2. Update all dependencies to the latest versions.
3. Add support for downscoped tokens in AccessTokenProvider.
4. Implement FileSystem.openFile to take advantage of the FileStatus if
   passed.
5. Remove an obsolete AuthorizationHandler and related properties:

   fs.gs.authorization.handler.impl
   fs.gs.authorization.handler.properties.<AUTHORIZATION_HANDLER_PROPERTY>
   

6. Remove support for Apache HTTP transport and related property:

   fs.gs.http.transport.type
   

7. Support GCS fine-grained action in AuthorizationHandlers.
8. Decrease log level for hflush rate limit log message.
9. Remove Cooperative Locking support for directory operations and related
   properties:

   fs.gs.cooperative.locking.enable
   fs.gs.cooperative.locking.expiration.timeout.ms
   fs.gs.cooperative.locking.max.concurrent.operations
   

10. Migrate authentication to com.google.auth.Credentials and remove obsolete
    properties:

    enum property, instead of relying on inference of the authentication type
    based on the set configuration properties, and remove obsolete properties:

    fs.gs.auth.null.enable
    fs.gs.auth.service.account.enable
    

12. Add support for a new USER_CREDENTIALS authentication type that retrieves
    a refresh token using the authorisation code grant flow configured via the
    following properties:

    new sockets returned from the custom SSLSocketFactory. This guarantees the
    timeout is enforced during TLS handshakes when using Conscrypt as the
    security provider.
16. The Google Cloud Storage Connector now can be used as a
    Hadoop Credential Provider.
17. Added dependency on the Cloud Storage Client Library
    (google-cloud-storage).

    properties:

    fs.gs.inputstream.inplace.seek.limit
    fs.gs.inputstream.min.range.request.size

    fs.gs.rewrite.max.chunk.size
    

21. Remove .ms suffix from names and add support for time suffixes (ms, s,
    m, etc) in values of time-related properties:

    fs.gs.http.connect-timeout
    fs.gs.http.read-timeout
    fs.gs.max.wait.for.empty.object.creation
    fs.gs.outputstream.sync.min.interval
    fs.gs.performance.cache.max.entry.age
    

22. Change default values of properties:

    fs.gs.http.connect-timeout (default: 20s -> 5s)

    fs.gs.outputstream.upload.chunk.size (default: 64m -> 24m)
    

23. Upgrade Hadoop to 3.3.5.
24. Upgrade java-storage to 2.25.0
25. Add support for WORKLOAD_IDENTITY_FEDERATION_CREDENTIAL_CONFIG_FILE authentication type that retrieves a refresh token using workload identity federation configuraiton defined in: fs.gs.auth.workload.identity.federation.credential.config.file
