 ## Pending
 - feat: sort `ScMap` entries by key in `Scv.toMap` following Soroban runtime ordering rules, as the network requires ScMap keys to be in ascending order. `Scv.toMap` now accepts `Map<SCVal, SCVal>`; the previous `toMap(LinkedHashMap<SCVal, SCVal>)` overload is deprecated.
 - feat: add `closeTime`, `headerXdr`, and `metadataXdr` to `GetLatestLedgerResponse`.
+- chore: bump [stellar-xdr](https://github.com/stellar/stellar-xdr) to v25.0.
