The v0.24.0 release introduces key functional improvements, including full verification support for HAPI 0.68.x through a hashing refactor, and the addition of greedy autonomous backfill, which enhances historical block recovery and fixes edge cases in empty stores. Block parsing is strengthened with updated Unparsed Proto support for the Block Footer, improving correctness across the pipeline.
This version also upgrades the PBJ compiler to 0.12.10, bringing better proto generation and runtime stability. Supporting updates include new k6 smoke tests, improved socket-closure e2e coverage, hardened BlockAccessor behavior, optimized Helidon 4.3.2 configs, and a series of dependency bumps for ecosystem alignment and reliability.
