Release Notes

This release provides the following bug fixes and improvements:

  • Update Install4J to bundle Adoptium JDK 11.0.31+11 instead of JDK 1.8. OWS and ITW continue to be compiled with Java 1.8. This has no effect on the launched application as they determine their own JRE. Currently OWS officially supports Java 1.8 - 21 for launching applications. The 32 bit OWS installer for Windows has been discontinued because Adoptium does not support 32 bit JDK 11 any more.
  • Address SAST/SCA CVEs in OWS and ITW.
  • Upgrade Mozilla Rhino to v1.7.15.1 which fixes some vulnerabilities.
  • Fix the bug that OWS does not prompt for Proxy Authentication when launching the Jnlp application (stage2).
  • Update documentation.
  • Update versions of JVMs in jvms.json on the JVM download server.

Installer type: exe
