Release Radar • March 2024 Edition

Some of you around the world may have been eating chocolate this past week. Others might be enjoying the last few weeks of snow. Regards, developers everywhere are hard at work, shipping new updates for open source projects. There are all kinds of projects receiving new versions, from weekend hobbies to world changing technology. It's our job to find them, and showcase some of our favourites, so here are our staff for this month's Release Radar.

FusionCache 1.0

Want an easy to use cache with advanced resiliency features? Look no further than FusionCache. It's built for performance, good refresh rates, better auto-setup, better logs, and more. Congrats to the team on shipping your first major and stable version 🎉 and receiving over 3.8 million downloads.

Yes I know this was shipped in February, but since I'm in Australia and live in the future, it was shipped on 1st March for me, so I'm including it here in the March Release Radar 😉.

Brainchop 3.0

We featured Brainchop back in the February 2023 Release Radar. Since then, Brainchop is back with a powerful model update. Brainchop is a 3D MRI rendering and segmentation tool for analysing and processing Magnetic Resonance Imaging (MRIs) of various brains. Using AI, the new version features three classes of models for processing and analysing images of brains. Here are the three new models:

Carapace 1.0

It's exciting when something breaks out on its own, and that's what's happened with Carapace. Originally part of a 13-piece project, it now has a major first version and it's a multi-shell completion library and binary. Carapace consists of a pflag fork, a yaml spec, a shell lexer, a completion bridge and various scrapers. Congratulations to the team on shipping your first version 🥳.

Storybook 8.0

If you're into UI development, then you need to know about Storybook. It's a frontend workshop for building UI components and pages in isolation. The latest version brings some big improvements for testing and documentation with built-in visual testing. There's also React Server Component support, improved controls for React and Vue projects, as well as improved Vite architecture, Vitest testing, and Vite 5 support. Check out all the major changes in the Storybook changelog.

Moby 26.0

Having been featured in our February 2023, and January 2024 Release Radars, Moby is the original Linux Container runtime. This new version adds a bunch of changes to the Docker CLI and Moby itself with additional features. There's bug fixes and enhancements, with the main thing for users to be on the look out for containers that were created using Docker Engine 25.0.0. These containers might have duplicate MAC addresses, and thus must be recreated. The same goes for those containers created with Moby 25.0+ and with user defined MAC addresses. Read up on all these changes in the release notes.

PixiJS 8.0

If you're into video game dev, then PixiJS is something you need to know about. It's a HTML5 game engine that provides a lightweight 2D library across all devices. This latest update has a new package structure, custom builds, graphics API overhaul, and lots more. You can read about all these changes in the PixiJS Migration Guide. Also big congrats to PixiJS for being part of the open source community for ten years now! 😮.

Babylon.js 7.0

It's been around for a while, and we've featured it in the April 2019 and March 2022 Release Radars. It's also been in GitHub Game Bytes and on our latest episode of The Download. Yes, I'm talking about Babylon, the powerful web rendering engine for all kinds of graphics. The newest update includes support for basic Global Illumination, a highly requested feature. Read more about other cool new additions including Gaussian Splatting, Ragdoll physics, Procedural Geometry and all the breaking changes in the Babylon release notes.

tabler-icons 3.0

Use Tabler Icons for over 5200 pixel perfect icons designed for the web. This latest set expands the library further with 244 new icons. There's also more support backward compatibility, and more design options for webs, mobile, and desktop applications. All icons now also come in both outlined and filled versions to suit even more preferences and requirements. Check out all the icons on the website.

Gleam 1.0

Want a friendly language for building safe systems at scale? Gleam is here for you. It features modern and familiar syntax, that's reliable and scalable. Gleam runs on an Erlang virtual machine, and can run plenty of concurrent tasks. It comes with a compiler, build tool, formatter, editor integrations, and package manager all built in so you can get started right away. Congrats to the team on shipping your first major version 🙌.


Haystack 2.0

People like to be on the AI bandwagon, but to have good AI models, you need good LLM (large language models). Welcome to Haystack, it's an end-to-end LLM framework that allows you to build applications powered by LLMs, Transformer models, vector search and more. The latest version is a rewrite of the Haystack framework, and includes a new package, powerful pipelines, customisable components, prompt templating, and more. Read all about them in the Haystack release notes.

🔍 LLM orchestration framework to build customizable, production-ready LLM applications. Connect components (models, vector DBs, file converters) to pipelines or agents that can interact with your data. With advanced retrieval methods, it's best suited for building RAG, question answering, semantic search or conversational agent chatbots.
