Twisted Web 16.0.0 (2016-03-10)
===============================

Features
--------
 - twisted.web.http_headers._DictHeaders now correctly handles
   updating via keyword arguments in Python 3 (therefore
   twisted.web.http_headers is now fully ported to Python 3). (#6082)
 - twisted.web.wsgi has been ported to Python 3. (#7993)
 - twisted.web.http_headers.Headers now accepts both Unicode and
   bytestring keys and values, encoding to iso-8859-1 and utf8
   respectively. (#8129)
 - twisted.web.vhost ported to Python 3. (#8132)

Bugfixes
--------
 - twisted.web.http.HTTPChannel now correctly handles non-ascii method
   name by returning 400. Previously non-ascii method name was causing
   unhandled exceptions. (#8102)
 - twisted.web.static.File on Python 3 now redirects paths to
   directories without a trailing slash, to a path with a trailing
   slash, as on Python 2. (#8169)

Deprecations and Removals
-------------------------
 - twisted.web.http.Request's headers and request_headers attributes,
   deprecated since Twisted 13.2, have been removed. (#8136)
 - twisted.web.static.addSlash is deprecated. (#8169)

Other
-----
 - #8140, #8182


Twisted Web 15.5.0 (2015-11-28)
===============================

Features
--------
 - twisted.web.http.Request.addCookie now supports the httpOnly
   attribute which when set on cookies prevents the browser exposing
   it through channels other than HTTP and HTTPS requests (i.e. they
   will not be accessible through JavaScript). (#5911)
 - twisted.web.client.downloadPage is now ported to Python 3. (#6197)
 - twisted.web.client.Agent is now ported to Python 3. (#7407)
 - twisted.web.tap (ran when calling `twistd web`) has now been ported
   to Python 3. Not all features are enabled -- CGI, WSGI, and
   distributed web serving will be enabled in their respective tickets
   as they are ported. (#8008)

Bugfixes
--------
 - twisted.web.client.URI now supports IPv6 addresses. Previously this
   would mistake the colons used as IPv6 address group separators as
   the start of a port specification. (#7650)
 - twisted.web.util's failure template has been moved inline to work
   around Python 3 distribution issues. (#8047)

   cancelled. (#6686)

Deprecations and Removals
-------------------------
 - twisted.web.iweb.IRequest.getClient is now deprecated.  Its

   also deprecated and will no longer attempt to resolve the client IP
   address to a hostname. (#2252)

Other
-----
 - #7247, #7302, #7680, #7689


Twisted Web 14.0.2 (2014-09-18)
===============================

No significant changes have been made for this release.


Twisted Web 14.0.1 (2014-09-17)
===============================

Bugfixes
--------
 - BrowserLikePolicyForHTTPS would always ignore the specified
   trustRoot and use the system trust root instead, which has been
   rectified. (#7647)

===============================

Features
--------
 - twisted.web.http.proxiedLogFormatter can now be used with

   -Forwarded-For values to the access log when the HTTP server is
   deployed behind a reverse proxy. (#1468)
 - twisted.web.client.Agent now uses
   twisted.internet.ssl.CertificateOptions for SSL/TLS and benefits
   from its continuous improvements. (#6893)

Bugfixes
--------
 - twisted.web.client.Agent now correctly manage flow-control on
   pooled connections, and therefore requests will no longer hang
   sometimes when deliverBody is not called synchronously within the
   callback on Request. (#6751)
 - twisted.web.client.Agent now verifies that the provided server
   certificate in a TLS connection is trusted by the platform. (#7042)
 - When requesting an HTTPS URL with twisted.web.client.Agent, the
   hostname of the presented certificate will be checked against the
   requested hostname; mismatches will now result in an error rather
   than a man-in-the-middle opportunity for attackers.  This may break
   existing code that incorrectly depended on insecure behavior, but
   such code was erroneous and should be updated.  (#4888)

