+
+All notable changes to the Annie documentation website will be documented in this file.
+
+## [Unreleased]
+
+### Changed
+
+- Updated urllib3 from 2.5.0 to 2.6.0 to address security vulnerabilities (CVE-2025-66471, CVE-2025-66418)
+- Added brotli>=1.2.0 dependency for enhanced security in HTTP content decompression
+- Ensures compatibility with urllib3 2.6.0's improved handling of decompression bombs and chained encodings
+- Dropped Python 3.9 support from CI testing (Python 3.9 reached end of life in October 2025, and newer dependencies require Python 3.10+)
+
+### Security
+
+- Fixed potential decompression bomb vulnerabilities through urllib3 2.6.0 update
+- Fixed potential DoS attack via unlimited chained encodings through urllib3 2.6.0 update
+- Added brotli 1.2.0+ for security fixes in brotli decompression
+
+### Notes
+
+- No code changes were required as the codebase does not use the deprecated urllib3 APIs (HTTPResponse.getheaders(), HTTPResponse.getheader())
+- The repository only uses urllib3 indirectly through the requests library
