Notable changes Notable changes
=============== ===============
The mainnet activation of the Canopy network upgrade is supported by this
release, with an activation height of 1046400, which should occur roughly in the
middle of November — following the targeted EOS halt of our 3.1.0 release.
Please upgrade to this release, or any subsequent release, in order to follow
the Canopy network upgrade.
The following ZIPs are being deployed as part of this upgrade:
* [ZIP 207: Funding Streams](https://zips.z.cash/zip-0207) in conjunction with [ZIP 214: Consensus rules for a Zcash Development Fund](https://zips.z.cash/zip-0214)
* [ZIP 211: Disabling Addition of New Value to the Sprout Value Pool](https://zips.z.cash/zip-0211)
* [ZIP 212: Allow Recipient to Derive Sapling Ephemeral Secret from Note Plaintext](https://zips.z.cash/zip-0212)
* [ZIP 215: Explicitly Defining and Modifying Ed25519 Validation Rules](https://zips.z.cash/zip-0215)
In order to help the ecosystem prepare for the mainnet activiation, Canopy has
already been activated on the Zcash testnet. Any node version 3.1.0 or higher,
including this release, supports the Canopy activation on testnet.
Disabling new value in the Sprout value pool
--------------------------------------------
After the mainnet activation of Canopy, it will not be possible to send funds to
Sprout z-addresses from any _other_ kind of address, as described in [ZIP 211](https://zips.z.cash/zip-0211).
It will still be possible to send funds _from_ a Sprout z-address and to send
funds between Sprout addresses. Users of Sprout z-addresses are encouraged to
use Sapling z-addresses instead, and to migrate their remaining Sprout funds
into a Sapling z-address using the migration utility in zcashd: set `migrate=1`
in your `zcash.conf` file, or use the `z_setmigration` RPC.
