Big Release

posthog-elixir is now officially stable and running on v1. There are some breaking changes and some general improvements. Check MIGRATION.md for a guide on how to migrate.

What's changed

• Elixir v1.14+ is now a requirement
• Feature Flags now return a key called payload rather than value to better align with the other SDKs
• PostHog now requires you to initialize Posthog.Application alongside your supervisor tree. This is required because of our Cachex system to properly track your FF usage.
  • We'll also include local evaluation in the near term, which will also require a GenServer, therefore, requiring us to use a Supervisor.
• Added enabled_capture configuration option to disable PostHog tracking in development/test environments
• PostHog.capture now requires distinct_id as a required second argument
