This is part of the fix for 1215 bug #3496608 to randomize hash parameters. 1216 When compiled with XML_ATTR_INFO defined, adds new API member 1217 XML_GetAttributeInfo() that allows retrieving the byte 1218 offsets for attribute names and values (patch #3446384). 1219 Added CMake build system. 1220 See bug #2990652 and patch #3312568. 1221 Added run-benchmark target to Makefile.in - relies on testdata module 1222 present in the same relative location as in the repository. 1223 1224Release 2.0.1 Tue June 5 2007 1225 - Fixed bugs #1515266, #1515600: The character data handler's calling 1226 of XML_StopParser() was not handled properly; if the parser was 1227 stopped and the handler set to NULL, the parser would segfault. 1228 - Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed 1229 some character constants to be ASCII encoded. 1230 - Minor cleanups of the test harness. 1231 - Fixed xmlwf bug #1513566: "out of memory" error on file size zero. 1232 - Fixed outline.c bug #1543233: missing a final XML_ParserFree() call. 1233 - Fixes and improvements for Windows platform: 1234 bugs #1409451, #1476160, #1548182, #1602769, #1717322. 1235 - Build fixes for various platforms: 1236 HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180. 1237 All Unix: #1554618 (refreshed config.sub/config.guess). 1238 #1490371, #1613457: support both, DESTDIR and INSTALL_ROOT, 1239 without relying on GNU-Make specific features. 1240 #1647805: Patched configure.in to work better with Intel compiler. 1241 - Fixes to Makefile.in to have make check work correctly: 1242 bugs #1408143, #1535603, #1536684. 1243 - Added Open Watcom support: patch #1523242. 1244 1245Release 2.0.0 Wed Jan 11 2006 1246 - We no longer use the "check" library for C unit testing; we 1247 always use the (partial) internal implementation of the API. 1248 - Report XML_NS setting via XML_GetFeatureList(). 1249 - Fixed headers for use from C++. 1250 - XML_GetCurrentLineNumber() and XML_GetCurrentColumnNumber() 1251 now return unsigned integers. 1252 - Added XML_LARGE_SIZE switch to enable 64-bit integers for 1253 byte indexes and line/column numbers. 1254 - Updated to use libtool 1.5.22 (the most recent). 1255 - Added support for AmigaOS. 1256 - Some mostly minor bug fixes. SF issues include: #1006708, 1257 #1021776, #1023646, #1114960, #1156398, #1221160, #1271642. 1258 1259Release 1.95.8 Fri Jul 23 2004 1260 - Major new feature: suspend/resume. Handlers can now request 1261 that a parse be suspended for later resumption or aborted 1262 altogether. See "Temporarily Stopping Parsing" in the 1263 documentation for more details. 1264 - Some mostly minor bug fixes, but compilation should no 1265 longer generate warnings on most platforms. SF issues 1266 include: #827319, #840173, #846309, #888329, #896188, #923913, 1267 #928113, #961698, #985192. 1268 1269Release 1.95.7 Mon Oct 20 2003 1270 - Fixed enum XML_Status issue (reported on SourceForge many 1271 times), so compilers that are properly picky will be happy. 1272 - Introduced an XMLCALL macro to control the calling 1273 convention used by the Expat API; this macro should be used 1274 to annotate prototypes and definitions of callback 1275 implementations in code compiled with a calling convention 1276 other than the default convention for the host platform. 1277 - Improved ability to build without the configure-generated 1278 expat_config.h header. This is useful for applications 1279 which embed Expat rather than linking in the library. 1280 - Fixed a variety of bugs: see SF issues #458907, #609603, 1281 #676844, #679754, #692878, #692964, #695401, #699323, #699487, 1282 #820946. 1283 - Improved hash table lookups. 1284 - Added more regression tests and improved documentation. 1285 1286Release 1.95.6 Tue Jan 28 2003 1287 - Added XML_FreeContentModel(). 1288 - Added XML_MemMalloc(), XML_MemRealloc(), XML_MemFree(). 