Full Changelog: https://github.com/facebook/akd/compare/v0.8.9...v0.9.0

Version 0.8.9 is released!

There is only 1 major change in this release, which is an opt-out optimization on batch-retrieval of nodes for lookup proof generation. In this case, we can reduce the tree-walk to 2 batch-gets of nodes in order to assist generating lookup proofs faster.

Full Changelog: https://github.com/facebook/akd/compare/v0.8.8...v0.8.9

2. Cleanup of unwrap()s in the codebase #343
3. Use AzksValue as node value instead of Digest #347
