[section:changes Changelog]
[h5 27.11.2014 - version 1.5]
Major release, featuring a lot of performance improvements and some new features.
* Specification changes:
# xml_document::load(const char_t*) was renamed to load_string; the old method is still available and will be deprecated in a future release
# xml_node::select_single_node was renamed to select_node; the old method is still available and will be deprecated in a future release.
* New features:
# Added xml_node::append_move and other functions for moving nodes within a document
# Added xpath_query::evaluate_node for evaluating queries with a single node as a result
* Performance improvements:
# Optimized XML parsing (10-40% faster with clang/gcc, up to 10% faster with MSVC)
# Optimized memory consumption when copying nodes in the same document (string contents is now shared)
# Optimized node copying (10% faster for cross-document copies, 3x faster for inter-document copies; also it now consumes a constant amount of stack space)
# Optimized node output (60% faster; also it now consumes a constant amount of stack space)
# Optimized XPath allocation (query evaluation now results in fewer temporary allocations)
# Optimized XPath sorting (node set sorting is 2-3x faster in some cases)
# Optimized XPath evaluation (XPathMark suite is 100x faster; some commonly used queries are 3-4x faster)
* Compatibility improvements:
# Fixed xml_node::offset_debug for corner cases
# Fixed undefined behavior while calling memcpy in some cases
# Fixed MSVC 2015 compilation warnings
# Fixed contrib/foreach.hpp for Boost 1.56.0
* Bug fixes
# Adjusted comment output to avoid malformed documents if the comment value contains "--"
# Fix XPath sorting for documents that were constructed using append_buffer
