All notable changes to Chainlit will be documented in this file.

The format is based on Keep a Changelog.

[1.3.2] - 2024-11-08

Security Advisory

IMPORTANT:

  • This release drops support for FastAPI versions before 0.115.3 and Starlette versions before 0.41.2 due to a severe security vulnerability (CVE-2024-47874). We strongly encourage all downstream dependencies to upgrade as well.
  • This release still contains a known security vulnerability in the element feature that could allow unauthorized file access. We strongly recommend against using elements in production environments until a comprehensive fix is implemented in an upcoming release.

Security

  • [breaking] Updated dependencies to address critical issues (#1493):
    • Upgraded fastapi to 0.115.3 to address CVE-2024-47874 in Starlette
    • Upgraded starlette to 0.41.2 (required for security fix)
    • Upgraded werkzeug to 3.0.6

Note: This is a breaking change as older FastAPI versions are no longer supported. To prioritize security, we opted to break with semver on this particular occasion.

Fixed

  • Resolved incorrect message ordering in UI (#1501)
