<ul class="simple">
<li>WebOb’s exceptions will lazily read underlying variables when inserted into
templates to avoid expensive computations/crashes when inserting into the
template. This had a bad performance regression on Py27 because of the way
the lazified class was created and returned. See

<li>Response.from_file now parses the status line correctly when the status line
contains an HTTP with version, as well as a status text that contains
multiple white spaces (e.g 404 Not Found). See

<ul class="simple">
<li>Request.decode attempted to read from the an already consumed stream, it has
now been redirected to another stream to read from. See
<a class="reference external" href="https://github.com/Pylons/webob/pull/183">https://github.com/Pylons/webob/pull/183</a></li>
<li>The application/json media type does not allow for a charset as discovery of
the encoding is done at the JSON layer. Upon initialization of a Response
WebOb will no longer add a charset if the content-type is set to JSON. See
<a class="reference external" href="https://github.com/Pylons/webob/pull/197">https://github.com/Pylons/webob/pull/197</a> and

<div class="section" id="features">
<h3>Features<a class="headerlink" href="#features" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Lazily HTML escapes environment keys in HTTP Exceptions so that those keys in
the environ that are not used in the output of the page don’t raise an
exception due to inability to be properly escaped. See
<a class="reference external" href="https://github.com/Pylons/webob/pull/139">https://github.com/Pylons/webob/pull/139</a></li>
<li>MIMEAccept now accepts comparisons against wildcards, this allows one to
match on just the media type or sub-type, without having to explicitly match
on both the media type and sub-type at the same time. See
<a class="reference external" href="https://github.com/Pylons/webob/pull/185">https://github.com/Pylons/webob/pull/185</a></li>
<li>Add the ability to return a JSON body from an exception. Using the Accept
information in the request, the exceptions will now automatically return a
JSON version of the exception instead of just HTML or text. See
<a class="reference external" href="https://github.com/Pylons/webob/pull/230">https://github.com/Pylons/webob/pull/230</a> and
<a class="reference external" href="https://github.com/Pylons/webob/issues/209">https://github.com/Pylons/webob/issues/209</a></li>

</div>
<div class="section" id="security">
<h3>Security<a class="headerlink" href="#security" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>exc._HTTPMove and any subclasses will now raise a ValueError if the location
field contains a line feed or carriage return. These values may lead to
possible HTTP Response Splitting. The header_getter descriptor has also been
modified to no longer accept headers with a line feed or carriage return.
See: <a class="reference external" href="https://github.com/Pylons/webob/pull/229">https://github.com/Pylons/webob/pull/229</a> and

<h3>Bug Fixes<a class="headerlink" href="#bug-fixes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>The exceptions HTTPNotAcceptable, HTTPUnsupportedMediaType and
HTTPNotImplemented will now correctly use the sub-classed template rather
than the default error template. See <a class="reference external" href="https://github.com/Pylons/webob/issues/221">https://github.com/Pylons/webob/issues/221</a></li>
<li>Response’s from_file now correctly deals with a status line that contains an
HTTP version identifier. HTTP/1.1 200 OK is now correctly parsed, whereas
before this would raise an error upon setting the Response.status in
from_file. See <a class="reference external" href="https://github.com/Pylons/webob/issues/121">https://github.com/Pylons/webob/issues/121</a></li>

then the reason. See <a class="reference external" href="https://github.com/Pylons/webob/pull/191">https://github.com/Pylons/webob/pull/191</a></li>

to support bodies. See <a class="reference external" href="https://github.com/Pylons/webob/pull/184">https://github.com/Pylons/webob/pull/184</a></li>
<li>Response.from_file returns HTTP headers as latin1 rather than UTF-8, this

