April 2026
April 2026 in OpenTelemetry: the Go Compile-Time Instrumentation SIG concludes its first year with three monthly releases and sets a June 1 target for v1.0.0, Global OTel Nights launches practitioner editions in Amsterdam and New York, three Collector releases deliver a critical azure_auth security fix, profiles signal promotion to alpha, a broad snake_case rename, and three new components including a log clustering processor. The specification formally deprecates OpenTracing and stabilizes Prometheus compatibility across virtually all metric types.
