v1.18.1 — June 21, 2026
This release focuses on Node HTTP adapter fixes, safer AxiosError serialisation, runtime/type correctness fixes, documentation updates, and dependency maintenance.
🐛 Bug Fixes
- AxiosError Serialisation: Made AxiosError#cause non-enumerable to prevent circular JSON serialisation failures when errors include nested causes. (#10913)
- Node HTTP Adapter: Guarded socket.setKeepAlive for proxy agent streams, accepted path-only URLs when socketPath is configured, deferred environment proxy handling to Node, and explicitly passed maxBodyLength through to follow-redirects. (, , , )
