What has changed

New Features

• Expose raw binary account contents from GraphQL Sai/snark ledger query serialized #16000
• Expose ledger membership proofs from GraphQL for ultra-lite clients / wallets Sai/query snarked ledger compatible #15987
• GraphQL command to request 'protocol state' for a particular block Add support for querying protocol state by state hash or height #15893
• Reduce duplicated snark work across the network with 'random offset' mode Work_selector: add random offset selection #15981

To use this option, add --work-selection roffset to the snark worker daemon command.
In the new option, the worker computes a random number, and fetch work sequentially starting from this index in the list of required work. This methods is expected to reduce wasted work and preserving throughput compared to random, but does not guarantee the priority of work production. The optimal approach for someone running several workers is to run a few worker with the sequential method, to ensure the priority work is ready, and the rest of the worker with the random offset selection to reduce wasted work and improve throughput.

Bug Fixes

• Fix epochDelegateAccount GraphQL command Fix epochDelegateAccount GraphQL command to match its description #15949

Improvements

• Speed up processing of slow transactions by ~20% Handle non-existent accounts in preload #15978 / Do not recompute hashes on ledger commit #15979
• Security upgrade to arkworks 0.4.2 Update arkworks to 0.4.2 (compatible) #15940
• Rosetta available as its own debian package Introduce separate rosetta debian #15897
• Full support of the nix build system Granular nix #15848

Complete Changelog since 3.0.1:

3.0.1...3.0.2

Supported environments include macOS, Linux (Debian 11 and Ubuntu 20.04 LTS), and any host machine with Docker.

Debian 10 is no longer a supported operating system and as such is not tested as part of our release process. We recommend that users upgrade to a more recent supported operating system.
