In the next major release of the LSST stack, the system for measuring the properties of sources will be replaced by a new one, housed mostly in the new meas_base package. In addition to providing new Task classes and a new plugin interface for measurement algorithms, this overhaul also includes changes to the schemas of the catalogs produced by the measurement framework. The new framework will not be entirely complete as of the next releto a schema, you follow the naming conventions for the schema version of the framework you are using.aserelease, but it will have sufficient functionality to replace the old framework as the default. The old system will remain available via config on the S14 final release, but will be removed entirely before the W15 release.
