// indeed that's what both the original RSA paper and the pre-FIPS // crypto/rsa implementation did. // // However, FIPS 186-5, A.1.1(3) requires computing it as e⁻¹ mod λ(N) // where λ(N) = lcm(p-1, q-1). // // This makes d smaller by 1.5 bits on average, which is irrelevant both // because we exclusively use the CRT for private operations and because // we use constant time windowed exponentiation. On the other hand, it // requires computing a GCD of two values that are not coprime, and then // a...

- Increased the coverage to 89.8%. ([#132607](https://github.com/kubernetes/kubernetes/pull/132607), [@ylink-lfs](https://github.com/ylink-lfs))

- The kubeconfig is now exposed in `the kube-scheduler` framework handle. Out-of-tree plugins can leverage that to build CRD informers easily. ([#100644](https://github.com/kubernetes/kubernetes/pull/100644), [@Huang-Wei](https://github.com/Huang-Wei))

### Other notable announcements

SIG Network is moving IPv6 to Beta in Kubernetes 1.18, after incrementing significantly the test coverage with new CI jobs.

#### Continuous Improvement
- Project sustainability is not just about features. Many SIGs have been working on  improving test coverage, ensuring the basics stay reliable, and stability of the core feature set and working on maturing existing features and cleaning up the backlog.
