Changelog for hs-opentelemetry-instrumentation-wai

Unreleased

1.0.0.0 - 2026-05-29

• Fix: initial span name is now low-cardinality. Previously used {method} {raw_path} which includes IDs, UUIDs, etc. Now uses just {method} (e.g. GET) until a framework sets the http.route attribute, at which point the name updates to {method} {route}.
• Add error.type attribute on 5xx responses (required by stable HTTP server conventions).
• Default server.port to 80/443 (based on scheme) when Host header omits port.
