Breaking changes

This release includes changes to the networking stack used by uv. While we think that breakage will be rare, it is possible that these changes will result in the rejection of certificates previously trusted by uv so we have marked the change as breaking out of an abundance of caution.

The changes are largely driven by the upgrade of reqwest, which powers uv's HTTP clients, to v0.13 which included some breaking changes to TLS certificate verification.

The following changes are included:

• rustls-platform-verifier is used instead of rustls-native-certs and webpki for certificate verification

  This change should have no effect unless you are using the native-tls option to enable reading system certificates.

  rustls-platform-verifier delegates to the system for certificate validation (e.g., Security.framework on macOS) instead of eagerly loading certificates from the system and verifying them via webpki. The effects of this change will vary based on the operating system. In general, uv's certificate validation should now be more consistent with browsers and other native applications. However, this is the most likely cause of breaking changes in this release. Some previously failing certificate chains may succeed, and some previously accepted certificate chains may fail. In either case, we expect the validation to be more correct and welcome reports of regressions.

  In particular, because more responsibility for validating the certificate is transferred to your system's security library, some features like CA constraints or revocation of certificates via OCSP and CRLs may now be used.

  This change should improve performance when using system certificate on macOS, as uv no longer needs to load all certificates from the keychain at startup.

• aws-lc is used instead of ring for a cryptography backend

  There should not be breaking changes from this change. We expect this to expand support for certificate signature algorithms.

• --native-tls is deprecated in favor of a new --system-certs flag

  The --native-tls flag is still usable and has identical behavior to --system-certs.

  This change was made to reduce confusion about the TLS implementation uv uses. uv always uses rustls not native-tls.

• Building uv on x86-64 and i686 Windows requires NASM

  NASM is required by aws-lc. If not found on the system, a prebuilt blob provided by aws-lc-sys will be used.

  If you are not building uv from source, this change has no effect.

  See the CONTRIBUTING guide for details.

• Empty SSL_CERT_FILE values are ignored (for consistency with SSL_CERT_DIR)

See #​18550 for details.
