<span id="releases"></span><h1>Release History<a class="headerlink" href="#release-history" title="Permalink to this headline">¶</a></h1>
<p>Historically, the release number of PyXB indicated stability in a way similar
to that of Linux several years ago, with even/odd of the middle digit
indicating stability/development. That policy ended as of 1.1.3, and the
relaxed policy is:</p>
<ul class="simple">
<li>All releases consist of three non-negative integers</li>
<li>A release <em>series</em> refers to all releases with the same first two integers.
The third integer indicates an incremental update to the system.</li>
<li>Should it be necessary to make wholesale changes that affect either
stability or interface, the second or even first integer will be
incremented</li>
<li>Critical bug fixes may result in new releases in older series, but this is
expected to be extremely unusual. Such fixes will be made on a branch of
the <a class="reference internal" href="maintref.html#git-repository"><span class="std std-ref">git repository</span></a>.</li>
<li>All packaged releases are intended to be of comparable stability, with bug
fixes and most enhancements causing an increment in the third integer</li>
</ul>
<p>As examples, <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/112/">correcting the content model for weak determinism</a>
resulted in PyXB 1.2.0, and <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/150/">support of Python 3</a> was completed
in PyXB 1.2.4. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/217/">support for XML Schema 1.1</a> will not be addressed
until PyXB 1.3.0 if at all.</p>
<div class="section" id="x">
<h2>1.2.x<a class="headerlink" href="#x" title="Permalink to this headline">¶</a></h2>
<p>The 1.2.x release series introduces a new content model which provides much
more help in resolving validation errors. Concurrent with this support was
dropped for Python 2.4 and 2.5. The 1.2.x release works with Python 2.6 and
2.7 and as of PyXB 1.2.4 also with Python 3.1 and later. Some unit tests are
skipped under Python 2.6 due to insufficient support for validating exception
attributes.</p>

<span id="pyxb-1-2-4"></span><h3>1.2.4 (19 Oct 2014)<a class="headerlink" href="#oct-2014" title="Permalink to this headline">¶</a></h3>
<p>Documentation: <a class="reference external" href="http://pyxb.sourceforge.net/PyXB-1.2.4">http://pyxb.sourceforge.net/PyXB-1.2.4</a></p>
<p>The major feature of this release is a new approach to Python 3 support based
on the <a class="reference external" href="https://pypi.python.org/pypi/six/">six</a> module. This resolves
<a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/150/">support for Python 3</a> and allows one release of PyXB to support
Python versions from 2.6 through 3.4, excluding 3.0. The <code class="docutils literal"><span class="pre">maintainer/2to3</span></code>
script used in PyXB 1.2.3 is no longer supported. Both the core
implementation and the bindings are compatible with Python 2 and 3.</p>
<p>A second important feature was correct handling of QName by changing the
binding representation from a string to an expanded name that saves the
namespace URI rather than the prefix from the original document.</p>
<p>Finally, with this release primary development and support moves from
SourceForge to <a class="reference external" href="https://github.com/pabigot/pyxb">Github</a>. Inter-release
updates will be made first on github (on the <a class="reference external" href="https://github.com/pabigot/pyxb/tree/next">next</a> branch), and pushed to the
SourceForge git repository aperiodically.</p>
<p>Other miscellanous changes:</p>
<ul class="simple">
<li>Correct rich comparisons for _PluralBinding instances. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/218/">SF ticket 218</a></li>
<li>Prevent adding non-element content as wildcard elements. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/219/">SF ticket 219</a></li>
<li>Provide public API to _CF_enumeration helper methods. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/221/">SF ticket 221</a></li>

