1.07.2010 - v0.9 Major release, featuring extended and improved Unicode support, miscellaneous performance improvements, bug fixes and more. Major Unicode improvements: Introduced encoding support (automatic/manual encoding detection on load, manual encoding selection on save, conversion from/to UTF8, UTF16 LE/BE, UTF32 LE/BE) Introduced wchar_t mode (you can set PUGIXML_WCHAR_MODE define to switch pugixml internal encoding from UTF8 to wchar_t; all functions are switched to their Unicode variants) Load/save functions now support wide streams Bug fixes: Fixed document corruption on failed parsing bug XPath string <-> number conversion improvements (increased precision, fixed crash for huge numbers) Improved DOCTYPE parsing: now parser recognizes all well-formed DOCTYPE declarations Fixed xml_attribute::as_uint() for large numbers (i.e. 2^32-1) Specification changes: parse() API changed to load_buffer/load_buffer_inplace/load_buffer_inplace_own; load_buffer APIs do not require zero-terminated strings. Renamed as_utf16 to as_wide Changed xml_node::offset_debug return type and xml_parse_result::offset type to ptrdiff_t Nodes/attributes with empty names are now printed as :anonymous Performance improvements: Optimized document parsing and saving Changed internal memory management: internal allocator is used for both metadata and name/value data; allocated pages are deleted if all allocations from them are deleted Optimized memory consumption: sizeof(xml_node_struct) reduced from 40 bytes to 32 bytes on x86 Optimized debug mode parsing/saving by order of magnitude Miscellaneous: All STL includes except in pugixml.hpp are replaced with forward declarations Compatibility: parse() and as_utf16 are left for compatibility (these functions are deprecated and will be removed in pugixml-1.0) Wildcard functions, document_order/precompute_document_order functions, format_write_bom_utf8 and parse_wnorm_attribute flags are deprecated and will be removed in version 1.0 8.11.2009 - v0.5 Major bugfix release. Changes: XPath bugfixes: Fixed translate(), lang() and concat() functions (infinite loops/crashes) Fixed compilation of queries with empty literal strings ("") Fixed axis tests: they never add empty nodes/attributes to the resulting node set now Fixed string-value evaluation for node-set (the result excluded some text descendants) Fixed self:: axis (it behaved like ancestor-or-self::) Fixed following:: and preceding:: axes (they included descendent and ancestor nodes, respectively) Minor fix for namespace-uri() function (namespace declaration scope includes the parent element of namespace declaration attribute) Some incorrect queries are no longer parsed now (i.e. foo: *) Fixed text()/etc. node test parsing bug (i.e. foo[text()] failed to compile) Fixed root step (/) - it now selects empty node set if query is evaluated on empty node Fixed string to number conversion ("123 " converted to NaN, "123 .456" converted to 123.456 - now the results are 123 and NaN, respectively) Node set copying now preserves sorted type; leads to better performance on some queries Miscellaneous bugfixes: Fixed xml_node::offset_debug for PI nodes Added empty attribute checks to xml_node::remove_attribute Fixed node_pi and node_declaration copying Const-correctness fixes Specification changes: xpath_node::select_nodes() and related functions now throw exception if expression return type is not node set (instead of assertion) xml_node::traverse() now sets depth to -1 for both begin() and end() callbacks (was 0 at begin() and -1 at end()) In case of non-raw node printing a newline is output after PCDATA inside nodes if the PCDATA has siblings UTF8 -> wchar_t conversion now considers 5-byte UTF8-like sequences as invalid New features: Added xpath_node_set::operator[] for index-based iteration Added xpath_query::return_type() Added getter accessors for memory-management functions 17.09.2009 - v0.42 Maintenance release. Changes: Fixed deallocation in case of custom allocation functions or if delete[] / free are incompatible XPath parser fixed for incorrect queries (i.e. incorrect XPath queries should now always fail to compile) Added PUGIXML_API/PUGIXML_CLASS/PUGIXML_FUNCTION configuration macros to control class/function attributes Const-correctness fixes for find_child_by_attribute Improved compatibility (miscellaneous warning fixes, fixed cstring include dependency for GCC) Fixed iterator begin/end and print function to work correctly for empty nodes Added xml_attribute::set_value overloads for different types 8.02.2009 - v0.41 Maintenance release. Changes: Fixed bug with node printing (occasionally some content was not written to output stream) 18.01.2009 - v0.4 Changes: Bugs: Documentation fix in samples for parse() with manual lifetime control Fixed document order sorting in XPath (it caused wrong order of nodes after xpath_node_set::sort and wrong results of some XPath queries) Node printing changes: Single quotes are no longer escaped when printing nodes Symbols in second half of ASCII table are no longer escaped when printing nodes; because of this, format_utf8 flag is deleted as it's no longer needed and format_write_bom is renamed to format_write_bom_utf8. Reworked node printing - now it works via xml_writer interface; implementations for FILE* and std::ostream are available. As a side-effect, xml_document::save_file now works without STL. New features: Added unsigned integer support for attributes (xml_attribute::as_uint, xml_attribute::operator=) Now document declaration () is parsed as node with type node_declaration when parse_declaration flag is specified (access to encoding/version is performed as if they were attributes, i.e. doc.child("xml").attribute("version").as_float()); corresponding flags for node printing were also added Added support for custom memory management (see set_memory_management_functions for details) Implemented node/attribute copying (see xml_node::insert_copy_* and xml_node::append_copy for details) Added find_child_by_attribute and find_child_by_attribute_w to simplify parsing code in some cases (i.e. COLLADA files) Added file offset information querying for debugging purposes (now you're able to determine exact location of any xml_node in parsed file, see xml_node::offset_debug for details) Improved error handling for parsing - now load(), load_file() and parse() return xml_parse_result, which contains error code and last parsed offset; this does not break old interface as xml_parse_result can be implicitly casted to bool. 31.10.2007 - v0.34 Maintenance release. Changes: Improved compatibility (supported Digital Mars C++, MSVC 6, CodeWarrior 8, PGI C++, Comeau, supported PS3 and XBox360) Fixed bug with loading from text-mode iostreams Fixed leak when transfer_ownership is true and parsing is failing Fixed bug in saving (\r and \n are now escaped in attribute values) PUGIXML_NO_EXCEPTION flag for platforms without exception handling Renamed free() to destroy() - some macro conflicts were reported 21.02.2007 - v0.3 Refactored, reworked and improved version. Changes: Interface: Added XPath Added tree modification functions Added no STL compilation mode Added saving document to file Refactored parsing flags Removed xml_parser class in favor of xml_document Added transfer ownership parsing mode Modified the way xml_tree_walker works Iterators are now non-constant Implementation: Support of several compilers and platforms Refactored and sped up parsing core Improved standard compliancy Added XPath implementation Fixed several bugs 6.11.2006 - v0.2 First public release. Changes: Introduced child_value(name) and child_value_w(name) Fixed child_value() (for empty nodes) Fixed xml_parser_impl warning at W4 parse_eol_pcdata and parse_eol_attribute flags + parse_minimal optimizations Optimizations of strconv_t 15.07.2006 - v0.1 First private release for testing purposes
