+Zcash Core 0.11.2.z7
 ====================
 
 [Zcash](https://z.cash/) is the Zcash client. It downloads and stores the entire history of Zcash transactions (which is currently several GBs); depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.

+      Update libsnark to our fork.
+      Initialize libsodium in this routine, which is now necessary because libsnark uses its PRNG.

+      Rename `pour` in RPC tests.
+      Remove the constraint system from the alpha proving key.
+      Introduce `zcsamplejoinsplit` for creating a raw joinsplit description, and use it to construct the joinsplit for the performance tests that verify joinsplits.
+      Bump the (minimum) protocol version to avoid invoking legacy behavior from upstream.
+      Remove more from libsnark, and fix potential remote-DoS.
+      Add test for non-intuitive merkle tree gadget witnessing behavior.

+bitcartel (15):
