Fixed

Breaking Changes

• The Horizon API Transaction resource field in json result_meta_xdr is now optional and Horizon API will not emit the field when Horizon has been configured with SKIP_TXMETA=true, effectively null, otherwise if Horizon is configured with SKIP_TXMETA=false which is default, then the API Transaction field result_meta_xdr will remain present and populated with base64 encoded xdr (5228).
