**Welcome to the second edition of OSL Monthly Updates.**

October’s update highlights progress across the Open-Source Leg ecosystem from software improvements to community initiatives and new ways to stay connected.

* * *

### Software Update: OSL v3.4.2 Now Live

The latest update introduces several key refinements:

- Fixes a bug in the _motor constants dictionary_, where derived constants now correctly use a torque constant of 0.11.
- Adds missing _UV installation steps_, including adding UV to the system path.

You can find the update on [PyPI](https://pypi.org/project/opensourceleg/).

### Community and Outreach

We’ll soon host our first **community meeting (TBD)**, an open session where you can hear about the latest updates from the OSL team. If time allows, we’ll close with a short Q&A.

Our **first OSL newsletter** also saw strong engagement from across the research community. If you missed it, you can read the launch issue here: [OSL Newsletter #1](https://drive.google.com/file/d/1YkQVKtwM3wDUP2sMifc9H9a22MfMdHhp/view?usp=sharing). _(A subscription option will soon be added to the website for anyone who didn’t receive it.)_

### Research Publications

Researchers can now **upload their own OSL-related papers** directly to the website. Sharing your work helps others learn from your experience and highlights how the Open-Source Leg is being used across labs worldwide.

Upload your publication on the _Research_ page at [opensourceleg.org/research](https://opensourceleg.org/research).
