For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 2.10.0 **`(feat):`** Support streaming response bodies in generated PHP SDKs (Server-Sent Events, NDJSON, and raw text). Endpoints with a `response-stream` now return a typed `SseStream`, `JsonStream`, or `TextStream` that iterates the response frame-by-frame and deserializes each one into the declared payload type. Previously these endpoints were emitted as broken `void` methods that always threw `ApiException` regardless of HTTP status. ## 2.9.7 **`(chore):`** Patch the bundled `ip-address` to v10.2.0 in the php-sdk container to address CVE-2026-42338 / GHSA-v2v4-37r5-5v8g (XSS in `Address6` HTML- emitting methods). npm 11.12.1 (shipped with `node:24.15`) bundles `ip-address@10.1.0` via `socks`; this overlays the published 10.2.0 tarball in place at image build time.
