2026-02-27T15:35:19Z

This release focuses on platform compatibility, error handling improvements, and code quality maintenance.

⚠️ Important Changes

Breaking Changes: None identified in this release.
Action Required: Users targeting React Native should verify their integration, particularly if relying on specific Blob or FormData behaviours, as improvements have been made to support these objects.

🚀 New Features

React Native Blob Support: Axios now includes support for React Native Blob objects. Thanks to @moh3n9595 for the initial implementation. (#5764)
Code Quality: Implemented prettier across the codebase and resolved associated formatting issues. (#7385)

🐛 Bug Fixes

Environment Compatibility:
- Fixed module exports for React Native and Browserify environments. (#7386)
- Added safe FormData detection for the WeChat Mini Program environment. (#7324)
Error Handling:
- AxiosError.message is now correctly enumerable. (#7392)
- AxiosError.from now correctly copies the status property from the source error, ensuring better error propagation. (#7403)

🔧 Maintenance & Chores

Dependencies: Updated the development_dependencies group (5 updates). (#7432)
Infrastructure: Migrated @rollup/plugin-babel from v5.3.1 to v6.1.0. (#7424)

Release notes - v0.30.3

2026-02-18T17:20:54Z

This is a critical security maintenance release for the v0.x branch. It addresses a high-priority vulnerability involving prototype pollution that could lead to a Denial of Service (DoS).

Recommendation: All users currently on the 0.x release line should upgrade to this version immediately to ensure environment stability.

🛡️ Security Fixes

Backport: Fix DoS via proto key in merge config
- Patched a vulnerability where specifically crafted configuration objects using the proto key could cause a Denial of Service during the merge process. - by @FeBe95 in PR #7388

⚙️ Maintenance & CI

CI Infrastructure Update
- Updated Continuous Integration workflows for the v0.x branch to maintain long-term support and build reliability. - by @jasonsaayman in PR #7407

⚠️ Breaking Changes

Configuration Merging Behavior:

As part of the security fix, Axios now restricts the merging of the proto key within configuration objects. If your codebase relies on unconventional deep-merging patterns that target the object prototype via Axios config, those operations will now be blocked. This is a necessary change to prevent prototype pollution.
