Update Information:

Update to 0.38.0 (rhbz#2447261)
Filename sanitization for path traversal prevention — Added sanitize_filename()
to prevent path traversal attacks via malicious filenames in multipart uploads
(83e98a2)
Symlink protection in static file server — Static file serving now detects and
rejects symlinks that point outside the mount directory, preventing symlink-
based directory traversal (f787f31)
Brotli compression support — Added Brotli (br) as a supported content encoding
alongside gzip and deflate (ec1ffbc)
Accept-Encoding quality parameter parsing — The server now parses q= quality
values in the Accept-Encoding header and selects the best encoding accordingly
(bb7c7ab)
SSL proxy connection support — SSLClient can now establish connections through
HTTPS proxies, with a new setup_proxy_connection method for cleaner proxy
handling (f6ed5fc, b1bb2b7)
WebSocket ping interval runtime configuration — WebSocket ping interval can now
be configured at runtime instead of only at compile time (257b266)
Benchmark test suite — Added benchmark tests and configurations for performance
evaluation (ba0d0b8)
Unicode path component decoding tests — Added test coverage for Unicode
characters in decode_path_component (43a54a3)
Documentation updates — Enhanced TLS backend documentation with platform-
specific certificate handling details; clarified progress callback usage and
user data handling in examples (511e3ef, 2e61fd3)
Fix port conflict in test — Fixed port number in
OpenStreamMalformedContentLength test to avoid conflicts (4978f26)
Removed large data tests for GzipDecompressor and SSLClientServerTest that
