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:
|
||
|
|
||
|
- [ZIP 213: Shielded Coinbase](https://zips.z.cash/zip-0213)
|
||
|
- [ZIP 221: FlyClient - Consensus-Layer Changes](https://zips.z.cash/zip-0221)
|
||
|
|
||
|
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.
|
||
