September’s Open Source Releases
Fall brought a wave of major version updates across the open source ecosystem, from Python machine learning tools to React UI libraries and VS Code extensions. Here’s a look at what shipped in September.
Rowy 2.0
Rowy is an open source platform that brings a spreadsheet-like interface to Firebase’s Firestore database. The 2.0 release adds a new UI for interacting with your database, one-click deployment, and integrations with tools like Twilio, Slack, and Algolia. It’s positioned as a low-code option for building on Google Cloud Platform, letting you write cloud functions directly in the browser.
Tweepy 4.0
If you write Python for Twitter integrations, Tweepy’s latest release brings support for Twitter’s API v2. The update reworks parts of the API, adds async streaming, ships new documentation, and now supports uploading videos and larger GIFs.
Dash 2.0
Dash, the Python framework for building data science and machine learning web apps on top of Flask and React, hit version 2.0. This release focuses on performance improvements and UI updates, and adds Markdown code highlighting support for F#, C#, and MATLAB.

SciKit-Learn 1.0
The first official 1.0 release of scikit-learn is out. The Python machine learning module, built on SciPy, provides tools for predictive data analysis including model fitting, data processing, model selection, and evaluation. It includes extensive visualizations and is a staple for building efficient ML pipelines.

PyG 2.0
PyTorch Geometric (PyG) 2.0 is a major update to the library for writing and training graph neural networks on PyTorch. The project has also moved to its own GitHub org. New in this release is sophisticated heterogeneous graph support, GraphGym integration, and additional deep learning features for graph and irregular structure data.
MUI 5.0
Formerly known as Material-UI, MUI 5.0 lands with a fresh name and updates to its React component library. MUI is used by companies like Spotify, Amazon, NASA, and Netflix, and offers foundational and advanced components for building React apps. Version 5.0 focuses on documentation and core library improvements.
Cal.com 1.0
The first full release of Cal.com brings an open source scheduling assistant that handles meeting coordination, including timezone conflicts. The tool covers appointments like meetings, seminars, and family calls, and can be self-hosted or run through Cal.com’s hosted service.

MonitorControl 3.0
Apple users who work with external displays will want MonitorControl 3.0. The tool adds control for external display brightness and volume from the task bar, behaving like a native setting. This update brings support for Apple Silicon, additional UI options, and a new app icon.
Q1K3
A standout from the js13kgames competition, Q1K3 is a Quake remake written in JavaScript with a total game size of under 13 kilobytes. Despite the size, it packs enemies, weapons, graphics, and music. It’s worth playing and reading about how it was built.
