Release date: March 25, 2025
Change server information endpoint / to only accept GET and HEAD requests
This will surface any agent misconfiguration causing data to be sent to / instead of the correct endpoint, e.g. /v1/traces for OTLP/HTTP.
For more information, check PR #15976.
Impact
Any methods other than GET and HEAD to / will return HTTP 405 Method Not Allowed.
Action
Update any existing usage of e.g. POST / to GET /.
