### Major Themes

  * <strong>Significant scale improvements</strong>. Increased cluster scale by 400% to 1000 nodes with 30,000 pods per cluster.
Kubelet supports 100 pods per node with 4x reduced system overhead.

 *
 * <p>This class is intended as a replacement for {@link ReentrantLock}. Code using {@code Monitor}
 * is less error-prone and more readable than code using {@code ReentrantLock}, without significant
 * performance loss. {@code Monitor} even has the potential for performance gain by optimizing the
 * evaluation and signaling of conditions. Signaling is entirely <a

// Rejects strings with following characters.

## Código Asíncrono { #asynchronous-code }

El código asíncrono simplemente significa que el lenguaje 💬 tiene una forma de decirle a la computadora / programa 🤖 que en algún momento del código, tendrá que esperar que *otra cosa* termine en otro lugar. Digamos que esa *otra cosa* se llama "archivo-lento" 📝.

   *
   * <p>For the case of {@link RoundingMode#HALF_EVEN}, this implementation uses the IEEE 754
   * default rounding mode: if the two nearest representable values are equally near, the one with
   * the least significant bit zero is chosen. (In such cases, both of the nearest representable
   * values are even integers; this method returns the one that is a multiple of a greater power of
   * two.)

- Kube-proxy iptables probabilities are now more granular and will result in better distribution beyond 319 endpoints. ([#83599](https://github.com/kubernetes/kubernetes/pull/83599), [@robscott](https://github.com/robscott))
- Significant kube-proxy performance improvements for non UDP ports. ([#83208](https://github.com/kubernetes/kubernetes/pull/83208), [@robscott](https://github.com/robscott))
