- Fix: set nil cache entry based on old cache ([#87591](https://github.com/kubernetes/kubernetes/pull/87591), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

- Fix: do not delete the lb that does not exist (#105777, @nilo19) [SIG Cloud Provider]
- Fix: ignore not a VMSS error for VMAS nodes in EnsureBackendPoolDeleted. (#105185, @ialidzhikov) [SIG Cloud Provider]
- Fix: leave the probe path empty for TCP probes (#105253, @nilo19) [SIG Cloud Provider]

Coinciding with this change, new releases of
[TensorFlow's Docker images](https://hub.docker.com/r/tensorflow/tensorflow/)
provide Python 3 exclusively. Because all images now use Python 3, Docker tags
containing `-py3` will no longer be provided and existing `-py3` tags like
`latest-py3` will not be updated.

        FessSecurityResourceProvider provider1 = new FessSecurityResourceProvider(inver1, oneWay1);
        FessSecurityResourceProvider provider2 = new FessSecurityResourceProvider(inver2, oneWay2);

        assertEquals(inver1, provider1.providePrimaryInvertibleCryptographer());
        assertEquals(inver2, provider2.providePrimaryInvertibleCryptographer());

        // Verify it's the same instance for all provider instances
        FessUserTimeZoneProcessProvider provider1 = new FessUserTimeZoneProcessProvider();
        FessUserTimeZoneProcessProvider provider2 = new FessUserTimeZoneProcessProvider();

        TimeZone tz1 = provider1.getRequestedTimeZone(requestManager);
        TimeZone tz2 = provider2.getRequestedTimeZone(requestManager);

Integrating other authentication/authorization providers like Google, Facebook, X (Twitter), GitHub, etc. is also possible and relatively easy.

The most complex problem is building an authentication/authorization provider like those, but **FastAPI** gives you the tools to do it easily, while doing the heavy lifting for you.
