68 Lisps using full 21 bit code points as characters are now fully
69 supported (including SBCL and Clozure CL) addition to the
70 existing support for 16 bit characters using UTF-16 (including
71 Allegro and LispWorks). The feature <tt>rune-is-utf-16</tt> is
72 now set on 16 bit Lisps.<br/><br/> Make sure to update and
73 recompile both cxml and closure-common when upgrading.
76 New sink slot omit-xml-declaration-p; functions cxml:unescaped
80 Fixed various DTD serialization bugs. Fixed xmls compatibility
81 bugs. Fixed variable names in with-source. Fixed

90 Runes have now been moved into
91 a <b>separate CVS module</b> unter the
92 name <b>closure-common</b>. Releases will be available
93 as <b>separate tarballs</b> in the download directory. Please
94 refer to the <a href="installation.html#download">
95 installation instructions</a> for details.

100 Moved runes into a separate project.
103 Incompatible SAX changes: Added new classes
104 sax:abstract-handler, sax:content-handler, sax:default-handler.
105 Implementations of SAX handlers should now subclass one of
109 fixed make-source :buffering nil, thanks to Magnus Henoch for
113 fixed time and space usage in cases where entity references
114 follow each other (thanks to Ivan Shvedunov for the report)
117 In the DOM builder, grow a buffer for string normalization
118 exponentially, fixing a long-standing speed issue.

123 <li>Various DTD serialization fixes</li>
124 <li>UTF-8 fix, thanks to Francis Leboutte</li>

127 <ul class="nomargin">
129 Fixed build on non-Unicode lisps. Fixed parsing on
130 non-Unicode lisps. Fixed Unicode detection on OpenMCL.
132 <li>New function <tt>cxml:parse</tt>.</li>
133 <li>Serialization no longer defaults to canonical form.</li>
134 <li>Fixed octet array argument to make-source.</li>
136 XMLS compatibility is not <i>bug-for-bug</i>-compatible with
137 XMLS any more. There is now a mode using pairs of local name
138 and namespace URI, and a second mode using qualified names
139 only. The old behaviour using pairs of prefix and local names
140 was removed. (Thanks to Douglas Crosher.)
143 SCL support (thanks to Douglas Crosher). Includes support for
144 implementations where URIs are valid namestrings, and a mode
145 where normal streams are used instead of xstreams and ystreams
146 (albeit both SCL-specific at this point).
148 <li>new convenience serialization function cxml:doctype. Various
149 DTD serialization fixes.</li>
151 <p class="nomargin"><tt>rel-2007-05-26</tt></p>

153 <li>cxml.asd has been split up into <tt>cxml.asd</tt> for the
154 XML parser and <tt>runes.asd</tt> for the runes package, in
155 preparation of a complete split of the two systems. Future CXML
156 releases will use separate tarballs for <tt>runes</tt>
157 and <tt>cxml</tt>.</li>
158 <li>xml:base support (SAX and Klacks only, not yet used in DOM).
159 See documentation <a href="sax.html#saxparser">here</a> and <a
160 href="klacks.html#locator">here</a>.</li>
161 <li>New class <tt>broadcast-handler</tt> as a generalization
162 of the older <tt>sax-proxy</tt>.</li>
163 <li>New class <tt>tapping-source</tt>, a klacks source that
164 relays events from an upstream klacks source unchanged, while also
165 emitting them as SAX events to a user-specified handler at the
167 <li>Changed attributes to carry an lname even when occurring
168 without a namespace. Added new functions attribute*,
169 unparse-attribute, and macro with-element*, with-namespace* to
170 the SAX generation wrapper API.</li>
171 <li>Klacks improvements: Incompatibly changed
172 klacks:find-element and find-event to consider the current event
173 as a result. Added klacks-error, klacks:expect, klacks:skip,
174 klacks:expecting-element. Fixed serialize-event to generate
175 start-prefix-mapping and end-prefix-mapping events. New function
176 map-current-namespace-declarations.</li>
