-Zcash Core 0.11.2.z7
+Zcash Core 0.11.2.z8
 ====================
 
 [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.

+Daira Hopwood (1):
+      README.md: simplify the title, drop "Core"
+
+Jack Grigg (23):
+      Make Equihash solvers cancellable
+      Add tests that exercise the cancellation code branches
+      Fix segfault by indirectly monitoring chainActive.Tip(), locking on mutex
+      Move initialisations to simplify cancelled checks
+      Use std::shared_ptr to deallocate partialSolns automatically
+      Equihash: Pass each obtained solution to a callback for immediate checking
+      Remove hardfork from special testnet difficulty rules
+      Fix bug in 'generate' RPC method that caused it to fail with high probability
+      Add thread parameter to solveequihash benchmark
+      Eliminate some of the duplicates caused by truncating indices
+      Use fixed-size array in IsProbablyDuplicate to avoid stack protector warning
+      Eliminate probably duplicates in final round
+      Simplify IsProbablyDuplicate()
+      Add missing assert
+      Simplify optional parameters
+      Fix previous commit
+      Remove the assumption that n/(k+1) is a multiple of 8.
+      Add Equihash support for n = 200, k = 9
+      Add test showing bug in IsProbablyDuplicate()
+      Fix bug in IsProbablyDuplicate()
+      Change Equihash parameters to n = 200, k = 9 (about 563-700 MiB)
+      Update tests to account for new Equihash parameters
+      Ignore duplicate entries after partial recreation
+
+Simon (21):
+      Inform user that zcraw... rpc calls are being deprecated.
+      Add GetTxid() which returns a non-malleable txid.
+      Update genesis blocks.
+      Update precomputed equihash solutions used in test.
+      Update block and tx data used in bloom filter tests.
+      Updated test data for script_tests by uncommenting UPDATE_JSON_TESTS flag.
+      Rename GetHash() method to GetSerializeHash().
+      Replace calls to GetHash() with GetTxid() for transaction objects.
+      Set nLockTime in CreateNewBlock() so coinbase txs do not have the same txid. Update test data in miner_tests.
+      Refactor GetTxid() into UpdateTxid() to match coding style of hash member variable.
+      Revert "Set nLockTime in CreateNewBlock() so coinbase txs do not have the same txid."
+      Fix issue where a coinbase tx should have it's sigscript hashed to avoid duplicate txids, as discussed in BIP34 and BIP30.
+      Update genesis block hashes and test data.
+      Make txid const.
+      Update deprecation message for zcraw api.
+      Fix comment.
+      Update comment.
+      Extend try catch block around calls to libsnark, per discussion in #1126.
+      Remove GetSerializeHash() method.
+      Use -O1 opimitization flag when building libzcash. Continuation of #1064 and related to #1168.
+      Add test for non-malleable txids.  To run just this test: ./zcash-gtest --gtest_filter="txid_tests*"
+
+Taylor Hornby (8):
+      Make the --enable-hardening flag explicit.
+      Enable -O1 for better FORTIFY_SOURCE protections.
+      Add checksec.sh from http://www.trapkit.de/tools/checksec.html
+      Add tests for security hardening features
+      Pull in upstream's make check-security, based on upstream PR #6854 and #7424.
+      Make security options in configure.ac fail if unavailable.
+      Put hardened stuff in libzcash CPPFLAGS.
+      Add more commands to run unit tests under valgrind.
