- loopback no longer exports "caller" and "arguments" properties
- kv-memory connector is now properly added to the connector registry
- the file "test/support.js" was finally removed
- Removes backward compatibility
for legacy end points `/models` & `/routes`
- Removes `legacyExplorer` flag which
enabled these routes
- Update related tests & tests using the
legacyExplorer flag
