Zcash (ZEC) v6.2.0 Revision
The Zcash crew has officially commenced the deprecation process of zcashd in 2025. All complete nodes are being shifted to zebrad, and a new wallet known as Zallet is in the works as a substitute for the zcashd wallet interface.
While numerous JSON-RPC methods will be supported in zebrad or Zallet as drop-in substitutes, others may necessitate alterations, and some will be entirely unavailable. If you utilize zcashd for mining or various integrations, please check the JSON-RPC compatibility spreadsheet and submit your insights to facilitate improved migration support.
Platform Note: Support for Ubuntu 20.04 LTS has been withdrawn. It will reach its end of support in May 2025 and no longer satisfies Tier 2 policy requirements due to GitHub runner limitations.
