solana_sdk 0.1.1

A pure Dart Solana client library for keys, transactions, programs, and JSON-RPC/WebSocket access.

0.1.1

• Fixed the Vote Program vote instruction ABI and introduced the Vote value type used by VoteProgram.vote.
• Added support for the current durable nonce account layout and preserved the original message bytes when deserializing legacy transactions.
• Fixed stake lockup epoch decoding across the complete Solana u64 range.
• Enforced the v1 message 4096-byte limit and tightened legacy account index, signer, token account, mint, and binary layout validation.
• Preserved u64 RPC values without precision loss. AccountInfo now exposes lamportsBigInt and rentEpochBigInt for the complete range.
• Added automatic WebSocket reconnection and restoration of active subscriptions, including fixes for subscribe/unsubscribe races.
• Tightened JSON-RPC response validation for protocol version, request IDs, batch responses, and malformed payloads.

Compatibility notes

• VoteProgram.vote now accepts a Vote object containing slots, bank hash, and an optional timestamp.
• Lockup.epoch now returns BigInt; its constructor continues to accept either int or BigInt.
• The minimum supported Dart SDK is now 3.2, matching the package's runtime dependencies and documented requirements.

0.1.0

• Added Solana BIP-44 derivation paths and SLIP-0010 Ed25519 key derivation from seed bytes.
• Added RPC helpers for health, snapshot slots, max retransmit/shred insert slots, and token accounts by delegate.
• Added parsed token accounts by delegate and versioned transaction durable nonce detection helpers.
• Added Solana-style message and versioned transaction sanitize() helpers.
• Added structured sanitize exceptions, per-signature verification, verify-and-hash helpers, and durable nonce account lookup.
• Added SIMD-0385 v1 message support, including transaction config fields, versioned transaction wrapping, RPC version parsing, and fee lookup helpers.
• Prepared package metadata for open-source publication.
• Lowered runtime dependency constraints where compatible with the current implementation.
• Added public RPC export coverage tests.
• Kept JSON-RPC request content type stable across supported http versions.
