The OpenTelemetry Java agent 3.0 renames your metrics and ships GA this month

Version 2.32.0 of the OpenTelemetry Java agent, released on October 6, 2026, serves as the release candidate for 3.0, which is slated to go stable this month: attribute names, units, and trace shapes all change. Turn on dual emission with the /dup flag and compare your telemetry before the new schema becomes the default.
