- By default, injected tokens are given an extended lifetime so they remain valid even after a new refreshed token is provided. The metric `serviceaccount_stale_tokens_total` can be used to monitor for workloads that are depending on the extended lifetime and are continuing to use tokens even after a refreshed token is provided to the container. If that metric indicates no existing workloads are depending on extended lifetimes, injected token lifetime can be shortened to 1 hour by starting...

- Fixes the `should support building a client with a CSR` E2E test to work with clusters configured with short certificate lifetimes ([#105396](https://github.com/kubernetes/kubernetes/pull/105396), [@liggitt](https://github.com/liggitt))

- Only extend token lifetimes when `--service-account-extend-token-expiration` is true and the requested token audiences are empty or exactly match all values for `--api-audiences`. ([#105954](https://github.com/kubernetes/kubernetes/pull/105954), [@jyotimahapatra](https://g...
