* BIP65/block version 4 compatibility
* Requires Bitcoin >=0.11.2 (for BIP65 compatibility)

BIP65 will take effect in the next week 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 BIP65 takes effect, P2Pool users will be
subject to paying other users for invalid work - effectively a
withholding attack.

So, please upgrade to 15.0 now and tell everyone else to also.

This is a reminder to please upgrade your P2Pool instances. We are
behind where we should be, relative to the possible Bitcoin network
switchover date [1].
