• Provides vector methods for compare (提供比较的向量方法): GreaterThan_Unsigned.
• Provides extension method for vectors (提供向量的扩展方法): AsSigned, AsUnsigned.
• VectorSameWExtensions add As method. Vector<T> add As Extension Methods (Vector<T> 增加 As 扩展方法).
• The IsHardwareAccelerated property has been added to the Vectors(/Vector128s/Vector256s/Vector512s) classes (Vectors(/Vector128s/Vector256s/Vector512s) 类增加了 IsHardwareAccelerated 属性).
• Added 128-bit integer type - ExInt128/ExUInt128 (增加了128位整数类型 - ExInt128/ExUInt128).
• (Experimental) Experimentally added the ExType(Extended type) mechanism to enable vector types to support 128-bit integers(ExInt128/ExUInt128). However, it is found that some functions do not work properly under some .NET versions. Therefore, it is recommended to prioritize using functions with the suffix "_Bit128" instead of ExType (实验性的增加了 ExType(扩展类型) 机制, 使向量类型能支持128位整数(ExInt128/ExUInt128). 但发现某些.NET版本下，个别函数的工作不正常. 故建议优先使用“_Bit128”后缀的函数, 而不是 ExType).
• The MathBitOperations class has been added. It provides these functions (增加了 MathBitOperations 类. 它提供了这些函数): Crc32C, IsPow2, LeadingZeroCount, Log2, PopCount, RoundUpToPowerOf2, RotateLeft, RotateRight, TrailingZeroCount.

• The UnsafeUtil class add methods (UnsafeUtil类增加了方法): GetArrayDataReference, Dec, Inc, PreDec, PreInc, PostDec, PostDecExcept, PostDecExceptZero, PostInc, PostIncExcept, PostIncExceptZero .
• Optimize type conversion for vector generic types by replacing (object) with the As method (优化向量泛型类型的类型转换, 用 As 方法取代 (object)).
• Optimize the combining of two vectors, using WithUpper instead of Create (优化两个向量的组合, 用 WithUpper 代替 Create). e,g, Narrow and more.
• Optimized hardware acceleration of YBitToByte, YBitToInt16, YBitToInt32, YBitToInt64 methods on all architecture. It no longer uses OnesComplement (优化YBitToByte, YBitToInt16, YBitToInt32, YBitToInt64方法在所有架构的硬件加速. 它不再使用 OnesComplement).
