0.5.0 - 2026-06-01

💥 Breaking Change

Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

environment:
  sdk: ^3.12.0

🧪 Testing

Improve test coverage to 95%+ across all packages

Added 500+ tests covering equality/hashCode/toString, codec edge cases, error paths, and constructor variants. Removed dead code in fast_stable_stringify. Fixed concurrent modification bug in subscribable.

0.4.0 - 2026-05-30

🚀 Feature

Add Keccak-256 hash function

Adds a pure-Dart Keccak-256 implementation (keccak256()) to solana_kit_codecs_core. This is the hash function used by the Bubblegum compressed NFT program (not to be confused with SHA3-256, which uses different padding).

Note: Keccak-256 round constants exceed 2^53, so ignore_for_file: avoid_js_rounded_ints is applied to the implementation file. This is acceptable because the Solana SDK targets native platforms where int is 64-bit.

📝 Changed

Restructure release groups

Move program-specific and domain-specific packages out of the main release group into standalone release schedules with independent versioning. Core SDK packages remain synchronized in the main group.
