ZcashFoundation/zebra v4.0.0

Zebra 4.0.0

on GitHub

This release fixes the type of a field in the getinfo RPC and adds support for
the pingtime and pingwait fields of the getpeerinfo RPC.

It also changes the Grafana dashboards to add auto-provisioning and AlertManager
support.

This release also adds a new mainnet DNS seeder from Shielded Labs to the default
configuration. However, if you already have a config in place, you will need
to add it manually; add "mainnet.seeder.shieldedinfra.net:8233" to
initial_mainnet_peers.

The new OpenTelemetry support must be enabled at compile time with the
opentelemetry feature, e.g. cargo build --features=opentelemetry --release.

Breaking Changes

This release has the following breaking changes:

• Changed the getinfo RPC errorstimestamp field from a string timestamp (ISO
  UTC timestamp) to a i64 (seconds from Unix epoch) to match zcashd
  (#10079). If you rely
  on this field, you will need to change your code to be able to interpret
  the i64 result.
• Always parse Zebra's config file as TOML (#10222). This allows using a config
  file with an extension different than .toml. Previously, it would use the
  format detected from the extension, so in the unlikely case you were using
  a format different than TOML you will need to change your config to TOML.
