Charles Proxy: alte Versionen herunterladen

Bug fixes
- Session importing fixes; faults existed if keys were in an unexpected order across Charles-native and HAR import formats.

Minor new features
- Map Remote: new Preserve base path option stops a destination base path being applied twice when you map to a URL that has a base path (for example a backend mounted under a sub-path that emits absolute URLs already in that path-space). On by default; the checkbox is only enabled when the Map To location has a path.
Minor improvements
- Windows: every bundled binary is now codesigned to improve interaction with Windows Defender Application Control (WDAC) policies.
Bug fixes
- Several Map Remote fixes for tunnelled (HTTPS) requests: the destination path is now applied, the original location is reported, an HTTPS to HTTP mapping no longer attempts a TLS handshake with a plain HTTP server, and the requested port is restored from the SNI on a mapped CONNECT
- Fix for tool configurations that were lost when migrating settings from Charles 4 to Charles 5 (Windows & Linux)
- Fix a rare keep-alive liveness probe that could corrupt the remote stream
- Fix rare throttling bugs that could lead to incorrect throttling under some conditions
- Further HTTP/2 proxying correctness and robustness fixes: trailers forwarded (such as gRPC), connection flow-control accounting and frame-size validation, stream concurrency and lifecycle handling, and send-window stall detection
- HTTP/1.x improvements for chunked trailers
- Improve Repeat behaviour after failed connects
- SOCKS5 method negotiation and version handling now more accurate follows the specification
- Improve SSL handshake handling, certificate cache, and TLS extension parsing
- Log timestamps on stdout and now at millisecond precision
- HAR export no longer produces invalid output when containing unsupported encoded bodies

The 5.1.1b series has been released as 5.2 due to the scope of changes.
Major improvements
- Faster and more reliable connections to dual-stack hosts using Happy Eyeballs (RFC 8305) connection establishment
- Forward 1xx interim responses, including 103 Early Hints, recorded as linked transactions
- Many HTTP/2 proxying correctness and robustness improvements (see bug fixes)
Minor improvements
- New Unencrypted filter in the sequence view
- Improved sequence view filtering performance
- Improve expansion handling on the Structure view when using the filter
- New icons in the JSON and XML tree viewers
- Windows: JNA DLL is now codesigned
- Rewrite tool response status rewrite now works on HTTP2 responses
- Improved detection of text bodies for rewrite rules
- Rewrite the SSL certificate name when DNS Spoofing or the Rewrite tool changes the destination
- Recognise more TLS 1.3 draft minor versions and HTTP/3 draft version strings
- Propagate TCP half-close through tunnelled connections
- Flatlaf 3.7 for minor UI fixes & improvements on Linux and Windows
- New charles filter CLI subcommand for filtering requests and responses from saved Charles sessions
- --debug launch option to enable debug-level logging
- Allow saving the Error Log and streaming it to a file (right-click on Error Log)
Bug fixes
