Weave Mesh Release 0.3
This release has a number of changes to defer updates by up to one second, to reduce the cpu usage of route recalculation and reduce network bandwith for topology updates.
The effect is it behaves much better on networks of over 100 nodes.
In small networks you may find things don't update as instantly as before, but it was never wise to depend on that - mesh is explicitly based on gossip and eventual consistency.
