Update your Zcash client to 2.0.0 or above. Nodes which haven’t updated will exit with an error message requesting an update prior to the upgrade. The only way you will miss the upgrade is if you are running your own full node and manually configured your client to continue running the legacy software.
Users upgrading from earlier 1.x releases will need to download the additional Sapling parameters which are just under 800MB in size.
For support of Sapling in the RPC interface, you will need version 2.0.1 or above.
Zcash is cash
for a new era.
