Debugging: Logging Improvements, More Debugging for ISVs, Event Types for External Object Callouts
Public site users no longer need a browser cookie to activate debug logging. Debug logs are no longer filled with ENTERING_MANAGED_PKG events when your log level for the Apex Code category is INFO or DEBUG. ISVs now get a free ISV Customer Debugger session, even if they’ve purchased Apex Debugger sessions. New and updated event types let you troubleshoot issues regarding accessing external object data.
