v8.2.0 (2026-08-29)

[@solana/instruction-plans] #2013 26edd3b Thanks @mcintyre94! - Align createTransactionPlanExecutorWithConcurrentLeaves with createTransactionPlanExecutor by giving both the same TransactionPlanExecutorConfig. Its executeTransactionMessage callback now receives a mutable per-leaf context object and returns the context of a successful result, instead of building a whole SingleTransactionPlanResult itself. The executor builds the results: on success it merges the returned context over the stored one, and when the callback throws — or the abort signal fires before it settles — it preserves the stored context on the failed result, matching the partial-context behaviour of createTransactionPlanExecutor. The ConcurrentLeafTransactionPlanExecutorConfig type is removed. This is a breaking change to the createTransactionPlanExecutorWithConcurrentLeaves API introduced in 8.1.0.

[@solana/signers] #2006 d385ce3 Thanks @amilz! - Relaxed the parameter type of the signer type guards (isMessagePartialSigner, isTransactionSigner, isKeyPairSigner, their siblings, and the assertIs* variants) so that class instances implementing a signer interface can be passed without casts. The guards now accept any TValue extends { address: Address } and narrow to TValue & Signer, whereas the previous parameter type required an implicit index signature, which TypeScript never grants to class instances.