Other
-----
 - #5004, #6881, #6956


Twisted Web 13.2.0 (2013-10-29)
===============================

 - The deferred returned by twisted.web.client.Agent.request can now
   be cancelled. (#4330)
 - twisted.web.client.BrowserLikeRedirectAgent, a new redirect agent,
   treats HTTP 301 and 302 like HTTP 303 on non-HEAD/GET requests,
   changing the method to GET before proceeding. (#5434)
 - The new attribute twisted.web.iweb.IResponse.request is a reference
   to a provider of the new twisted.web.iweb.IClientRequest interface
   which, among other things, provides a way to access the request's
   absolute URI. It is now also possible to inspect redirect history
   with twisted.web.iweb.IResponse.previousResponse. (#5435)
 - twisted.web.client.RedirectAgent now supports relative URI
   references in the Location HTTP header. (#5462)
 - twisted.web.client now provides readBody to collect the body of a
   response from Agent into a string. (#6251)

 - twisted.web.http.HTTPChannel.headerReceived now catches the error
   if the Content-Length header is not an integer and return a 400 Bad
   Request response. (#6029)
 - twisted.web.http.HTTPChannel now drops the connection and issues a
   400 error upon receipt of a chunk-encoding encoded request with a
   bad chunk-length field. (#6030)

Improved Documentation
----------------------

   closed. (#3796)
 - twisted.web.server now omits the default Content-Type header from

   headers, although this is not yet usefully exposed to user code.
   (#4673)
 - twisted.web.client.Agent no longer raises an exception if a server
   responds and closes the connection before the request has been
   fully transmitted. (#5013)

-------------------------
 - twisted.web.google is now deprecated. (#5209)

Other
-----
 - #4951, #5057, #5175, #5288, #5316


Twisted Web 11.0.0 (2011-04-01)
===============================

Features
--------
 - twisted.web._newclient.HTTPParser (and therefore Agent) now handles
   HTTP headers delimited by bare LF newlines. (#3833)
 - twisted.web.client.downloadPage now accepts the `afterFoundGet`
   parameter, with the same meaning as the `getPage` parameter of the
   same name. (#4364)
 - twisted.web.xmlrpc.Proxy constructor now takes additional 'timeout'
   and 'reactor' arguments. The 'timeout' argument defaults to 30
   seconds. (#4741)

   the default for that scheme. (#3857)
 - twisted.web.http.Request.write now raises an exception if it is
   called after response generation has already finished. (#4317)
 - twisted.web.client.HTTPPageGetter and twisted.web.client.getPage

 - twisted.web will now properly specify an encoding (UTF-8) on error,
   redirect, and directory listing pages, so that IE7 and previous
   will not improperly guess the 'utf7' encoding in these cases.
   Please note that Twisted still sets a *default* content-type of
   'text/html', and you shouldn't rely on that: you should set the
   encoding appropriately in your application. (#4900)
 - twisted.web.http.Request.setHost now sets the port in the host
   header if it is not the default. (#4918)
 - default NOT_IMPLEMENTED and NOT_ALLOWED pages now quote the request
   method and URI respectively, to protect against browsers which
   don't quote those values for us. (#4978)

===============================

Features
--------
 - twisted.web.xmlrpc.XMLRPC.xmlrpc_* methods can now be decorated
   using withRequest to cause them to be passed the HTTP request
   object. (#3073)

Bugfixes
--------
 - twisted.web.xmlrpc.QueryProtocol.handleResponse now disconnects
   from the server, meaning that Twisted XML-RPC clients disconnect
   from the server as soon as they receive a response, rather than
   relying on the server to disconnect. (#2518)
 - twisted.web.twcgi now generates responses containing all
   occurrences of duplicate headers produced by CGI scripts, not just
   the last value. (#4742)

Deprecations and Removals

   doc/web/howto/client.xhtml. (#4507)

Deprecations and Removals
-------------------------
 - twisted.web.twcgi.PHP3Script and twisted.web.twcgi.PHPScript are
   now deprecated. (#516)

   contained examples on a range of common web topics, is now a part
   of the Twisted Web howto documentation. (#4192)

Bugfixes
--------
 - Data and File from twisted.web.static and
   twisted.web.distrib.UserDirectory will now only generate a 200
   response for GET or HEAD requests.
   twisted.web.client.HTTPPageGetter will no longer ignore the case of

   processing to a response. (#446)

 - twisted.web.http.HTTPClient now supports multi-line headers.
   (#2062)

 - Resources served via twisted.web.distrib will no longer encounter a
   Banana error when writing more than 640kB at once to the request
   object. (#3212)