<p>The Python 3 code in this branch is created by automatic conversion of the
Python 2 code using the maintainer/2to3 script. While not officially
supported until PyXB 1.3.0, Python 3 appears to work correctly with this
version.</p>
<p>Behavioral changes:</p>
<ul class="simple">
<li>PyXB 1.2.1 automatically filled in the content of fixed elements. This
generated invalid documents when the particular element should have been
absent for some content. The feature has been removed so fixed elements
initialize to absent just like every other element.</li>
<li>The former <cite>–pre-load-archives</cite> option to pyxbgen has been removed and
replaced by <a class="reference internal" href="pyxbgen_cli.html#pyxbgen-import-augmentable-namespace"><span class="std std-ref">–import-augmentable-namespace</span></a> which has more
consistent semantics. Schema import directives related to a non-augmentable
namespace (one for which the referenced option has not been provided) will
be ignored if content for the namespace can be located in any archive or
builtin.</li>
<li>Generating DOM (or XML) expressions of bindings that were created by type
constructors and not associated with elements now cause an exception to be
raised rather than mis-using the type name as though it were a valid element
tag.</li>
</ul>
<p>Code cleanup:</p>
<ul class="simple">
<li>Trailing whitespace throughout the source has been removed to decrease git
complaints and non-reproducible patches.</li>
<li>Several coding practices that would not work under Python3 have been
replaced with new solutions.</li>
</ul>
<p>The following reported <a class="reference external" href="http://sourceforge.net/p/pyxb/tickets/">defects/enhancements</a> have been addressed:</p>
<ul class="simple">
<li>Fix DOM style handling of xsi:type attribute. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/166/">SF ticket 166</a></li>

<p>Key features of the release:</p>
<ul class="simple">
<li>A large number of bug fixes, especially in the area of internationalization.
Naive uses of unicode have mostly been eliminated.</li>

behavior into binding classes corresponding to types from which other XML
types are extended or restricted. It also demonstrates how to introspect

<p>Primarily to fix a problem with chameleon schemas, but also a couple other
minor issues.</p>
<ul class="simple">
<li>References to QNames with absent namespaces in chameleon schema included
into schema with a target namespace could not be resolved. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/46/">SF ticket 46</a></li>

<h3>0.7.1 (23 Aug 2009, rev 1968)<a class="headerlink" href="#aug-2009-rev-1968" title="Permalink to this headline">¶</a></h3>
<p>None of the enhancements really got in, but lots of minor bug fixes.</p>
<ul class="simple">
<li>Restored the ability to dump copies of all schemas retrieved from a remote
location, so you can review them. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/28/">SF ticket 28</a></li>
<li>Fixed assorted problems with simple types constructed by list and union.
<a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/35/">SF ticket 35</a>, <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/40/">SF ticket 40</a></li>
<li>Provide link from content values to the element binding that was used to
store them. Useful for quickly identifying the owner element when
generating a valid child sequence for conversion to DOM. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/36/">SF ticket 36</a></li>
<li>Fix validation of attributes with union types. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/37/">SF ticket 37</a></li>
<li>Enumeration fixes: Only generate class-level constants for enumerations that
restrict a string representation (not double, float, etc). Verify
enumerations work correctly on list and union constructions. Duplicate the
class-level constants for enumerations that are defined in union member
types. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/38/">SF ticket 38</a></li>
<li>Provide a facility to simplify the automatic creation of an instance of the
appropriate type when storing values into an element. Makes life with
anonymous local elements a lot easier. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/39/">SF ticket 39</a></li>
<li>Enhance management of namespace prefixes by allowing a system-wide default
in BindingDOMSupport and by inferring the base name of the module as the
default prefix for namespaces defined in imported bindings. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/41/">SF ticket 41</a></li>
<li>Provided crude facility to bypass validation when generating and parsing
documents. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/44/">SF ticket 44</a></li>
<li>Re-arrange the help for pyxbgen’s arguments, and add a script to
automatically generate the Sphinx tables for it.</li>
<li>Support bundles of related schemas/namespaces, currently wssplat (for WS-*)
and opengis (Geographic Information Systems).</li>
<li>Got the user-level documentation back up to where it might actually help
somebody.</li>
</ul>

<h3>0.7.0 (03 Aug 2009, rev 1715)<a class="headerlink" href="#aug-2009-rev-1715" title="Permalink to this headline">¶</a></h3>
<p>This release is identical to 0.5.2 except that the binding interface has
completely changed. All examples have been updated; the documentation will be
updated later.</p>
<p>Note that the code in PyXB itself has not changed, and is not going to
change. However, properties produce an interface more natural to most Python
programs, so that has become the default style. See the –binding-style
parameter to pyxbgen if you want to change this.</p>
<ul class="simple">
<li>Change the method of accessing elements and attributes in bindings from
accessor methods (e.g., elt.attr(), elt.setAttr()) to properties (e.g.,
elt.attr). <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/18/">SF ticket 18</a></li>