<h3>Features<a class="headerlink" href="#id20" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Added a read-only <code class="docutils literal"><span class="pre">domain</span></code> property to <code class="docutils literal"><span class="pre">BaseRequest</span></code>. This property
returns the domain portion of the host value. For example, if the
environment contains an <code class="docutils literal"><span class="pre">HTTP_HOST</span></code> value of <code class="docutils literal"><span class="pre">foo.example.com:8000</span></code>,
<code class="docutils literal"><span class="pre">request.domain</span></code> will return <code class="docutils literal"><span class="pre">foo.example.com</span></code>.</li>
<li>Added five new APIs: <code class="docutils literal"><span class="pre">webob.cookies.CookieProfile</span></code>,
<code class="docutils literal"><span class="pre">webob.cookies.SignedCookieProfile</span></code>, <code class="docutils literal"><span class="pre">webob.cookies.JSONSerializer</span></code> and
<code class="docutils literal"><span class="pre">webob.cookies.SignedSerializer</span></code>, and <code class="docutils literal"><span class="pre">webob.cookies.make_cookie</span></code>. These
APIs are convenience APIs for generating and parsing cookie headers as well
as dealing with signing cookies.</li>
<li>Cookies generated via webob.cookies quoted characters in cookie values that
did not need to be quoted per RFC 6265. The following characters are no
longer quoted in cookie values: <code class="docutils literal"><span class="pre">~/=<>()[]{}?@</span></code> . The full set of
non-letter-or-digit unquoted cookie value characters is now
<code class="docutils literal"><span class="pre">!#$%&'*+-.^_`|~/:</span> <span class="pre">=<>()[]{}?@</span></code>. See
<a class="reference external" href="http://tools.ietf.org/html/rfc6265#section-4.1.1">http://tools.ietf.org/html/rfc6265#section-4.1.1</a> for more information.</li>
<li>Cookie names are now restricted to the set of characters expected by RFC
6265. Previously they could contain unsupported characters such as <code class="docutils literal"><span class="pre">/</span></code>.</li>
<li>Older versions of Webob escaped the doublequote to <code class="docutils literal"><span class="pre">\"</span></code> and the backslash
to <code class="docutils literal"><span class="pre">\\</span></code> when quoting cookie values. Now, instead, cookie serialization
generates <code class="docutils literal"><span class="pre">\042</span></code> for the doublequote and <code class="docutils literal"><span class="pre">\134</span></code> for the backslash. This
is what is expected as per RFC 6265. Note that old cookie values that do
have the older style quoting in them will still be unquoted correctly,
however.</li>
<li>Added support for draft status code 451 (“Unavailable for Legal Reasons”).

This is more similar to how <code class="xref py py-class docutils literal"><span class="pre">webob.Response</span></code> handles the

<li>Added method <code class="xref py py-meth docutils literal"><span class="pre">webob.Response.merge_cookies()</span></code>, which takes the
<code class="docutils literal"><span class="pre">Set-Cookie</span></code> headers from a Response, and merges them with another
response or WSGI application. (This is useful for flash messages.)</li>
<li>Fix a problem with creating exceptions like
<code class="docutils literal"><span class="pre">webob.exc.HTTPNotFound(body='<notfound/>',</span>
<span class="pre">content_type='application/xml')</span></code> (i.e., non-HTML exceptions).</li>
<li>When a Location header is not absolute in a Response, it will be
made absolute when the Response is called as a WSGI application.

they act more like normal response objects (despite not being
new-style classes or <code class="docutils literal"><span class="pre">webob.Response</span></code> objects). In Python 2.5 the
exceptions are <code class="docutils literal"><span class="pre">webob.Response</span></code> objects.</li>

<h3>Backward Incompatible Changes<a class="headerlink" href="#backward-incompatible-changes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>The <code class="docutils literal"><span class="pre">Response</span></code> constructor has changed: it is now <code class="docutils literal"><span class="pre">Response([body],</span>
<span class="pre">[status],</span> <span class="pre">...)</span></code> (before it was <code class="docutils literal"><span class="pre">Response([status],</span> <span class="pre">[body],</span> <span class="pre">...)</span></code>).
Body may be str or unicode.</li>
<li>The <code class="docutils literal"><span class="pre">Response</span></code> class defaults to <code class="docutils literal"><span class="pre">text/html</span></code> for the
Content-Type, and <code class="docutils literal"><span class="pre">utf8</span></code> for the charset (charset is only set on
<code class="docutils literal"><span class="pre">text/*</span></code> and <code class="docutils literal"><span class="pre">application/*+xml</span></code> responses).</li>

