What's new in this version:

New Features:
install/install ➜ Adding Debug Log Files in macOS for Java Updater and JCP (JDK-8319745 (not public)):
- Debug log files for Java Updater and JCP have been added to the directory $HOME/Library/Application Support/Oracle/Java/Java Updater/ for macOS x64 and aarch64. Logs for Java Updater and JCP are separated into two log files: JavaUpdaterLog.txt and JCPUpdateLog.txt.
- JavaUpdaterLog.txt is generated and logs debug lines if it does not already exist when Java Updater is run. Likewise, JCPUpdateLog.txt is generated and logs debug lines if it does not already exist when Java Control Panel is run.
- If a log file already exists for Java Updater or JCP, the newly logged debug lines are appended at the end of the log file. Each log session has a header with a timestamp of when the application was run.

security-libs/java.security ➜ New Security Category for -XshowSettings Launcher Option (JDK-8281658):
The -XshowSettings launcher has a new security category. Settings from security properties, security providers and TLS related settings are displayed with this option. A security sub-category can be passed as an argument to the security category option. See the output from java -X:
- -XshowSettings:security
- show all security settings and continue
- -XshowSettings:security:*sub-category*

show settings for the specified security sub-category and continue. Possible *sub-category* arguments for this option include:
- all: show all security settings and continue
- properties: show security properties and continue
- providers: show static security provider settings and continue
- tls: show TLS related security settings and continue
- Third party security provider details will be reported if they are included in the application class path or module path and such providers are configured in the java.security file.
