Merged requested to merge er433/deprecation/constants into dev
For LIGO developers
We have had deprecated constants for a long time, but we started emitting warning messages about deprecation 45 days ago (Mar 15 2022, !1623 (merged)).
This MR finally removes deprecated constants.
In previous versions of LIGO, warnings were emitted for deprecated constants (e.g.
sender, etc.). We finally remove those constants. Please consult API documentation in ligolang.org to find a new constant that can replace the old one in your contract.
