Notable changes
The mainnet activation of the Heartwood network upgrade is supported by this release, with an activation height of 903000, which should occur in the middle of July — following the targeted EOS halt of our 2.1.2-3 release. Please upgrade to this release, or any subsequent release, in order to follow the Heartwood network upgrade.
The following two ZIPs are being deployed as part of this upgrade:
In order to help the ecosystem prepare for the mainnet activiation, Heartwood has already been activated on the Zcash testnet. Any node version 2.1.2 or higher, including this release, supports the Heartwood activation on testnet.
Mining to Sapling addresses
After the mainnet activation of Heartwood, miners can mine directly into a
Sapling shielded address. Miners should wait until after Heartwood activation
before they make changes to their configuration to leverage this new feature.
After activation of Heartwood, miners can add mineraddress=SAPLING_ADDRESS to
their zcash.conf file, where SAPLING_ADDRESS represents a Sapling address
that can be generated locally with the z_getnewaddress RPC command. Restart
your node, and block templates produced by the getblocktemplate RPC command
will now have coinbase transactions that mine directly into this shielded
address.
Changelog
Aaron Clauson (1): Minimal code changes to allow msvc compilation.
Adam Langley (1): Switch memory_cleanse implementation to BoringSSL's to ensure memory clearing even with link-time optimization.
Alfredo Garcia (12): fix rpc testcase add blockheight, blockindex and blocktime to z_listreceivedbyaddress change time to blocktime in help add status to transactions minor fix minor cleanup style, var names Add a new safe chars rule for node version string fix wallet nullifiers test Fix typo add a test case implement z_getnotescount api call remove not needed help parameters to dump and import impl

Daira Hopwood (2): Fix a null pointer dereference that occurs when formatting an error message, if we haven't activated an upgrade as expected. Explicitly assert that chainActive[upgrade.nActivationHeight] is non-null at this point.
Dimitris Apostolou (1): Fix typos
Jack Grigg (5): Use BOOST_SCOPE_EXIT_TPL to clean and free datValue in CDB::Read Improve memory_cleanse documentation Add NU4 to upgrade list Add NU4 test helpers Update URLs for prior network upgrades
Jonathan "Duke" Leto (1): Add confirmations to z_listreceivedbyaddress

Add a test reproducing the off-by-one error.
Check network reunification.
Narrow down the test case.
Make the test reproduce the actual off-by-one error in rewind length.

Sean Bowe (11): Add NU4 activation to golden test. Update minimum chain work on testnet to reflect Heartwood activation. Pass DO_NOT_UPDATE_CONFIG_SCRIPTS=1 to autogen.sh in libsodium dependency, to avoid updating config scripts over the network. Set the Heartwood activation height to 903000.
