v0.8.7
Another release with minor but steady network improvements which should lead
to a more stable blockchain network, and some technical debt reductions.
This should lead to improvements on the overall connections management, so that
an oversubscribed node has always room to open a new connection for its own
benefits and that idle connections are recycled more aggresively. Some
improvements on the locking will also reduce performance problems.
We also have some dependencies updates, and some parts has been rewritten to
the now rust standard async and futures, leading to sustantially simpler
and cleaner code in many places. This is just the start of this work.
