@posthog/nextjs-config@1.11.0

1.11.0

Minor 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)

Patch Changes

• #4737 c589ab8 Thanks @cat-ph! - Bump @posthog/cli to ~0.16.2, which fixes a race in sourcemap process: inject and upload used to walk the directory roots separately, so a bundler still writing into the output directory mid-run (e.g. Turbopack's background filesystem-cache flush on Next.js 16.3+) could hand upload a chunk inject never stamped and abort the build with "Chunk ID not found". The CLI now uploads exactly the pairs it injected, and --delete-after cleanup skips files that vanished or changed after upload instead of failing the build.
