100
101Release 2.0.1 Tue June 5 2007
102        - Fixed bugs #1515266, #1515600: The character data handler's calling
103          of XML_StopParser() was not handled properly; if the parser was
104          stopped and the handler set to NULL, the parser would segfault.
105        - Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
106          some character constants to be ASCII encoded.
107        - Minor cleanups of the test harness.
108        - Fixed xmlwf bug #1513566: "out of memory" error on file size zero.
109        - Fixed outline.c bug #1543233: missing a final XML_ParserFree() call.
110        - Fixes and improvements for Windows platform:
111          bugs #1409451, #1476160, #1548182, #1602769, #1717322.
112        - Build fixes for various platforms:
113          HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180.
114          All Unix: #1554618 (refreshed config.sub/config.guess).
115                    #1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
116                    without relying on GNU-Make specific features.
117          #1647805: Patched configure.in to work better with Intel compiler.
118        - Fixes to Makefile.in to have make check work correctly:
119          bugs #1408143, #1535603, #1536684.
120        - Added Open Watcom support: patch #1523242.
121
122Release 2.0.0 Wed Jan 11 2006
123        - We no longer use the "check" library for C unit testing; we
124          always use the (partial) internal implementation of the API.
125        - Report XML_NS setting via XML_GetFeatureList().
126        - Fixed headers for use from C++.
127        - XML_GetCurrentLineNumber() and  XML_GetCurrentColumnNumber()
128          now return unsigned integers.
129        - Added XML_LARGE_SIZE switch to enable 64-bit integers for
130          byte indexes and line/column numbers.
131        - Updated to use libtool 1.5.22 (the most recent).
132        - Added support for AmigaOS.
133        - Some mostly minor bug fixes. SF issues include: #1006708,
134          #1021776, #1023646, #1114960, #1156398, #1221160, #1271642.
135
136Release 1.95.8 Fri Jul 23 2004
137        - Major new feature: suspend/resume.  Handlers can now request
138          that a parse be suspended for later resumption or aborted
139          altogether.  See "Temporarily Stopping Parsing" in the
140          documentation for more details.
141        - Some mostly minor bug fixes, but compilation should no
142          longer generate warnings on most platforms.  SF issues
143          include: #827319, #840173, #846309, #888329, #896188, #923913,
144          #928113, #961698, #985192.
145
146Release 1.95.7 Mon Oct 20 2003
147        - Fixed enum XML_Status issue (reported on SourceForge many
148          times), so compilers that are properly picky will be happy.
149        - Introduced an XMLCALL macro to control the calling
150          convention used by the Expat API; this macro should be used
151          to annotate prototypes and definitions of callback
152          implementations in code compiled with a calling convention
153          other than the default convention for the host platform.
154        - Improved ability to build without the configure-generated
155          expat_config.h header.  This is useful for applications
156          which embed Expat rather than linking in the library.
157        - Fixed a variety of bugs: see SF issues #458907, #609603,
158          #676844, #679754, #692878, #692964, #695401, #699323, #699487,
159          #820946.
160        - Improved hash table lookups.
161        - Added more regression tests and improved documentation.
162
163Release 1.95.6 Tue Jan 28 2003
164        - Added XML_FreeContentModel().
165        - Added XML_MemMalloc(), XML_MemRealloc(), XML_MemFree().
166        - Fixed a variety of bugs: see SF issues #615606, #616863,
167          #618199, #653180, #673791.
168        - Enhanced the regression test suite.
169        - Man page improvements: includes SF issue #632146.
170
171Release 1.95.5 Fri Sep 6 2002
172        - Added XML_UseForeignDTD() for improved SAX2 support.
173        - Added XML_GetFeatureList().
174        - Defined XML_Bool type and the values XML_TRUE and XML_FALSE.
175        - Use an incomplete struct instead of a void* for the parser
176          (may not retain).
177        - Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected.
178        - Finally fixed bug where default handler would report DTD
179          events that were already handled by another handler.
180          Initial patch contributed by Darryl Miles.
181        - Removed unnecessary DllMain() function that caused static
182          linking into a DLL to be difficult.
183        - Added VC++ projects for building static libraries.
184        - Reduced line-length for all source code and headers to be
185          no longer than 80 characters, to help with AS/400 support.
186        - Reduced memory copying during parsing (SF patch #600964).
187        - Fixed a variety of bugs: see SF issues #580793, #434664,
188          #483514, #580503, #581069, #584041, #584183, #584832, #585537,
189          #596555, #596678, #598352, #598944, #599715, #600479, #600971.
190
191Release 1.95.4 Fri Jul 12 2002
192        - Added support for VMS, contributed by Craig Berry.  See
193          vms/README.vms for more information.

195          contributed by Thomas Wegner and Daryle Walker.
196        - Added Borland C++ Builder 5 / BCC 5.5 support, contributed
197          by Patrick McConnell (SF patch #538032).

199          #564342, #566334, #566901, #569461, #570263, #575168, #579196.
200        - Made skippedEntityHandler conform to SAX2 (see source comment)
201        - Re-implemented WFC: Entity Declared from XML 1.0 spec and
202          added a new error "entity declared in parameter entity":
203          see SF bug report #569461 and SF patch #578161
204        - Re-implemented section 5.1 from XML 1.0 spec:
205          see SF bug report #570263 and SF patch #578161
206
207Release 1.95.3 Mon Jun 3 2002
208        - Added a project to the MSVC workspace to create a wchar_t
209          version of the library; the DLLs are named libexpatw.dll.
210        - Changed the name of the Windows DLLs from expat.dll to
211          libexpat.dll; this fixes SF bug #432456.

218          #466885, #469226, #477667, #484419, #487840, #494749, #496505,
219          #547350.  Other bugs which we can't test as easily may also
220          have been fixed, especially in the area of build support.
221
222Release 1.95.2 Fri Jul 27 2001
223        - More changes to make MSVC happy with the build; add a single
224          workspace to support both the library and xmlwf application.
225        - Added a Windows installer for Windows users; includes
226          xmlwf.exe.

236        - Changes to get expat to build under Microsoft compiler
237        - Removed all aborts and instead return an UNEXPECTED_STATE error.
238        - Fixed a bug where a stray '%' in an entity value would cause an
239          abort.
240        - Defined XML_SetEndNamespaceDeclHandler. Thanks to Darryl Miles for
241          finding this oversight.
242        - Changed default patterns in lib/Makefile.in to fit non-GNU makes
243          Thanks to robin@unrated.net for reporting and providing an
244          account to test on.
245        - The reference had the wrong label for XML_SetStartNamespaceDecl.
246          Reported by an anonymous user.
247
248Release 1.95.0 Fri Sep 29 2000
249        - XML_ParserCreate_MM
250                Allows you to set a memory management suite to replace the
251                standard malloc,realloc, and free.
252        - XML_SetReturnNSTriplet
253                If you turn this feature on when namespace processing is in
254                effect, then qualified, prefixed element and attribute names
255                are returned as "uri|name|prefix" where '|' is whatever
256                separator character is used in namespace processing.
257        - Merged in features from perl-expat
258                o XML_SetElementDeclHandler
259                o XML_SetAttlistDeclHandler
260                o XML_SetXmlDeclHandler
261                o XML_SetEntityDeclHandler
262                o StartDoctypeDeclHandler takes 3 additional parameters:
263                        sysid, pubid, has_internal_subset
264                o Many paired handler setters (like XML_SetElementHandler)
265                  now have corresponding individual handler setters
266                o XML_GetInputContext for getting the input context of
267                  the current parse position.
268        - Added reference material
269        - Packaged into a distribution that builds a sharable library
270
