Issue #12990: rapidjson has been removed from canvas--it is used only in art and already exists there.
Issue #13272: Spurious output files are no longer produced in the artdaq context whenever RootOutput file-switching is configuration (also resolves issue #13174).
Issue #13464: A segmentation violation encountered when initializing messagefacility in single-threaded mode has been fixed.
A new required link-time dependency on ROOT_CORE was discovered for services. Although this dependency was introduced in art2.01.00, it was first noticed here. This issue has been resolved in art2.03.00.
