| <p>Expat is an XML parser library written in C. It is a |
| stream-oriented parser in which an application registers handlers for |
| things the parser might find in the XML document (like start tags). |
| An <a href="http://www.xml.com/pub/1999/09/expat/index.html" |
| >introductory article</a> on using Expat is available on |
| <a href="http://www.xml.com/">xml.com</a>.</p> |

| <p>This project aims to maintain Expat for both current and future |
| users while improving the API to allow more reliable and robust access |
| from "scripting" languages such as Python and Perl. We invite the |
| community to participate on the mailing lists to help shape the future |
| of Expat.</p> |

| <h3 id="news">News</h3> |
| |
| <dl> |
| <dt><em>23 July 2004</em>, |
| Expat 1.95.8 released. |
| </dt> |
| <dd> |
| <p>The release schedule described in the previous news item didn't |
| work out. As a compensation, we've fixed a number of the |
| nuissance warnings generated on many platforms, and added a nice |
| new suspend/resume feature to the parser.</p> |
| <ul> |
| <li> Major new feature: suspend/resume. Handlers can now request |
| that a parse be suspended for later resumption or aborted |
| altogether. See "Temporarily Stopping Parsing" in the |
| documentation for more details. </li> |
| <li> Some mostly minor bug fixes, but compilation should no |
| longer generate warnings on most platforms. SF issues |
| include: 827319, 840173, 846309, 888329, 896188, 923913, |
| 928113, 961698, 985192.</li> |
| </ul> |
| </dd> |
| <dt><em>20 October 2003</em>, |
| Expat 1.95.7 released. |
| </dt> |
| <dd> |
| <ul> |
| <li> Fixed <code>enum XML_Status</code> issue (reported on |
| SourceForge many times), so compilers that are properly |
| picky will be happy. </li> |
| <li> Introduced an <code>XMLCALL</code> macro to control the |
| calling convention used by the Expat API; this macro should |
| be used to annotate prototypes and definitions of callback |
| implementations in code compiled with a calling convention |
| other than the default convention for the host |
| platform. </li> |
| <li> Improved ability to build without the |
| <b>configure</b>-generated <span |
| class="filename">expat_config.h</span> header. This is |
| useful for applications which embed Expat rather than |
| linking in the library. </li> |
| <li> Fixed a variety of bugs: see SF issues 458907, 609603, |
| 676844, 679754, 692878, 692964, 695401, 699323, 699487, |
| 820946. </li> |
| <li> Improved hash table lookups. </li> |
| <li> Added more regression tests and improved documentation. </li> |
| </ul> |
| <p>Our plan is to wait for a short while and re-release this |
| version as the long-awaited Expat 2.0 if no major problems are |
| identified. If significant problems are found, additional |
| iterative releases will be made as fixes are made.</p> |
| </dd> |
| <dt><em>15 October 2003</em>, |
| Upcoming release. |

| <dd> |
| <p>We're working on getting the long-delayed Expat 1.95.7 out the |
| door. A snapshot of the current source code is available as <a |
| href= "expat-2003-10-15.tar.gz" >expat-2003-10-15.tar.gz</a>; |
| please give this a try on your platform and report how it works |
| for you to the <a href= |
| "http://mail.libexpat.org/mailman/listinfo/expat-discuss" |
| >expat-discuss</a> mailing list. Our goals for this release are |
| portability and stability. |
| </p> |
| </dd> |
| <dt><em>28 January 2003</em>, |
| Expat 1.95.6 released. |
| </dt> |
| <dd> |
| <ul> |
| <li> Added <code>XML_FreeContentModel()</code>. </li> |
| <li> Added <code>XML_MemMalloc()</code>, |
| <code>XML_MemRealloc()</code>, |
| <code>XML_MemFree()</code>. </li> |
| <li> Fixed a variety of bugs: see SF issues 615606, 616863, |
| 618199, 653180, 673791. </li> |
| <li> Enhanced the regression test suite. </li> |
| <li> Man page improvements: includes SF issue 632146. </li> |
| </ul> |
| <p /> |
| </dd> |
| <dt><em>6 September 2002</em>, |
| Expat 1.95.5 released. |
| </dt> |
| <dd> |
| <ul> |
| <li> Added <code>XML_UseForeignDTD()</code> for improved SAX2 |
| support. </li> |
| <li> Added <code>XML_GetFeatureList()</code>. </li> |
| <li> Defined <code>XML_Bool</code> type and the values |
| <code>XML_TRUE</code> and <code>XML_FALSE</code>. </li> |
| <li> Use an incomplete struct instead of a <code>void*</code> |
| for the parser. </li> |
| <li> Fixed UTF-8 decoding bug that caused legal UTF-8 to be |
| rejected. </li> |
| <li> Finally fixed bug where default handler would report DTD |
| events that were already handled by another handler. |
| Initial patch contributed by Darryl Miles. </li> |
| <li> Removed unnecessary <code>DllMain()</code> function that |
| caused static linking into a DLL to be difficult. </li> |
| <li> Added VC++ projects for building static libraries. </li> |
| <li> Reduced line-length for all source code and headers to be |
| no longer than 80 characters, to help with AS/400 |
| support. </li> |
| <li> Reduced memory copying during parsing (SF patch #600964). </li> |
| <li> Fixed a variety of bugs: see SF issues 580793, 434664, |
| 483514, 580503, 581069, 584041, 584183, 584832, 585537, |
