The full changelog from JES 4.3 is given in jes/help/JESChangelog.txt, but the highlights include:

• Upgrading the Jython interpreter to version 2.5, making available new language features and speeding up many user programs.
• Adding code to JES and the installers to support double-clicking .py files to open them in JES, on all supported platforms.
• Bundling JMusic and the Jython Music libraries, allowing JES to be used with the text "Making Music with Computers" by Bill Manaris.
• Adding a plugin system that allows developers to easily bundle libraries for use with JES.
• Fixing the Watcher, so that user programs can be executed at arbitrary speeds.
• Adding new color schemes for the Command Window, which allow users to visually see the difference between return values and print output.
• Fixing numerous bugs.
• Correcting the spelling of "Loading Program."
