17 May 2018: mitmproxy 4.0.1
** Bugfixes **
* The previous release had a packaging issue, so we bumped it to v4.0.1 and re-released it.
* This contains no actual bugfixes or new features.
17 May 2018: mitmproxy 4.0
** Features **
* mitmproxy now requires Python 3.6!
* Moved the core to asyncio - which gives us a very significant performance boost!
* Reduce memory consumption by using `SO_KEEPALIVE` (#3076)
* Export request as httpie command (#3031)
* Configure mitmproxy console keybindings with the keys.yaml file. See docs for more.
** Breaking Changes **
* The --conf command-line flag is now --confdir, and specifies the mitmproxy configuration
directory, instead of the options yaml file (which is at `config.yaml` under the configuration directory).
* `allow_remote` got replaced by `block_global` and `block_private` (#3100)
* No more custom events (#3093)
* The `cadir` option has been renamed to `confdir`

them to logs. Please use `` explicitly.
** Bugfixes **

26 December 2016: mitmproxy 1.0
* All mitmproxy tools are now Python 3 only! We plan to support Python 3.5 and higher.
* Web-Based User Interface: Mitmproxy now officially has a web-based user interface
called mitmweb. We consider it stable for all features currently exposed
in the UI, but it still misses a lot of mitmproxy’s options.
* Windows Compatibility: With mitmweb, mitmproxy is now usable on Windows.
We are also introducing an installer (kindly sponsored by BitRock) that
simplifies setup.
* Configuration: The config file format is now a single YAML file. In most cases,
converting to the new format should be trivial - please see the docs for
more information.
* Console: Significant UI improvements - including sorting of flows by
size, type and url, status bar improvements, much faster indentation for
HTTP views, and more.
* HTTP/2: Significant improvements, but is temporarily disabled by default
due to wide-spread protocol implementation errors on some large website
* WebSocket: The protocol implementation is now mature, and is enabled by
default. Complete UI support is coming in the next release. Hooks for
message interception and manipulation are available.
* A myriad of other small improvements throughout the project.

* Upstream certificate validation. See the --verify-upstream-cert,
--upstream-trusted-confdir and --upstream-trusted-ca parameters. Thanks to
Kyle Morton ( for his work on this.
* Add HTTP transparent proxy mode. This uses the host headers from HTTP
traffic (rather than SNI and IP address information from the OS) to
implement perform transparent proxying. Thanks to for
this feature.
* Add ~src and ~dst REGEX filters, allowing matching on source and
destination addresses in the form of <IP>:<Port>

Jose Luis Honorato (
* mitmproxy console: Flow marking and unmarking. Marked flows are not
deleted when the flow list is cleared. Thanks to Jake Drahos

* Remove the certforward feature. It was added to allow exploitation of
#gotofail, which is no longer a common vulnerability. Permitting this
hugely increased the complexity of packaging and distributing mitmproxy.

* mitmproxy console: A new options screen has been created ("o" shortcut),
and many options that were previously manipulated directly via a
keybinding have been moved there.
* mitmproxy console: Big improvement in palettes. This includes improvements
to all colour schemes. Palettes now set the terminal background colour by
default, and a new --palette-transparent option has been added to disable
* mitmproxy console: g/G shortcuts throughout mitmproxy console to jump
to the beginning/end of the current view.
* mitmproxy console: switch palettes on the fly from the options screen.
* mitmproxy console: A cookie editor has been added for mitmproxy console
at long last.

using the mitproxy cacert
* pathoc -S dumps information on the remote SSL certificate chain
* Big improvements to fuzzing, including random spec selection and memoization to avoid repeating randomly generated patterns

governing permitted file names are weird, resulting in errors for some
valid IDNA-encoded names.

expanding random and generated portions, and logging a reproducible
* Streamline the specification language. HTTP response message is now
specified using the "r" mnemonic.

generate interception certificates.
* Replacement patterns that let you easily do global replacements in flows

Support for auto-indentation of Javascript, inspection of image EXIF
data, and more.
* Details view for flows, showing connection and SSL cert information (X
keyboard shortcut).
* Server certificates are now stored and serialized in saved traffic for
later analysis. This means that the 0.8 serialization format is NOT
compatible with 0.7.
* Many other improvements, including bugfixes, and expanded scripting API,
and more sophisticated certificate handling.
20 February 2012: mitmproxy 0.7:

forwarding all traffic to a specified upstream server.
* UI improvements - use unicode characters to make GUI more compact,
improve spacing and layout throughout.
* Add support for filtering by HTTP method.

universal regex-based string replacement.
* Header management has been rewritten to maintain both case and order.
* Improved stability for SSL interception.
* Default expiry time on generated SSL certs has been dropped to avoid an
OpenSSL overflow bug that caused certificates to expire in the distant
past on some systems.
* A "pretty" view mode for JSON and form submission data.
* Expanded documentation and examples.
* Countless other small improvements and bugfixes.
27 June 2011: mitmproxy 0.5:

certificate is generated. This can pave over small discrepancies in
system time between the client and server.
* Handle viewing big request and response bodies more elegantly. Only
render the first 100k of large documents, and try to avoid running the
XML indenter on non-XML data.
* BUGFIX: Make the "revert" keyboard shortcut in mitmproxy work after a
flow has been replayed.
