This release hardens runtime option handling, adds RFC 9110 status-code aliases, fixes Node.js and XHR reliability issues, and refreshes project tooling and documentation.
⚠️ Breaking Changes & Deprecations
HTTP Status Naming: Added ContentTooLarge (413) and UnprocessableContent (422), while retaining PayloadTooLarge and UnprocessableEntity as backward-compatible deprecated aliases. (#11082)
🔒 Security Fixes
Runtime Option Handling: Hardened behavioral configuration reads against shared and foreign prototype pollution and normalized unsafe interceptor replacement objects. This also clarifies Fetch redirect and custom implementation behavior, HTTP/2 DNS and proxy handling, CIDR-based NO_PROXY matching, and malformed data URI rejection; see the PR for documented compatibility effects. (#11141)
🐛 Bug Fixes
Interceptor Lifecycle: Prevented unbounded handler-array growth by trimming trailing ejected interceptors without changing iteration semantics, and kept interceptor operations safe when the public handlers field is nullish. (#11087, #11118)
Request Error Preservation: Prevented custom Error.prepareStackTrace implementations that return non-string values from replacing the original request failure with an unrelated TypeError. (#11109)
XHR Reliability: Navigation-canceled requests now reject with ECONNABORTED instead of resolving with status 0, while successful downloads flush their final progress callback during the live loadend dispatch. (#11094, #11121)
Node.js Socket Memory: Removed request-context retention from per-socket error listeners, preventing completed response data from being pinned for the lifetime of pooled keep-alive sockets. (#11091)
Core Methods and HTTP Errors: Prevented structural method-header buckets from leaking into outgoing headers, standardized invalid DNS lookup and httpVersion failures as AxiosError.ERR_BAD_OPTION_VALUE, and corrected the timeoutErrorMessage merge strategy. (#11096)
Documentation: Applied the v1.19.0 documentation updates, added the missing fs import to the README stream example, introduced localized global search, and repaired the interceptor test link. (#11101, #11113, #11097, #11119)
Sponsorship: Updated sponsorship links and data and added ScrapingBee as a sponsor. (#11124, #11136, #11137)
CI and Release: Switched ESM smoke tests to locked dependencies and synchronized package and runtime version metadata for v1.20.0. (#11128, #11152)
🌟 New Contributors
We are thrilled to welcome our new contributors. Thank you for helping improve axios:
This release raises the form-data security floor, adds configuration and type-system capabilities, and fixes NO_PROXY matching, interceptor errors, progress reporting, and serialization edge cases.
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. (#10917, #10930, #10942, #10993)
Runtime and Type Correctness: Fixed several runtime crashes, type definition mismatches, and incorrect error handling paths. (#10959, #11021)
AxiosURLSearchParams: Switched the encoder callback to an arrow function so encoder.call(this) receives the AxiosURLSearchParams instance correctly. (#11019)
🔧 Maintenance & Chores
Documentation: Documented sensitive headers and status transition behaviour, prepared cleaned-up docs, added Deno install instructions, and clarified that request data is request-specific (#11007, #11010, #11023, #11025)
This release hardens redirect and URL handling, improves the validateStatus configuration semantics, and includes updates to documentation, dependencies, and release metadata.
This release adds Node HTTP zstd decompression, hardens config and release workflows, and fixes authentication, header, proxy, and type-handling regressions.
This release ships a defence-in-depth fix for prototype pollution in formDataToJSON, hardens proxy and CI workflows, restores Webpack 4 compatibility for the fetch adapter, and includes several small bug fixes and maintenance improvements.
This release adds support for the QUERY HTTP method and a new ECONNREFUSED error constant, lands a substantial wave of HTTP, fetch, and XHR adapter bug fixes around redirects, aborts, headers, and timeouts, and welcomes 23 new contributors.
This release delivers prototype-pollution hardening for the Node HTTP adapter, adds an opt-in allowedSocketPaths allowlist to mitigate SSRF via Unix domain sockets, fixes a keep-alive socket memory leak, and ships supply-chain hardening across CI and security docs.
This release ships a coordinated set of security hardening fixes across headers, body/redirect limits, multipart handling, and XSRF/prototype-pollution vectors, alongside a broad sweep of bug fixes, test migrations, and threat-model documentation updates.
Added a clear() function to the request and response interceptors object so a user can ensure that all interceptors have been removed from an axios instance #4248
There are multiple deprecations, refactors and fixes provided in this release. Please read through the full release notes to see how this may impact your project and use case.
Removed
Removed incorrect argument for NetworkError constructor #4656
