0.102.0

Headlines

• More powerful certificate revocation list (CRL) support. There is now an API for explicitly configuring whether CRLs are mandatory or optional, and which parts of the certificate chain they apply to.
• Extensible and observable path building. This crate now returns an example of a found certificate path, and optionally allows callers to reject valid paths to continue the search.
• Improving API stability. This crate now uses types from rustls-pki-types; we expect this to reduce the number of breaking changes in rustls ecosystem.
• Pluggable crypto providers. This crate can now depend on signature verification algorithms provided externally. ring is now an optional (but default) dependency, and aws-lc-rs is a new optional dependency.
