Changes:
* CSV compatibility
* Requires Bitcoin >=0.12.1

Several BIPs will take effect in the next few days and in order for
P2Pool to continue working without producing invalid blocks, everyone
needs to upgrade. At 50% of our hashrate upgrading, P2Pool instances
will start displaying a warning saying that an upgrade is required.
Reaching that point as quickly as possible is very important. And
then, at 95%, users that have not upgraded will be excluded. If
non-upgraded users aren't excluded before the Bitcoin changes takes
effect, P2Pool users will be subject to paying other users for invalid
work - effectively a withholding attack.

So, please upgrade to 16.0 now and also tell everyone else to.