<h3>0.5.2 (03 Aug 2009, rev 1706)<a class="headerlink" href="#aug-2009-rev-1706" title="Permalink to this headline">¶</a></h3>
<p>Mostly changes to namespaces in support of profiles and application schemas
which extend other namespaces with special components, or have their own
copies of somebody else’s schemas, etc. See the pyxbgen private/public
namespace switches.</p>
<ul class="simple">
<li>Presence of nested choice model groups caused the plurality calculations to
be wrong: some elements were dropped from the model, others were treated as
lists when only one instance would be permitted. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/34/">SF ticket 34</a></li>
<li>Content accessor would return wrong value for elements with simple type of
list variety. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/32/">SF ticket 32</a></li>
<li>Corrected handling of attributes when deriving complex types by
restriction. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/27/">SF ticket 27</a></li>
<li>Added a source module for XML namespace
(<a class="reference external" href="http://www.w3.org/XML/1998/namespace">http://www.w3.org/XML/1998/namespace</a>) with bindings linked to the built-in
component model. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/23/">SF ticket 23</a></li>
<li>Fix inadequacies in namespace archive management. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/22/">SF ticket 22</a></li>
</ul>
<p>This is expected to be the last release in 0.5.x. 0.7.0 should follow soon
thereafter, and only contain the change of default binding style from accessor
to property. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/18/">SF ticket 18</a></p>

<h3>0.5.1 (16 Jul 2009, rev 1502)<a class="headerlink" href="#jul-2009-rev-1502" title="Permalink to this headline">¶</a></h3>
<p>Fixed various problems with OpenGIS schemas, specifically dependency loops
induced by attempting to keep binding components within modules identified by
the schema they came from, and loss of bindings for one namespace due to its
being overwritten by those for another.</p>
<ul class="simple">
<li>The presence of a wildcard in a sequence or choice model group caused other
elements to be lost in the binding. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/29/">SF ticket 29</a></li>
<li>Rework content verification to operate on binding instances rather than DOM
nodes. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/24/">SF ticket 24</a></li>
<li>Use <cite>value()</cite> to extract the value of a complex type with simple content;
the <cite>content()</cite> method works only with element and mixed content.
<a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/21/">SF ticket 21</a></li>
<li>Add support to specify prefix to be used in QNames when generating DOM
documents from binding instances. Provide facility to re-use the
BindingDOMSupport instance for multiple conversions. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/15/">SF ticket 15</a></li>
<li>Tightened requirements on content type matching: no more will strings and
numbers automatically be converted to match the content model (probably for
a branch you didn’t intend). <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/14/">SF ticket 14</a></li>
<li>Fix problems overwriting binding modules with data from a different set of
namespaces. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/31/">SF ticket 31</a>.</li>
<li>Eliminated the schema group modules: too hard to avoid dependency loops.
Now all components are written into a single module, which is a namespace
group module if the components cross namespaces. A namespace-specific
module still exists, and imports only the relevant components from the group
module.</li>

<h3>0.5.0 (07 Jul 2009, rev 1446)<a class="headerlink" href="#jul-2009-rev-1446" title="Permalink to this headline">¶</a></h3>
<p>Ability to parse many of the OpenGIS schemas (gml, iso19139, citygml, ogc,
ogckml22, om, ows, sensorML, sos, swe, tml, ...).</p>
<ul class="simple">
<li>Completely rework include and import directives to correctly handle relative

the bindings). <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/10/">SF ticket 10</a></li>
<li>Complete missing implementations in complex types with simple content.
<a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/6/">SF ticket 6</a></li>
<li>Create new code generation model which supports inter-namespace and
inter-schema dependency cycles. Namespace archives can now holds all
namespaces that depend on each other.</li>
<li>Other miscellaneous. <a class="reference external" href="https://sourceforge.net/p/pyxb/tickets/11/">SF ticket 11</a></li>

</ul>
<p>Beware:</p>
<ul class="simple">
<li>Most of the classes in the new code generation model are undocumented.</li>
<li>The interface to <cite>pyxbgen</cite> has changed completely. Look at
