YARP's Release History: What Changed from 1.0 to 2.3 and Reading Old Configurations
YARP 2.3 (February 2025) is still the latest release in November 2026; array routes and old policy names from pre-1.0 configs stop the app from starting, but old fields such as HttpRequest.Timeout are silently ignored. We collect the defaults that changed from 1.0 to 2.3 from the release notes, read an old config with 2.3 and its JSON schema, and move an Ocelot-based gateway to YARP, comparing both sides with the same requests.
