Release v15.0.0 · stellar/js-stellar-base

`v15.0.0`: Protocol 26

TransactionBase.networkPassphrase setter now throws an error to enforce immutability (#891).
React Native apps using the Hermes engine must polyfill broken typed array methods such as subarray; this compatibility is no longer provided by @stellar/js-xdr. One option is @exodus/patch-broken-hermes-typed-arrays. If needed, please review and consider manually adding it to your project.
Construction and encoding of sized XDR integer values now throw on overflow and underflow instead of silently clamping, via @stellar/js-xdr (#133). This may affect code that previously relied on permissive bigint coercion.

Keypair.verify now returns false instead of throwing when the signature is invalid (#892).
Memo.id now correctly rejects negative values, decimal values, and values exceeding the uint64 maximum (2^64 - 1); the error message now correctly says uint64 (#892).
Operation._toXDRPrice now accepts price objects with n: 0 (a zero numerator was previously treated as falsy and fell through to float approximation) (#892).
SignerKey.decodeSignerKey now reads the exact payload length from the 4-byte length prefix when decoding signedPayload signer keys, preventing data truncation or over-read (#892).
TransactionBuilder.cloneFrom now correctly re-encodes extraSigners as StrKey strings (they were previously passed as raw XDR objects) (#892).
TransactionBuilder.cloneFrom now uses Math.floor when computing unscaledFee to prevent fractional fee values (#892).
TransactionBuilder now floors Date timebounds to integer UNIX timestamps (#892).
Auth.bytesToInt64 now correctly handles bytes with upper-32-bit values set by processing each 32-bit half independently (#891).
ScInt constructor now correctly handles string input (#891).
Soroban.parseTokenAmount now throws when the input value has more decimal places than the specified decimals argument (#891).
XDR Array and VarArray decoding now fails fast when the declared array length exceeds the remaining bytes, via @stellar/js-xdr (#132).
