A few weeks ago, I released STARLIGHT MINI - a great value flight computer with fully-integrated software and firmware. Unfortunately, the initial release was soured due to a supply chain issue with my PCB manufacturer. Luckily, I was able to re-order the boards as soon as I caught the issue, and I'm pleased to say that STARLIGHT MINI is back in stock!

Looking at the data, there are still tons of nodes reporting to MQTT on a /2/c/
topic instead of the newer /2/e/
format, and tons still using the old, very crowded default topic instead of a region-based one. These changes were made several firmware versions ago. Keeping your nodes updated helps the mesh stay healthy. Go update your nodes!
I'm considering in the near future ignoring the "old" MQTT topics for the map. Thoughts?
Found this note at the bottom of one of our storage bins in the back of the closet. No clue when it happened, or who it was from. But it made my day.
