mitmproxy v12.0.0

New Contentview System (#7623, @mhils)

• Contentviews can now be interactive and re-encode prettified data. For example, the new Protobuf view pretty-prints to YAML, which the user can edit and then re-serialize into binary representation.
• Replace the existing gRPC and Protobuf contentviews with an interactive contentview that supports both existing proto definitions and completely unknown protos.
• The MsgPack contentview is now interactive, too.
• The contentview API has been drastically simplified. Contentviews now return a plain str with the prettified data. Syntax highlighting is now signaled off-band (and based on tree-sitter).
• Docs: Add new documentation page and API reference for contentviews.
• Contentviews can now be written in Rust for better performance and access to the crates ecosystem.
