Release Notes

marshallpierce/rust-base64 (base64)

v0.23.0

Compare Source

• Added more consts for preconfigured configs and engines
• Make DecodeError::InvalidLastSymbol more clear by including the decoded value
• Added SIMD-accelerated engines behind the default-on simd-unsafe feature: Simd picks the best
  instruction set at runtime (AVX2 on x86_64, NEON on aarch64) and falls back to the scalar
  GeneralPurpose engine, while Avx2 and Neon target one instruction set with no runtime
  detection and work in no_std. The engines support the standard and URL-safe alphabets.
• Update MSRV to 1.71.0
• Add support for custom padding symbols
