5.155.1
(fix): Feature flag usage events ($feature_flag_called) now carry the properties the flag was
evaluated with (org, environment, generator, language) plus the CLI version, and are
sent once per generator instead of once per org, so PostHog can break flag usage down by
generator, language, and release environment.
5.155.0
(feat): fern docs dev now runs the Astro docs preview server by default, matching how published Fern Docs sites render.
Pass --legacy to run the previous Next.js preview server. --astro is still accepted but no longer needed,
and --beta is now a deprecated alias for --legacy. --private now applies to the Astro preview too.
The older pages-router preview server that --legacy used to start is no longer available.
5.154.2
(fix): Feature flag checks now report usage to PostHog ($feature_flag_called) when CLI telemetry
is enabled, so flags like use-sdk-gen-api show usage metrics. Setting
FERN_DISABLE_TELEMETRY=true still turns these events off; flag evaluation is unchanged.
5.154.1
(fix): Prevent the CLI from hanging indefinitely while flushing automation telemetry during exit.
5.154.0
(feat): Restore FERN_USE_SDK_GEN_API as a runtime override of the use-sdk-gen-api feature flag. true routes every
generator through sdk-gen-api and false keeps every generator off it (generation on Fiddle, generator upgrades on
FDR versions), without a flag request. Unset, or any other value, follows the flag. It is intended for tests and
debugging.
5.153.0
(feat): Add the layout.hide-webhook-method-badges docs.yml setting. When set to true,
webhook entries in the sidebar render without an HTTP method badge (e.g. POST),
so webhooks no longer read like callable endpoints. Defaults to false.
