I've just tagged and released mitmproxy 0.4. You can download it from the new project website:

mitmproxy.org

This is a huge update, with dozens of new features, and improvements to almost every aspect of the project. A few highlights are:

• Complete serialization of HTTP/S conversations
• On-the-fly generation of SSL interception certificates
• Ability to replay both the client and the server side of HTTP/S conversations
• mitmdump has grown up to be a powerful tcpdump-like commandline tool for HTTP/S
• Scripting hooks for programmatic modification of traffic using Python
• Many, many user interface improvements, bug fixes, and minor features
• Better documentation.

Special thanks go to Henrik Nordström for many great contributions to this release. I'd love more contributors to join the project - if you feel like hacking on mitmproxy, take a look at the todo file at the top of the tree for ideas.

Over the next week I will write a series of tutorials to showcase mitmproxy's abilities, ranging from simple to quite complex. Keep an eye on the blog for these - they will be published here first, before making their way into the official documentation.
