This release adds RPC methods for the "Spend before Sync" light wallet feature,
and fixes performance issues and bugs in the mining solution rate RPCs. Progress
bars can now be enabled using a config, please help us test them!

It contains the following updates:

User Testing: Progress Bars

Zebra has progress bars! When progress bars are enabled, you can see Zebra's blocks,
transactions, and peer connections in your terminal. We're asking Zebra users to test this
feature, and give us feedback on the forums.

To show progress bars while running Zebra, add these lines to your zebrad.toml:

[tracing]
progress_bar = "summary"

For more details, including a known issue with time estimates,
read our progress bars blog post.

Security

  • Fix database concurrency bugs that could have led to panics or incorrect history tree data (#7590, #7663)

Added

  • Zebra's progress bars can now be enabled using a zebrad.toml config (#7615)
  • Add missing elasticsearch flag feature to lib docs (#7568)
  • Add missing Docker variables and examples (#7552)
  • Check database format is valid on startup and shutdown (#7566, #7606). We expect to catch almost all database validity errors in CI (#7602, #7627), so users are unlikely to see them on startup or shutdown.

Spend before Sync Support

  • Add state requests and support code for the z_getsubtreesbyindex RPC (#7408, #7734)
  • Implement the z_getsubtreesbyindex RPC (#7436)
  • Test the z_getsubtreesbyindex RPC (#7515, #7521, #7566, #7514, #7628)
  • Format subtree roots in little-endian order (#7466)
  • Add note subtree indexes for new and existing blocks (#7437)
  • Upgrade subtrees from the tip backwards, for compatibility with wallet syncing (#7531)
  • Handle a subtree comparison edge case correctly (#7587)

Changed

  • Return errors instead of panicking in methods for Heights (#7591)
  • Update tests for compatibility with the ECC's lightwalletd fork (#7349)

Fixed

  • Refactor docs for feature flags (#7567)
  • Match zcashd's getblockchaininfo capitalisation for NU5 (#7454)
  • Fix bugs and performance of getnetworksolps & getnetworkhashps RPCs (#7647)
