Network team will be releasing on Friday a new alpha (0.4.7.4-alpha) but this
one is very special, it is the first alpha with the gigantic congestion
control work in it.
There are also couple important fixes for relay operators running alphas and
so we will recommend to upgrade.
With this alpha, we hope to get to a release candidate very soon and then onto
the long awaited 0.4.7 stable in around 2-3 months.
@network-team: It is _now_ a good time to start reviewing changes/ files:
Last, we've asked the dirauth to recommend these versions few minutes ago.
