Release Notes

The following are the release notes for IIZI versions in reverse chronological order.

Updating iiziGo to the latest version is easiest done using Eclipse -> Help -> Check for Updates.

This will check for updates of Eclipse, Java JustJ runtime and IIZI using the P2 repository along with potential libraries or Eclipse plug-in dependencies.

Version 4.3.0 – August 2025

As of 26th of August 2025, the IIZI version is based on Eclipse 2025-09 M3 (4.37), OpenJDK 21.0.8 (Eclipse Temurin - JustJ), and Jetty 12.1.0. The minimum Java version is 21 LTS to run IIZI.

The IIZI Designer comes bundled with Tabnine: AI-powered Assistant, for for chat and code completion for 80+ languages and frameworks including Java, JavaScript, Python, PHP, Go, and more...

IIZI version 4.3 is updated to the Jakarta EE 11 framework (jakarta.*) using Jetty 12.1 webserver.

Eclipse Jetty is a lightweight, highly scalable, Java-based web server and Servlet engine. Jetty's goal is to support web protocols (HTTP/1, HTTP/2, HTTP/3, WebSocket, etc.) in a high volume low latency way that provides maximum performance while retaining the ease of use and compatibility with years of Servlet development. Jetty is a modern fully asynchronous web server that has a long history as a component oriented technology, and can be easily embedded into applications while still offering a solid traditional distribution for webapp deployment.

It also comes bundled with Tabnine: AI-powered Assistant, for chat and code completion for 80+ languages and frameworks including Java, JavaScript, Python, PHP, Go, and more...

Version 4 is in a beta stage and comes for Windows (64-bit Intel and ARM64), macOS (Intel + Apple Silicon) and Linux (x86_64 and Aarch64).

In Java version 24 (or better) the Virtual Threads is enhanced to a new degree (without "pinning"), enabling it enhanced support of many more physical concurrent clients per Java Virtual Machine. We recommend that all customers switch to that JVM 24 or better.

All external library dependencies are updated to the latest available versions.

Version 3.3.0 – March 2023

Deprecated: use version 4.

IIZI version 3 is updated to the Jakarta EE 9 framework (jakarta.*) from the previous Java EE 7+ using the javax.* packages used in IIZI versions 1.x and 2.x.

Version 3.3 is in Milestone 1 stage and will come for Linux (x86_64 and Aarch64), macOS (Intel + Apple Silicon) and Windows (64-bit).
