The following are the release notes for IIZI, listed in reverse chronological order.
IIZI version 4.6 has been updated to the Jakarta EE 11 framework (jakarta.*), running on the Jetty 12.1 web server and Java 25 LTS as minimum requirement.
Eclipse Jetty is a lightweight, highly scalable, Java-based web server and Servlet engine. Jetty is designed to support modern web protocols (HTTP/1, HTTP/2, HTTP/3, WebSocket, and others) with high throughput and low latency, delivering maximum performance while retaining ease of use and compatibility with decades of Servlet development. As a fully asynchronous, component-oriented web server, Jetty can be embedded directly into applications while still providing a robust standalone distribution for traditional web application deployment.
The iiziGo Designer ships with Tabnine, an AI-powered assistant that provides chat and code completion for more than 80 languages and frameworks, including Java, JavaScript, Python, PHP, and Go.
In Java 25 and later, virtual threads have been improved to eliminate thread "pinning,"
allowing a single Java Virtual Machine to support many more concurrent physical clients.
Although IIZI is compiled for Java 25 (-release 25) and therefore ships with the
Java 25 LTS runtime from Eclipse Temurin JustJ, it runs unchanged on newer JVMs. We recommend
that customers run IIZI on Java 25 or later to benefit from these virtual-thread improvements.
The easiest way to update iiziGo to the latest version is through Eclipse → Help → Check for Updates. This checks for updates to Eclipse, the Java JustJ runtime, and IIZI itself using the P2 repository, along with any required libraries or Eclipse plug-in dependencies.
The minimum Java version required to run IIZI is 21 LTS.
Version 4.6 is currently in beta and is available for Windows (64-bit Intel and ARM64), macOS (Intel and Apple Silicon), and Linux (x86_64 and AArch64).
As of July 20, 2026, IIZI is built on:
Both the iiziGo Designer and the iiziServer now requires Java 25 or better.
As of July 8, 2026, IIZI is built on:
Both the iiziGo Designer and the iiziServer run well on Java 25.
We replaced our previous JavaScript compressor with a more efficient toolchain and updated the build to Tycho 5.0.3 for Maven, along with the latest Android and iOS SDKs. The entire UI has been recompressed: JavaScript is transpiled and minified to the ECMAScript 2020 target using a combination of Google's Closure Compiler and Terser, each applied to different parts of the codebase. HTML is minified with HTML-Minifier-Terser and CSS with Lightning CSS, and SVG files are minified as well.
The IIZI web server now supports GZIP, Brotli, and Zstandard compression
on both the server and client sides. During the build, all eligible files
(selected by file type and minimum size) across the entire web server root
are pre-compressed into GZIP (.gz) and Brotli (.br)
form. Depending on the compression formats the client supports, Jetty serves
these pre-compressed files directly instead of their uncompressed counterparts.
As of 29th of May 2026, the IIZI version is based on Eclipse 2026 RC (4.40 – GA version released 11th of June 2026), OpenJDK 21.0.11 (Eclipse Temurin - JustJ), and Jetty 12.1.9. We also replace our JavaScript compressor for a more efficient one (Terser), updated building with latest Tycho 5.0.3 for Maven, and the SDK's for Android and iOS. Our entire UI has been recompressed with Terser. So now we use Google's Closeure-Compiles and Terser for JavaScript compression (transpiling) and minification.
As of 25th of May 2026, the IIZI version is based on Eclipse 2026-06 M3 (4.40), OpenJDK 21.0.11 (Eclipse Temurin - JustJ), and Jetty 12.1.9.
As of 18th of April 2026, the IIZI version is based on Eclipse 2026-06 M1 (4.40), OpenJDK 21.0.10 (Eclipse Temurin - JustJ), and Jetty 12.1.8.
As of 7th of April 2026, the IIZI version is based on Eclipse 2026-03 GA (4.39), OpenJDK 21.0.10 (Eclipse Temurin - JustJ), and Jetty 12.1.8.
