   * The format is:
   *
   * ```
   * direction streamID length type flags
   * ```
   *
   * Where direction is `<<` for inbound and `>>` for outbound.

   * For example, the following would indicate a HEAD request sent from the client.
   * ```
   * `<< 0x0000000f    12 HEADERS       END_HEADERS|END_STREAM

- Fixed a concurrent map access in `TopologyCache`'s `HasPopulatedHints` method. ([#118189](https://github.com/kubernetes/kubernetes/pull/118189), [@Miciah](https://github.com/Miciah))
- Fixed a regression (`CLIENTSET_PKG: unbound variable`) when invoking deprecated `generate-groups.sh` script. ([#120877](https://github.com/kubernetes/kubernetes/pull/120877), [@soltysh](https://github.com/soltysh))