 - The Error, PageRedirect, and InfiniteRedirection exception in
   twisted.web now initialize an empty message parameter by mapping
   the HTTP status code parameter to a descriptive string. Previously
   the lookup would always fail, leaving message empty.  (#3806)

 - The 'wsgi.input' WSGI environment object now supports -1 and None
   as arguments to the read and readlines methods. (#4114)

 - twisted.web.wsgi doesn't unquote QUERY_STRING anymore, thus
   complying with the WSGI reference implementation. (#4143)

 - The HTTP proxy will no longer pass on keep-alive request headers
   from the client, preventing pages from loading then "hanging"
   (leaving the connection open with no hope of termination). (#4179)

Deprecations and Removals
-------------------------
 - Remove '--static' option from twistd web, that served as an alias
   for the '--path' option. (#3907)

Other
-----

 - The HTTP auth support in the web server now allows anonymous sessions by
   logging in with ANONYMOUS credentials when no Authorization header is
   provided in a request (#3924, #3936)
 - HTTPClientFactory now accepts a parameter to enable a common deviation from
   the HTTP 1.1 standard by responding to redirects in a POSTed request with a
   GET instead of another POST (#3624)
 - A new basic HTTP/1.1 client API is included in twisted.web.client.Agent
   (#886, #3987)

Fixes
-----
 - Requests for "insecure" children of a static.File (such as paths containing
   encoded directory separators) will now result in a 404 instead of a 500
   (#3549, #3469)
 - When specifying a followRedirect argument to the getPage function, the state
   of redirect-following for other getPage calls should now be unaffected.  It
   was previously overwriting a class attribute which would affect outstanding
   getPage calls (#3192)
 - Downloading an URL of the form "http://example.com:/" will now work,
   ignoring the extraneous colon (#2402)
 - microdom's appendChild method will no longer issue a spurious warning, and
   microdom's methods in general should now issue more meaningful exceptions
   when invalid parameters are passed (#3421)
 - WSGI applications will no longer have spurious Content-Type headers added to
   their responses by the twisted.web server. In addition, WSGI applications
   will no longer be able to specify the server-restricted headers Server and
   Date (#3569)
 - http_headers.Headers now normalizes the case of raw headers passed directly
   to it in the same way that it normalizes the headers passed to setRawHeaders
   (#3557)
 - The distrib module no longer relies on the deprecated woven package (#3559)
 - twisted.web.domhelpers now works with both microdom and minidom (#3600)
 - twisted.web servers will now ignore invalid If-Modified-Since headers instead
   of returning a 500 error (#3601)
 - Certain request-bound memory and file resources are cleaned up slightly
   sooner by the request when the connection is lost (#1621, #3176)
 - xmlrpclib.DateTime objects should now correctly round-trip over twisted.web's
   XMLRPC support in all supported versions of Python, and errors during error
   serialization will no longer hang a twisted.web XMLRPC response (#2446)
 - request.content should now always be seeked to the beginning when
   request.process is called, so application code should never need to seek
   back manually (#3585)
 - Fetching a child of static.File with a double-slash in the URL (such as
   "example//foo.html") should now return a 404 instead of a traceback and
   500 error (#3631)
 - downloadPage will now fire a Failure on its returned Deferred instead of
   indicating success when the connection is prematurely lost (#3645)
 - static.File will now provide a 404 instead of a 500 error when it was
   constructed with a non-existent file (#3634)
 - microdom should now serialize namespaces correctly (#3672)
 - The HTTP Auth support resource wrapper should no longer corrupt requests and
   cause them to skip a segment in the request path (#3679)
 - The twisted.web WSGI support should now include leading slashes in PATH_INFO,
   and SCRIPT_NAME will be empty if the application is at the root of the
   resource tree. This means that WSGI applications should no longer generate
   URLs with double-slashes in them even if they naively concatenate the values
   (#3721)
 - WSGI applications should now receive the requesting client's IP in the
   REMOTE_ADDR environment variable (#3730)

   refactoring of twisted.web's header support (#3697)
 - static.File now supports multiple ranges specified in the Range header
   (#3574)
 - static.File should now generate a correct Content-Length value when the
   requested Range value doesn't fit entirely within the file's contents (#3814)
 - Attempting to call request.finish() after the connection has been lost will
   now immediately raise a RuntimeError (#4013)
 - An HTTP-auth resource should now be able to directly render the wrapped
