+- type: 'feature'
+  item: StaticString
+  diff: 社区增加新特性
+  influence: 增加StaticString库
+- type: 'feature'
+  item: Asio
+  diff: 社区增加新特性
+  influence: 增加ssl::host_name_verification，增加ssl::context构造函数，SSL依赖OpenSSL 1.0.2，ssl::context类会传播非EOF错误
+- type: 'feature'
+  item: Assert
+  diff: 社区增加新特性
+  influence: Assert库增加source_location
+- type: 'feature'
+  item: Atomic
+  diff: 社区增加新特性
+  influence: Atomic库增加atomic_ref、atomic_flag::test
+- type: 'feature'
+  item: Conversion
+  diff: 社区增加新特性
+  influence: Conversion库增加boost::polymorphic_downcast
+- type: 'feature'
+  item: data_time
+  diff: 社区增加新特性
+  influence: data_time支持constexpr
+- type: 'feature'
+  item: Geometry
+  diff: 社区增加新特性
+  influence: Geometry增加d3::point_xyz模型
+- type: 'feature'
+  item: GIL
+  diff: 社区增加新特性
+  influence: image类增加移动构造与移动赋值函数，any_image_view类增加size函数
+- type: 'feature'
+  item: Histogram
+  diff: 社区增加新特性
+  influence: reduce算法增加crop命令，reduce的slice命令支持category，增加count累加器，sum算法增加新参数
+- type: 'feature'
+  item: IO
+  diff: 社区增加新特性
+  influence: ostream_joiner实现基于分隔符的join
+- type: 'feature'
+  item: Log
+  diff: 社区增加新特性
+  influence: 默认sink在每个日志后自动flush
+- type: 'feature'
+  item: Math
+  diff: 社区增加新特性
+  influence: 增加Cubic Hermite Interpolation、Modified Akima Interpolation、PCHIP Interpolation、Quintic Hermite Interpolation，数值分布增加熵，增加面积计算的几种简单情况。
+- type: 'feature'
+  item: Mp11
+  diff: 社区增加新特性
+  influence: 增加mp_unique_if、mp_flatten、mp_rotate_left、mp_rotate_right、mp_compose、mp_power_set、mp_partial_sum、mp_iterate
+- type: 'feature'
+  item: Test
+  diff: 社区增加新特性
+  influence: BOOST_TEST增加tolerance indication, user message and collection comparison modifier
+- type: 'feature'
+  item: ThrowException
+  diff: 社区增加新特性
+  influence: throw_exception增加boost::source_location类型的重载
+- type: 'feature'
+  item: Variant2
+  diff: 社区增加新特性
+  influence: 支持std::hash与boost::hash
+- type: 'feature'
+  item: Atomic
+  diff: 社区删除特性
+  influence: boost/atomic/atomic.hpp不再包含boost/atomic/atomic_flag.hpp与boost/atomic/fences.hpp（涉及到的代码需改为包含boost/atomic.hpp），删除BOOST_ATOMIC_DETAIL_HIGHLIGHT_OP_AND_TEST宏（需使用*_and_test替代），atomic<T>现在考虑T的对齐要求
+- type: 'ABI'
+  item: data_time
+  diff: data_time全部内联，可以不链接库
+  influence: 无影响，社区保留了库以保持编译兼容。
+- type: 'ABI'
+  item: IO
+  diff: 调整ostream_string至IO库，并更名为ostream_put
+  influence: 用到此类的代码需要修改类名与库名
+- type: 'ABI'
+  item: Utility
+  diff: 调整ostream_string至IO库，并更名为ostream_put
+  influence: 用到此类的代码需要修改类名与库名
+remark: '功能增强;Utility库的ostream_string改为IO库的ostream_put;删除已过时的宏（需使用*_and_test替代）;修改头文件包含的内容（涉及到的代码需改为包含boost/atomic.hpp）;'
