PostHogTraceExporter now accepts projectToken

7.19.6

Patch Changes

• #3668 7c80b2e Thanks @rafaeelaudibert! - Expose projectToken in addition to apiKey for PostHogTraceExporter

  We're moving towards a place where we're calling this projectToken everywhere. Let's release this as a patch version because it's a tiny change and we still support the old usage. This might be dropped in the next packages/ai major version. (2026-05-28)
