The Zcash Foundation is pleased to announce the release of Zebra version 1.5.2.
This latest version is a hotfix release, to temporarily remove the experimental internal-miner feature introduced in the preceding 1.5.1 release. Following the 1.5.1 release on GitHub, we identified difficulties in publishing the zebra-chain crate to crates.io.
Unfortunately, to resolve this challenge, which involves an unpublished dependency, we had to temporarily remove the internal miner support introduced in version 1.5.1.
The 1.5.1 release includes a utility for reading results from the zebra blockchain scanner, thus finalizing a minimum viable product for scanning the Zcash blockchain with a viewing key. It also added an experimental internal-miner feature, temporarily removed with the 1.5.2 hotfix release, which can mine blocks within zebrad. This feature is only supported on testnet as you need to use a more efficient GPU or ASIC for mainnet mining.
We plan to reinstate the internal-miner feature once our PRs are merged and released into the equihash dependency. You can track development progress on this issue here.
As part of this release we have also improved our documentation with details on how to use the new blockchain scanning feature as well as making it easier to find documentation for all our crates in docs.rs.
