CHANGELOG

21 February 2017: mitmproxy 2.0

    * HTTP/2 is now enabled by default.

    * Image ContentView: Parse images with Kaitai Struct (kaitai.io) instead of Pillow. 
      This simplifies installation, reduces binary size, and allows parsing in pure Python.

    * Web: Add missing flow filters.

    * Add transparent proxy support for OpenBSD.

    * Check the mitmproxy CA for expiration and warn the user to regenerate it if necessary.

    * Testing: Tremendous improvements, enforced 100% coverage for large parts of the 
      codebase, increased overall coverage.

    * Enforce individual coverage: one source file -> one test file with 100% coverage.

    * A myriad of other small improvements throughout the project.

    * Numerous 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 offically 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 useable 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.

24 July 2015: mitmproxy 0.13

    * Upstream certificate validation. See the --verify-upstream-cert,
      --upstream-trusted-cadir and --upstream-trusted-ca parameters. Thanks to
      Kyle Morton (github.com/kyle-m) 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 github.com/ijiro123 for
      this feature.

    * Add ~src and ~dst REGEX filters, allowing matching on source and
      destination addresses in the form of <IP>:<Port>

    * mitmproxy console: change g/G keyboard shortcuts to match less. Thanks to
      Jose Luis Honorato (github.com/jlhonora).

    * mitmproxy console: Flow marking and unmarking. Marked flows are not
      deleted when the flow list is cleared. Thanks to Jake Drahos
      (github.com/drahosj).

    * mitmproxy console: add marking of flows

    * 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.




3 June 2015: mitmproxy 0.12.1

    * mitmproxy console: mouse interaction - scroll in the flow list, click on
      flow to view, click to switch between tabs.

    * Update our crypto defaults: SHA256, 2048 bit RSA, 4096 bit DH parameters.

    * BUGFIX: crash under some circumstances when copying to clipboard.

    * BUGFIX: occasional crash when deleting flows.


18 May 2015: mitmproxy 0.12

    * mitmproxy console: Significant revamp of the UI. The major changes are
      listed below, and in addition almost every aspect of the UI has
      been tweaked, and performance has improved significantly.

    * 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
      this.

    * 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.

    * mitmproxy console: Various components of requests and responses can be
      copied to the clipboard from mitmproxy - thanks to @marceloglezer.

    * Support for creating new requests from scratch in mitmproxy console (@marceloglezer).

    * SSLKEYLOGFILE environment variable to specify a logging location for TLS
      master keys. This can be used with tools like Wireshark to allow TLS
      decoding.

    * Server facing SSL cipher suite specification (thanks to Jim Shaver).

    * Official support for transparent proxying on FreeBSD - thanks to Mike C
      (http://github.com/mike-pt).

    * Many other small bugfixes and improvemenets throughout the project.


29 Dec 2014: mitmproxy 0.11.2:

    * Configuration files - mitmproxy.conf, mitmdump.conf, common.conf in the
      .mitmproxy directory.
    * Better handling of servers that reject connections that are not SNI.

      contents or parameters when matching flows (marcelo.glezer@gmail.com)

    * Pass arguments to inline scripts

    * Configurable size limit on HTTP request and response bodies

    * Per-domain specification of interception certificates and keys (see
      --cert option)

    * Certificate forwarding, relaying upstream SSL certificates verbatim (see
      --cert-forward)

    * Search and highlighting for HTTP request and response bodies in
      mitmproxy console (pedro@worcel.com)

    * Transparent proxy support on Windows

    * Improved error messages and logging

    * Support for FreeBSD in transparent mode, using pf (zbrdge@gmail.com)

    * Content view mode for WBXML (davidshaw835@air-watch.com)

    * Better documentation, with a new section on proxy modes

    * Generic TCP proxy mode

    * Countless bugfixes and other small improvements

    * pathod: Hugely improved SSL support, including dynamic generation of certificates
    using the mitproxy cacert

7 November 2014: pathod 0.11:

  * Hugely improved SSL support, including dynamic generation of certificates
    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

  * Reflected patterns, allowing you to embed a pathod server response specification in a pathoc request, resolving both on client side. This makes fuzzing proxies and other intermediate systems much better.


28 January 2014: mitmproxy 0.10:

    * Support for multiple scripts and multiple script arguments

    * Easy certificate install through the in-proxy web app, which is now
      enabled by default

    * Forward proxy mode, that forwards proxy requests to an upstream HTTP server

    * Reverse proxy now works with SSL

      compatibility.

    * Fix a bug causing resource exhaustion under some circumstances for SSL
      connections.

    * Revamp the way we store interception certificates. We used to store these
      on disk, they're now in-memory. This fixes a race condition related to
      cert handling, and improves compatibility with Windows, where the rules
      governing permitted file names are weird, resulting in errors for some
      valid IDNA-encoded names.

    * Display transfer rates for responses in the flow list.

    * Many other small bugfixes and improvements.


