Breaking changes to know before you upgrade

  • Java 17 is now the minimum. Older JVMs are no longer supported. Later Java LTS versions should work but are not officially tested.
  • Xerces and xml-apis are removed. Custom code that imports org.apache.xerces.* directly needs to migrate to javax.xml.parsers.* and org.xml.sax.*.
  • Logins are case-insensitive by default. Existing accounts with case-sensitive usernames continue to work via a compatibility path.

Installers remove the prior release during an upgrade, preserving directories that should persist (such as appdata, conf, extensions, and logs).

New features

  • serverName variable in alert templates, useful for multi-instance deployments.
  • Environment variable substitution in CLI config files.
  • JavaScript pretty-printer for formatting JS directly in the editor.
  • Toggle Comment action in the editor’s right-click menu.

Notable fixes and improvements

  • Migration failure when upgrading to 4.5.2 is resolved.
  • JXTreeTable.getEditingRow bug fixed, which addresses a class of macOS client errors.
  • Clipboard error on Linux when an image was on the clipboard is fixed.
  • Potential data loss when saving plugin properties is fixed.
  • HTTP parameter map order is now preserved, so code that depended on the previous non-deterministic ordering may behave differently.
  • Message search performance improved by caching ResultSet metadata, and extension load is faster.

Security

This release remediates 24 known CVEs (1 Critical, 10 High, 12 Medium, 1 Low) through dependency upgrades, including log4j, the PostgreSQL JDBC driver, jSch, commons-lang3, and commons-text.
