4.80.1
(fix): Display descriptions for discriminated and undiscriminated union variants.
4.80.0
(feat): Add fern automations preview command that discovers previewable generator
groups and runs SDK preview for each one, aggregating results. Replaces the
previous fern automations list preview listing-only command with a single
command that handles both discovery and execution. Designed for consumption
by the fern-preview GitHub Action.
