5.7.3
(fix): Fix image path resolution on Windows for fern docs dev and fern generate docs.
Path utilities (resolve, dirname, join) now normalize output to forward slashes,
preventing file ID lookup mismatches caused by mixed path separators on Windows.
5.7.2
(fix): Allow BCP 47 locale tags (e.g. ja-JP, pt-BR, zh-Hans-CN) in the translations and languages fields of docs.yml. Previously these were rejected by the JSON-schema validator with must be one of [en, es, fr, ...].
5.7.1
(fix): Preserve OpenAPI default values for array schemas across query parameters,
headers, request bodies, and response body properties so docs can render
“Defaults to …” metadata for arrays.
5.7.0
(internal): cli-v2: introduce a shared stdin/stdout abstraction so commands uniformly honor
the Unix - marker on I/O flags (stdin for inputs, stdout for outputs), with a
“- used at most once per command” guard and a JSON-or-path input helper that
parses inline JSON first and falls back to a file read.
(internal): cli-v2: fern api compile --output - now uses the shared stdio helper (behavior
unchanged — still streams IR JSON to stdout).
(feat): cli-v2: fern sdk generate --api - and fern sdk preview --api - now read the
OpenAPI/AsyncAPI spec from stdin (e.g. cat openapi.json | fern sdk generate --api - --org acme --target typescript --output ./sdk).
(feat): cli-v2: fern api split --output - prints the generated overlay/overrides for
the matching spec to stdout as a preview, without modifying the workspace
(no git-HEAD restore, no fern.yml updates). Requires --api to select a single
spec.
5.6.1
(fix): Fix translated docs pages failing to resolve shared snippets (<Markdown src="..."/> and <Code src="..."/>).
Snippet references are now resolved before registering translations, with locale-aware loading that prefers
translated snippets (e.g., translations/zh/snippets/foo.mdx) when available.
5.6.0
(feat): Add fern automations upgrade command that wraps fern upgrade and
fern generator upgrade into a single invocation with structured JSON
output (--json). Designed for consumption by the fern-upgrade GitHub
Action.
(fix): Replace brittle hardcoded changelog URL map in upgradeGenerator.ts with
a regex-based derivation that supports all current and future generators.
