Update the SDK to the stable Protocol 20 release

CHANGELOG.md

@@ -7,6 +7,11 @@ As this project is pre 1.0, breaking changes may happen for minor version bumps.
 * Update `LedgerResponse` and `AccountResponse`, remove outdated fields, and add missing fields. ([#549](https://github.com/stellar/java-stellar-sdk/pull/549))
 * Add support for muxed accounts in `PaymentOperationResponse`. ([#550](https://github.com/stellar/java-stellar-sdk/pull/550))
 * Use `Price` instead of `String` to represent prices. Change the type of `CreatePassiveSellOfferOperation.price`, `ManageBuyOfferOperation.price`, and `ManageBuyOfferOperation.price` from `String` to `Price`, this fixes the issue of incorrect operations parsed in certain specific scenarios. ([#554](https://github.com/stellar/java-stellar-sdk/pull/554))
+* Update the SDK to the stable Protocol 20 release: [#553](https://github.com/stellar/java-stellar-sdk/pull/553)
+  - The `BumpFootprintExpirationOperation` is now `ExtendFootprintTTLOperation` and its `ledgersToExpire` field is now named `extendTo`, but it serves the same purpose.
+  - The `InvokeHostFunctionOperation.createTokenContractOperationBuilder` is now `InvokeHostFunctionOperation.createStellarAssetContractOperationBuilder`.
+  - `SorobanDataBuilder.setRefundableFee` is now `setResourceFee`.
+  - The RPC endpoint structure has changed, check [#552](https://github.com/stellar/java-stellar-sdk/issues/552) for more details.
 
 ## 0.41.1
 * Add `org.stellar.sdk.spi.SdkProvider`, users can implement this interface to provide their own implementation of the SDK. We provide an [Android specific implementation](https://github.com/stellar/java-stellar-sdk-android-spi), if you are integrating this SDK into an Android project, be sure to check it out.
