Mandatory update 0.9.9

Heatledger 0.9.9

This is a mandatory update, all nodes on or below 0.9.8 will be blacklisted.

This release fixes the issue with unconfirmed transactions not being accepted by other peers. Transactions can now be send and received over the network like before.

We've introduced the Upgrader internal component, this helper component allows us to place version specific one time upgrade tasks in new releases. Mostly this will help in you keeping your blockchain and not needing to download it again.

The upgrade function for this release will one time scan and validate your blockchain on startup. It could be you have been running 0.9.8 and are therefor blacklisted by other peers. This blacklisting should take no longer than 10 to 20 minutes.

Forging has not yet been enabled for this release, if all goes well we'll enable forging and rewards again in the coming days.
