3.82.0
(feat): Add webhook signature verification configuration to the IR. Webhooks can now
specify a signature block (in Fern Definition) or x-fern-webhook-signature
extension (in OpenAPI) with algorithm, encoding, header name, and payload format.
SDK generators can use this to produce signature verification utilities.
(feat): Add terminator field support for SSE streaming throughout the OpenAPI to Fern pipeline.
The field was already present in the Fern definition schema but missing from the OpenAPI
extension parsing, OpenAPI-IR schema, and the OpenAPI-IR to Fern conversion layers.
3.81.1
(fix): Fix example object keys starting with $ (e.g. $ref) not being unescaped when
generating the IR jsonExample. The Fern definition escapes $-prefixed keys with
a backslash to avoid collision with example references, but the backslash was not
removed when building the wire-format JSON example, causing generators to emit
invalid code (e.g. "\$ref" in Go).
3.81.0
(feat): Add --skip-autorelease-disabled flag to fern generator upgrade. When passed,
generators with autorelease: false in their configuration are skipped during
the upgrade. Skipped generators are reported in the output summary.
