Some examples of types of pull requests that are immediately helpful:

  - Fixing a bug without changing a public API.
  - Fixing or improving documentation.
  - Improvements to Maven configuration.

Guidelines for any code contributions:

  1. Any significant changes should be accompanied by tests. The project already
     has good test coverage, so look at some existing tests if you're unsure

**This release introduces new Kotlin-friendly APIs.** When we migrated OkHttp from Java to Kotlin in
OkHttp 4.0, we kept our Java-first APIs. With 5.0 we're continuing to support Java and adding
additional improvements for Kotlin users. In this alpha we're excited to skip-the-builder for
requests and remove a common source of non-null assertions (`!!`) on the response body.

## 📊 Performance Metrics

CoreLib 0.7.0 includes significant performance improvements through Java 21 optimizations:

- **5-15% faster** type conversions with pattern matching and switch expressions
- **Reduced memory allocation** in collection operations and bean copying

   * NOTE: We could get slightly better bases that would be treated as unsigned, but benchmarks
   * showed negligible performance improvements.

For the 1.8 release, SIG Node continued to focus
on a broad set of workload types, including hardware and performance
sensitive workloads such as data analytics and deep learning. The SIG also
delivered incremental improvements to node reliability.

It has been more than two years since the Linux kernel cgroups v2 API was declared stable. With some distributions now defaulting to this API, Kubernetes must support it to continue operating on those distributions. cgroups v2 offers several improvements over cgroups v1, for more information see the [cgroups v2](https://kubernetes.io/docs/concepts/architecture/cgroups/) documentation. While cgroups v1 will continue to be supported, this enhancement puts Kubernetes to be ready for eventual deprecation...
