,
+ we would always round upwards; now, we round towards the nearest
+ integer. This had the biggest effect when a relay's weight adjustments
+ should have given it weight 0, but it got weight 1 instead.
+ Fixes bug 23318; bugfix on 0.2.4.3-alpha.
