build(deps): bump @solana/instruction-plans from 7.0.0 to 8.1.0

[dependabot]

Bumps @solana/instruction-plans from 7.0.0 to 8.1.0.

Release notes

Sourced from @​solana/instruction-plans's releases.

v8.1.0

@​solana/kit

v8.1.0 (2026-08-27)

Minor Changes

• [@solana/errors, @solana/transaction-messages] #1972 7d56e29 Thanks @​skyyycodes! - Validate compute unit limit and heap size when they are set on a transaction message

  setTransactionMessageComputeUnitLimit, setTransactionMessageHeapSize and setTransactionMessageConfig now reject values the runtime will not honor as written, throwing SOLANA_ERROR__TRANSACTION__COMPUTE_UNIT_LIMIT_OUT_OF_RANGE or SOLANA_ERROR__TRANSACTION__INVALID_HEAP_SIZE at the point the value is set. An invalid heap size fails the transaction on-chain; a compute unit limit above the maximum is instead clamped down by the runtime, so the transaction quietly runs with a budget other than the one requested. A compute unit limit must be an integer in the range [0, 1,400,000]; a heap size must be an integer multiple of 1 KiB between 32 KiB and 256 KiB inclusive.

  Decoding is unaffected: decompileTransactionMessage still returns messages carrying out-of-range values so that callers can inspect any transaction that reaches them.

• [@solana/instruction-plans] #1995 95a2788 Thanks @​mcintyre94! - Add createTransactionPlanExecutorWithConcurrentLeaves to concurrently transform every transaction plan leaf while preserving the plan's result shape.

Patch Changes

• [@solana/codecs-core] #1970 be30e32 Thanks @​koriyoshi2041! - Fix toArrayBuffer slicing SharedArrayBuffer-backed views from a non-zero byte offset.

• [@solana/codecs-data-structures] #1971 c51b9f6 Thanks @​shin4141! - Preserve the literal fixedSize type for single-field fixed-size struct codecs.

• [@solana/codecs-strings] #1979 6852054 Thanks @​amilz! - Fixed getBase64Decoder() throwing RangeError: Maximum call stack size exceeded in browser builds when decoding byte arrays larger than roughly 65KB. The bytes are now converted to a binary string in chunks rather than spread into a single String.fromCharCode call.

• [@solana/rpc, @solana/transaction-confirmation] #1994 490ac9e Thanks @​matusbalascak! - Fix transaction confirmation and coalesced RPC request cancellation in environments where abort events have a null target.

Major Changes

• [@solana/instruction-plans] #1913 80368eb Thanks @​mcintyre94! - Stop writing to the execution context in createTransactionPlanExecutor

  The executeTransactionMessage callback can no longer return a Signature or a Transaction. Those return values were deprecated when the callback gained the ability to return the context that a successful result should carry, and they are now gone: that context, a complete TContext, is the only thing the callback returns. Nothing is written to it on your behalf.

  const transactionPlanExecutor = createTransactionPlanExecutor({
    executeTransactionMessage: async (context, message) => {
      const transaction = await signTransactionMessageWithSigners(message);
      context.transaction = transaction;
  +   const signature = getSignatureFromTransaction(transaction);
      await sendAndConfirmTransaction(transaction, { commitment: 'confirmed' });
  -   return transaction;
  +   return { signature, transaction };
    },
  });

  The mutable context argument is still there, and still serves the failure path: whatever the callback stores on it before it throws is preserved in the resulting FailedSingleTransactionPlanResult. The two channels differ only in which outcome they feed. Mutating the context makes a value available to a failed result; returning it makes a value available to a successful one. On success the two are merged, with the returned value taking precedence, so a property stored but not returned is still reported.
