The following are the release notes for IIZI versions in reverse chronological order.
IIZI version 4.5 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.
The iiziGo 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...
In Java version 25 (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 25 or better.
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.
The minimum Java version is 21 LTS to run IIZI.
Version 4.5 is in a beta stage and comes for Windows (64-bit Intel and ARM64), macOS (Intel + Apple Silicon) and Linux (x86_64 and Aarch64).
As of 2nd of June 2026, the IIZI version is based on Eclipse 2026 RC (4.40), OpenJDK 21.0.11 (Eclipse Temurin - JustJ), and Jetty 12.1.10. 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 and Lightning CSS. So now we use Google's Closeure-Compiles and Terser for JavaScript compression (transpiling) and minification to ECMASCRIPT_2020, HTML, SVG files are also minified.
The IIZI web server now also supports GZIP, Brotli and Zstandard compression for server and client side, and the build system precompresses all file "candidates" (file type and minimum size) in .gz (GZIP) and .br (Brotli) form for the entire web server root. They are also served directly by Jetty instead of the non-compressed file, depending on client compression support.
