v6.5.0 (2026-03-19)

[@solana/plugin-interfaces] #1486 10cb920 Thanks @lorisleiva! - Add ClientWithGetMinimumBalance plugin interface for computing the minimum balance required for an account. Implementations can use any strategy (e.g., RPC call, cached value) to provide this value through a uniform API.
[@solana/signers] #1487 9e05736 Thanks @lorisleiva! - Add partiallySignTransactionWithSigners, signTransactionWithSigners, and signAndSendTransactionWithSigners functions that accept a set of signers and a compiled Transaction directly, without requiring signers to be embedded in a transaction message. Also add assertContainsResolvableTransactionSendingSigner to validate that a set of signers contains an unambiguously resolvable sending signer. The existing transaction message helpers now delegate to these new functions internally.

[@solana/kit] #1485 4a4c217 Thanks @lorisleiva! - Deprecated getMinimumBalanceForRentExemption. The minimum balance for an account is being actively reduced (see SIMD-0437) and is expected to become dynamic in future Solana upgrades (see SIMD-0194 and SIMD-0389). Use the getMinimumBalanceForRentExemption RPC method or a ClientWithGetMinimumBalance plugin instead. This function will be removed in v7.
