Changelog

April 28, 2026

5.8.3

(fix): Fix async SSE parsing to only split on SSE-spec line terminators (\n, \r, \r\n). Previously, aiter_sse() used httpx’s aiter_lines() which splits on \u2028 and \u2029 via Python’s str.splitlines(), corrupting data fields containing those characters (common in LLM JSON output).

5.8.2

(chore): Bump @fern-api/generator-cli to 0.9.16, which bundles the autoversion pipeline’s private workspace deps (@fern-api/logging-execa, @fern-api/task-context, @fern-api/cli-ai) into the published dist/api.js so consumers no longer hit ERR_MODULE_NOT_FOUND on logging-execa/src/createLoggingExecutable.js under Vite/Vitest.
