Release 4.0.1

None

#1664 - Added support for the OptionalFeatureDeployment top-level folder.
#1665, #1667 - Formalized support for both the replicated config/wlsdeploy/custom/ and non-replicated wlsdeploy/custom locations. Added support in the Archive Helper Tool and tweaked the validation message to only notify the user if they are only using the non-replicated location.
#1669 - Enhanced the WLS Policy support to allow users to modify built-in policies.
#1674 - Added 12.2.1.4 and 14.1.1 April 2024 PSU support.

#1666 - Fixed a bug with extracting the WebLogic Remote Console extension that caused an error if the archive file includes a directory entry.
#1670 - Worked around a Jython 2.2.1 bug with posixpath.isfile() where it was returning False when the answer should have been True.
#1672 - Added None checks around plan file name calculations.

SSH support requires a reasonably recent version of Bouncy Castle. WDT picks up Bouncy Castle from WLST so, for example, the 12.2.1.4.0 GA release fails with the following error, as mentioned at https://github.com/hierynomus/sshj/issues/895 . Applying a recent PSU should resolve the issue for 12.2.1.4 and 14.1.1.

```
SSH support for the Update Domain Tool and Deploy Apps Tool does not work when using an archive file and the remote WebLogic Server is running on Windows using the optional, Windows-provided, OpenSSH component. This is due to an issue with the SSHJ library WDT is using. See https://github.com/hierynomus/sshj/issues/929 for more information.
