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

⚠️ Artifact update problem

Renovate failed to update artifacts related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: apps/point/core/Cargo.toml

Artifact update for base64 resolved to version 0.23.1, which is a pending version that has not yet passed the Minimum Release Age threshold.
Renovate was attempting to update to 0.23.0
This is (likely) not a bug in Renovate, but due to the way your project pins dependencies, _and_ how Renovate calls your package manager to update them.
Until Renovate supports specifying an exact update to your package manager (https://github.com/renovatebot/renovate/issues/41624), it is recommended to directly pin your dependencies (with `rangeStrategy=pin` for apps, or `rangeStrategy=widen` for libraries)
