-Priority code is scheduled for removal in Bitcoin Core 0.13. In
-Bitcoin Core 0.12, the default block priority size has been set to `0`

+In Bitcoin Core 0.12, priority transactions are not accepted to the mempool nor
+relayed if mempool limiting has triggered a higher effective minimum relay fee.

+Mining of priority transactions is also now disabled by default. To re-enable
+it, simply set `-blockprioritysize=<n>` where <n> is the size in bytes of your
+blocks to reserve for priority transactions. The old default was 50k, so to
+retain the same policy, you must set `-blockprioritysize=50000`.

+Additionally, calculation of the priority for transactions received with
+unconfirmed inputs is no longer updated correctly when they are received with
+unconfirmed inputs, so miners must continue to use 0.11 if accurate priority
+accounting is important to them.
