* HMAC now calculated correctly - confirmed interop with Google's public hub * Can optionally use an external PuSH hub, set URL in $config['ostatus']['hub'] (may have issues in replication environment, and will ping the hub for every update rather than just those with subscribers) Internal hub will still function when this is set, but won't be advertised. Warning: setting this, then turning it off later will break subscriptions as that hub will no longer receive pings.
