Notable Changes:

• internal/sm2ec: adjust sub/add order in WW-MM reduction steps to make sure no unexpected carry /borrow.
• internal/sm2ec: use ADCX/ADOX for order mul/sqr WW-MM.
• sm4: optimize constant loading on arm64.
• zuc: optimize constant loading on arm64.
• upgrade third party dependencies.

Notable Changes:

• fix darwin/arm64 AES/PMULL features detect issue. darwin/arm64架构下，需要的CPU特性不好检测，golang.org/x/sys也没有处理这个问题，这里参考了Go语言internal/cpu中的处理方式。
• sm4: change to use pure go for single block encryption/decryption by default. 由于使用AES-NI实现的单block性能不佳（尤其是ARM64下），从这个版本开始单block处理改用纯Go语言查表方式实现，用户可以通过环境变量FORCE_SM4BLOCK_AESNI来强制使用AES-NI。

Notable Changes:

• internal/bigmod: sync sdk #200
• smx509: support openssl3 sm2 private key and public key whose alg OID is different with others

Notable Changes:

• smx509: can parse openssl v3.1.3 p8 sm2 private key #197 (解析openssl v3.1.3产生的SM2 P8私钥，其算法指定为SM2曲线OID)
• dep: upgrade dependencies (升级第三方依赖库)
• doc: added sm9 application guide (SM9应用指南)

Notable changes:

• sm2/ecdh: Fix and enhance sm2/ecdh generate private key checking #189. 修复私钥取值范围验证问题。
• sm2: Just compute the inverse of private key plus one per sm2.PrivateKey instance once #190. 每个私钥实例的私钥加一求逆运算仅计算一次，提升签名性能。
• sm2: Provide NewPrivateKey/NewPrivateKeyFromInt/NewPublicKey functions to avoid misapply #191. 提供通过给定值创建私钥、公钥的方法，方便用户使用。

Notable Changes:

• cipher: add HCTR/BC/OFBNLF operation modes (支持HCTR/BC/OFBNLF工作模式)
• sm2: fix enveloped key ASN.1 marshal/unmarshal issue #188 (修复SM2密钥对的保护数据格式的ASN.1处理错误)
• sm2: expose method CalculateSM2Hash function (提供SM2签名算法中计算哈希值的函数，可能有些KMS只接受HASH值)
• doc: enable github pages, added sm2/sm3/sm4 application guide (使用github pages功能提供了SM2/SM3/SM4应用指南)
• dep: upgrade dependencies (升级第三方依赖库)

Notable Changes:

• Upgrade dependencies (golang.org/x/sys v0.14.0 & golang.org/x/crypto v0.15.0), this requires Go v1.18+.
• Change interface{} to any, and remove "+build" build tag.
• 切片直接转数组指针.
• internal/subtle xor 简化代码，去除重复.
• arm64: Change VMOV to VDUP, duplicate value in general-purpose register to vector.
• smx509: optimize the performance of checkSignature.
• zuc: arm64 eia, uses VDUP/VMOVQ/VTBL to optimize the performance.

Requires Go v1.18+ since v0.23.0!

Notable Changes:

• internal/sm2ec: arm64, change global data loading method, change y2 loading method in p256PointAddAffineAsm.
• sm4: arm64, change global data loading method.
• zuc: arm64, change global data loading method.

Notable Changes:

• internal/sm2ec: uses NEON instructions for conditional move, select value from table and so on.
• sm9/bn256: uses NEON instructions for conditional move.

Will upgrade Go to v1.18 from v0.23.0.

Same as v0.21.5-beta.1
