Major Changes

• #4705 dd5888a Thanks @ablaszkiewicz! - Change the default sourcemaps.releaseMode to event: set sourcemaps.releaseMode: 'symbol-set', or POSTHOG_RELEASE_MODE=symbol-set, to keep binding uploaded symbol sets to a release. The @posthog/plugin-utils bump is major, so an installed plugin keeps the old default until the plugin itself is upgraded.

  event mode requires a posthog-cli with release resolve and --release-mode, and posthog-js 1.409.0, posthog-node 5.47.0, or @posthog/core 1.46.0 at runtime. An older CLI fails a rollup build and skips the upload on webpack and Next.js. An older SDK reports no release on exceptions. (2026-09-02)