1289 - Fixed a variety of bugs: see SF issues #615606, #616863, 1290 #618199, #653180, #673791. 1291 - Enhanced the regression test suite. 1292 - Man page improvements: includes SF issue #632146. 1293 1294Release 1.95.5 Fri Sep 6 2002 1295 - Added XML_UseForeignDTD() for improved SAX2 support. 1296 - Added XML_GetFeatureList(). 1297 - Defined XML_Bool type and the values XML_TRUE and XML_FALSE. 1298 - Use an incomplete struct instead of a void* for the parser 1299 (may not retain). 1300 - Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected. 1301 - Finally fixed bug where default handler would report DTD 1302 events that were already handled by another handler. 1303 Initial patch contributed by Darryl Miles. 1304 - Removed unnecessary DllMain() function that caused static 1305 linking into a DLL to be difficult. 1306 - Added VC++ projects for building static libraries. 1307 - Reduced line-length for all source code and headers to be 1308 no longer than 80 characters, to help with AS/400 support. 1309 - Reduced memory copying during parsing (SF patch #600964). 1310 - Fixed a variety of bugs: see SF issues #580793, #434664, 1311 #483514, #580503, #581069, #584041, #584183, #584832, #585537, 1312 #596555, #596678, #598352, #598944, #599715, #600479, #600971. 1313 1314Release 1.95.4 Fri Jul 12 2002 1315 - Added support for VMS, contributed by Craig Berry. See 1316 vms/README.vms for more information. 1317 - Added Mac OS (classic) support, with a makefile for MPW, 1318 contributed by Thomas Wegner and Daryle Walker. 1319 - Added Borland C++ Builder 5 / BCC 5.5 support, contributed 1320 by Patrick McConnell (SF patch #538032). 1321 - Fixed a variety of bugs: see SF issues #441449, #563184, 1322 #564342, #566334, #566901, #569461, #570263, #575168, #579196. 1323 - Made skippedEntityHandler conform to SAX2 (see source comment) 1324 - Re-implemented WFC: Entity Declared from XML 1.0 spec and 1325 added a new error "entity declared in parameter entity": 1326 see SF bug report #569461 and SF patch #578161 1327 - Re-implemented section 5.1 from XML 1.0 spec: 1328 see SF bug report #570263 and SF patch #578161 1329 1330Release 1.95.3 Mon Jun 3 2002 1331 - Added a project to the MSVC workspace to create a wchar_t 1332 version of the library; the DLLs are named libexpatw.dll. 1333 - Changed the name of the Windows DLLs from expat.dll to 1334 libexpat.dll; this fixes SF bug #432456. 1335 - Added the XML_ParserReset() API function. 1336 - Fixed XML_SetReturnNSTriplet() to work for element names. 1337 - Made the XML_UNICODE builds usable (thanks, Karl!). 1338 - Allow xmlwf to read from standard input. 1339 - Install a man page for xmlwf on Unix systems. 1340 - Fixed many bugs; see SF bug reports #231864, #461380, #464837, 1341 #466885, #469226, #477667, #484419, #487840, #494749, #496505, 1342 #547350. Other bugs which we can't test as easily may also 1343 have been fixed, especially in the area of build support. 1344 1345Release 1.95.2 Fri Jul 27 2001 1346 - More changes to make MSVC happy with the build; add a single 1347 workspace to support both the library and xmlwf application. 1348 - Added a Windows installer for Windows users; includes 1349 xmlwf.exe. 1350 - Added compile-time constants that can be used to determine the 1351 Expat version 1352 - Removed a lot of GNU-specific dependencies to aide portability 1353 among the various Unix flavors. 1354 - Fix the UTF-8 BOM bug. 1355 - Cleaned up warning messages for several compilers. 1356 - Added the -Wall, -Wstrict-prototypes options for GCC. 1357 1358Release 1.95.1 Sun Oct 22 15:11:36 EDT 2000 1359 - Changes to get expat to build under Microsoft compiler 1360 - Removed all aborts and instead return an UNEXPECTED_STATE error. 1361 - Fixed a bug where a stray '%' in an entity value would cause an 1362 abort. 1363 - Defined XML_SetEndNamespaceDeclHandler.
