Java Release 1.75 is now available for download.
Wednesday 21st June 2023
1.75 is a minor release. Unfortunately some Java 8 usages managed to "sneak" into the Java 5 to Java 8 jars making them less than ideal for anything other than Java 8. The 1.75 release fixes that and also a TLS issue and removes some deprecated methods and dead classes from the core ASN.1 library.