25 August 2013: pathod 0.9.2:

    * Introduce netlib, a common codebase for mitmproxy and pathod
      (http://github.com/cortesi/netlib).

    * Full support for SNI.

    * Color palettes for mitmproxy, tailored for light and dark terminal
      backgrounds.

    * Stream flows to file as responses arrive with the "W" shortcut in
      mitmproxy.

    * Extend the filter language, including ~d domain match operator, ~a to
      match asset flows (js, images, css).

    * --dummy-certs option to specify and preserve the dummy certificate
      directory.

    * Server replay from the current captured buffer.

    * Huge improvements in content views. We now have viewers for AMF, HTML,
      JSON, Javascript, images, XML, URL-encoded forms, as well as hexadecimal
      and raw views.

    * Add Set Headers, analagous to replacement hooks. Defines headers that are set
      on flows, based on a matching pattern.

    * A graphical editor for path components in mitmproxy.

    * A small set of standard user-agent strings, which can be used easily in
      the header editor.

    * Proxy authentication to limit access to mitmproxy

      targets.

    * Pathoc client certificate support.

    * API improvements, bugfixes.


16 November 2012: pathod 0.3:

    A release focusing on shoring up our fuzzing capabilities, especially with
    pathoc.

    * pathoc -q and -r options, output full request and response text.

    * pathod -q and -r options, add full request and response text to pathod's
      log buffer.

    * pathoc and pathod -x option, makes -q and -r options log in hex dump
      format.

    * pathoc -C option, specify response codes to ignore.

    * pathoc -T option, instructs pathoc to ignore timeouts.

    * pathoc -o option, a one-shot mode that exits after the first non-ignored
      response.

    * pathoc and pathod -e option, which explains the resulting message by
      expanding random and generated portions, and logging a reproducible
      specification.

    * Streamline the specification langauge. HTTP response message is now
      specified using the "r" mnemonic.

    * Add a "u" mnemonic for specifying User-Agent strings. Add a set of

    * Add daemonization to Pathod, and make it more robust for public-facing use.

    * Let pathod pick an arbitrary open port if -p 0 is specified.

    * Move from Tornado to netlib, the network library written for mitmproxy.

    * Move the web application to Flask.

    * Massively expand the documentation.


5 April 2012: mitmproxy 0.8:

    * Detailed tutorial for Android interception. Some features that land in
      this release have finally made reliable Android interception possible.

    * Upstream-cert mode, which uses information from the upstream server to
      generate interception certificates.

    * Replacement patterns that let you easily do global replacements in flows
      matching filter patterns. Can be specified on the command-line, or edited
      interactively.

    * Much more sophisticated and usable pretty printing of request bodies.
      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:

    * New built-in key/value editor. This lets you interactively edit URL query
      strings, headers and URL-encoded form data.

    * Extend script API to allow duplication and replay of flows.

    * API for easy manipulation of URL-encoded forms and query strings.

    * Add "D" shortcut in mitmproxy to duplicate a flow.

    * Reverse proxy mode. In this mode mitmproxy acts as an HTTP server,
      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.

    * Add the ability to specify an HTTP body size limit.

    * Move to typed netstrings for serialization format - this makes 0.7
      backwards-incompatible with serialized data from 0.6!

    * Significant improvements in speed and responsiveness of UI.

    * Many minor bugfixes and improvements.


7 August 2011: mitmproxy 0.6:

    * New scripting API that allows much more flexible and fine-grained
      rewriting of traffic. See the docs for more info.

    * Support for gzip and deflate content encodings. A new "z"
      keybinding in mitmproxy to let us quickly encode and decode content, plus
      automatic decoding for the "pretty" view mode.

    * An event log, viewable with the "v" shortcut in mitmproxy, and the
      "-e" command-line flag in mitmdump.

    * Huge performance improvements: mitmproxy interface, loading
      large numbers of flows from file.

    * A new "replace" convenience method for all flow objects, that does a
      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:

    * An -n option to start the tools without binding to a proxy port.

    * Allow scripts, hooks, sticky cookies etc. to run on flows loaded from
      save files.

    * Regularize command-line options for mitmproxy and mitmdump.

    * Add an "SSL exception" to mitmproxy's license to remove possible
      distribution issues.

    * Add a --cert-wait-time option to make mitmproxy pause after a new SSL
      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.

    * BUGFIX: Repair a problem that sometimes caused SSL connections to consume
      100% of CPU.


30 March 2011: mitmproxy 0.4

    * Full serialization of HTTP conversations

    * Client and server replay

    * On-the-fly generation of dummy SSL certificates

    * mitmdump has "grown up" into a powerful tcpdump-like tool for HTTP/S

    * Dozens of improvements to the mitmproxy console interface

    * Filter expressions for terminal beeps, limits, interceptions and sticky
      cookies can now be passed on the command line.

    * Save requests and responses to file

    * Split off non-interactive dump functionality into a new tool called
      mitmdump

    * "A" will now accept all intercepted connections

    * Lots of bugfixes
