Spring v2.0.0-dev1.1 changes the behavior of get_sender() in sync calls based on developer feedback. See #1738 for details. For compatibility with the live developer preview testnet this modification is being done as a temporary protocol feature for the dev1 release. Future releases will include this new behavior in the SYNC_CALL protocol feature.
Nodes connected to the developer preview testnet will need to upgrade to this release. Nodes on private or local testnets should activate GET_SENDER_FIX to get the updated behavior.
Warning
This is a Developer Preview release, intended for testing and feedback only. Future releases will contain breaking changes. Data files created by 2.0.0-dev1.1 (such as block logs, snapshots, state history logs, etc) will not necessarily be compatible with any future releases. 2.0.0-dev1.1 should not be used on chains other than chains specifically testing the 2.0.0-dev1.1 preview release.
