Since my last post, the Rayhunter project has made significant progress.

# Introduction

The patches for the TP-Link M7350 router have been merged into the upstream Rayhunter repository and the device is listed as recommended for European users.
m0veax gave a talk (https://media.ccc.de/v/2025-537-exploring-tp-link-m7350-porting-rayhunter/playlist) on the project at the MRMCD, which presented great insights into how the development happened. I can highly recommend watching the talk if you are interested in the project.

# Updating Rayhunter

As the TP-Link M7350 patches have been merged, running a custom build is no longer necessary to use Rayhunter on this device.
As such, I removed the old version of Rayhunter on my device and simply used the installer from the latest version from the repository (0.10.1 as of writing this post).
I had an issue that the installer did not create a default configuration file, so I had to create one myself, where I simply set device = "tplink".

# New features

The latest version has made quite a lot of improvements:

- New heuristics (https://efforg.github.io/rayhunter/heuristics.html)
- Improved web interface
- On-device animation / logos

## New heuristics

The most important new feature is the new heuristics. Read up on the heuristics in the Rayhunter documentation (https://efforg.github.io/rayhunter/heuristics.html). I have not yet encountered any warnings, but I will continue to run Rayhunter and report any findings.

## New web interface

The web interface has been improved significantly with a new design and better usability.

## On-device logos

It is now possible to display various logos and animations on the device's screen.

# Conclusion

Thanks to the great work of everyone involved, stingray detectors are now more accessible than ever. This project is making very good progress. I recommend everyone to watch m0veax's talk (https://media.ccc.de/v/2025-537-exploring-tp-link-m7350-porting-rayhunter/playlist) and read EFF's post (https://www.eff.org/deeplinks/2025/09/rayhunter-what-we-have-found-so-far) on the Rayhunter.
