Release 4.1.1

None

#1685 - Filtered out the default OptionalFeatures folders when they have no attributes so that they do not show up in the online discovered model.

#1677 - Fixed a bug where creating a user with extra attributes would result in invalid LDIFT entries.
#1678 - Fixed a bug that was causing errors when deploying a new application and the server required a restart.
#1679 - Fixed a bug where the SSHJ libraries (that only work with JDK 8 and later) were causing the tools to fail when running with JDK 7.
#1680 - Fixed the DataSourceLogFile and WebServerLog folders default value for the DateFormatPattern attribute for WLS versions prior to 12.2.1 so that they no longer show up in the online discovered model.
#1681 - Worked around a pre-12.2.1 WLST bug that was preventing the online tools from determining the server’s WLS version.
#1683 - Fixed a bug with the Model Help Tool where our use of JLine libraries (that only work with JDK 8 and later) were causing the Model Help tool to fail when run with JDK 7.

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.

SEVERE Messages:
        1. WLSDPLY-20008: verifySSH argument processing failed: Failed to initialize SSH context: Failed to SSH connect to host myhost.oracle.com: no such algorithm: X25519 for provider BC
```
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.