<h3>Bugfixes and Small Changes<a class="headerlink" href="#bugfixes-and-small-changes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Use <code class="docutils literal"><span class="pre">BaseCookie</span></code> instead of <code class="docutils literal"><span class="pre">SimpleCookie</span></code> for parsing cookies.</li>
<li>Added <code class="docutils literal"><span class="pre">resp.write(text)</span></code> method, which is equivalent to
<code class="docutils literal"><span class="pre">resp.body</span> <span class="pre">+=</span> <span class="pre">text</span></code> or <code class="docutils literal"><span class="pre">resp.unicode_body</span> <span class="pre">+=</span> <span class="pre">text</span></code>, depending on
the type of <code class="docutils literal"><span class="pre">text</span></code>.</li>
<li>The <code class="docutils literal"><span class="pre">decode_param_names</span></code> argument (used like
<code class="docutils literal"><span class="pre">Request(decode_param_names=True)</span></code>) was being ignored.</li>
<li>Unicode decoding of file uploads and file upload filenames were
causing errors when decoding non-file-upload fields (both fixes from
Ryan Barrett).</li>
</ul>
</div>
</div>
<div class="section" id="id51">
<h2>0.8.5<a class="headerlink" href="#id51" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>Added response methods <code class="docutils literal"><span class="pre">resp.encode_content()</span></code> and
<code class="docutils literal"><span class="pre">resp.decode_content()</span></code> to gzip or ungzip content.</li>
<li><code class="docutils literal"><span class="pre">Response(status=404)</span></code> now works (before you would have to use
<code class="docutils literal"><span class="pre">status="404</span> <span class="pre">Not</span> <span class="pre">Found"</span></code>).</li>
<li>Bugfix (typo) with reusing POST body.</li>
<li>Added <code class="docutils literal"><span class="pre">226</span> <span class="pre">IM</span> <span class="pre">Used</span></code> response status.</li>
<li>Backport of <code class="docutils literal"><span class="pre">string.Template</span></code> included for Python 2.3
compatibility.</li>
</ul>
</div>
<div class="section" id="id52">
<h2>0.8.4<a class="headerlink" href="#id52" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li><code class="docutils literal"><span class="pre">__setattr__</span></code> would keep <code class="docutils literal"><span class="pre">Request</span></code> subclasses from having
properly settable environ proxies (like <code class="docutils literal"><span class="pre">req.path_info</span></code>).</li>
</ul>
</div>
<div class="section" id="id53">
<h2>0.8.3<a class="headerlink" href="#id53" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li><code class="docutils literal"><span class="pre">request.POST</span></code> was giving FieldStorage objects for <em>every</em>
attribute, not just file uploads. This is fixed now.</li>
<li>Added request attributes <code class="docutils literal"><span class="pre">req.server_name</span></code> and <code class="docutils literal"><span class="pre">req.server_port</span></code>
for the environ keys <code class="docutils literal"><span class="pre">SERVER_NAME</span></code> and <code class="docutils literal"><span class="pre">SERVER_PORT</span></code>.</li>
<li>Avoid exceptions in <code class="docutils literal"><span class="pre">req.content_length</span></code>, even if
<code class="docutils literal"><span class="pre">environ['CONTENT_LENGTH']</span></code> is somehow invalid.</li>
</ul>

<h2>0.8.2<a class="headerlink" href="#id54" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>Python 2.3 compatibility: backport of <code class="docutils literal"><span class="pre">reversed(seq)</span></code></li>
<li>Made separate <code class="docutils literal"><span class="pre">.exception</span></code> attribute on <code class="docutils literal"><span class="pre">webob.exc</span></code> objects,
since new-style classes can’t be raised as exceptions.</li>
<li>Deprecate <code class="docutils literal"><span class="pre">req.postvars</span></code> and <code class="docutils literal"><span class="pre">req.queryvars</span></code>, instead using the
sole names <code class="docutils literal"><span class="pre">req.GET</span></code> and <code class="docutils literal"><span class="pre">req.POST</span></code> (also <code class="docutils literal"><span class="pre">req.str_GET</span></code> and
<code class="docutils literal"><span class="pre">req.str_POST</span></code>). The old names give a warning; will give an error
in next release, and be completely gone in the following release.</li>
<li><code class="docutils literal"><span class="pre">req.user_agent</span></code> is now just a simple string (parsing the
User-Agent header was just too volatile, and required too much
knowledge about current browsers). Similarly,
<code class="docutils literal"><span class="pre">req.referer_search_query()</span></code> is gone.</li>
<li>Added parameters <code class="docutils literal"><span class="pre">version</span></code> and <code class="docutils literal"><span class="pre">comment</span></code> to
<code class="docutils literal"><span class="pre">Response.set_cookie()</span></code>, per William Dode’s suggestion.</li>
<li>Was accidentally consuming file uploads, instead of putting the
<code class="docutils literal"><span class="pre">FieldStorage</span></code> object directly in the parameters.</li>
</ul>
</div>
<div class="section" id="id55">
<h2>0.8.1<a class="headerlink" href="#id55" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>Added <code class="docutils literal"><span class="pre">res.set_cookie(...,</span> <span class="pre">httponly=True)</span></code> to set the <code class="docutils literal"><span class="pre">HttpOnly</span></code>
attribute on the cookie, which keeps Javascript from reading the
cookie.</li>
<li>Added some WebDAV-related responses to <code class="docutils literal"><span class="pre">webob.exc</span></code></li>
<li>Set default <code class="docutils literal"><span class="pre">Last-Modified</span></code> when using <code class="docutils literal"><span class="pre">response.cache_expire()</span></code>
(fixes issue with Opera)</li>
<li>Generally fix <code class="docutils literal"><span class="pre">.cache_control</span></code></li>
