First, I wanted to thank you for continuing to maintain NetPanzer after all these years.
As of last year, I have taken over as lead upstream maintainer of NetPanzer, which is included in the Debian distribution. I was working closely with a previous maintainer of the official NetPanzer project, however I am sad to say they recently passed away. With his passing, access to the SourceForge project page is no longer possible. The official project repository is now at https://github.com/netpanzer/netpanzer
Primarily at this point, I'm writing to request that 'src/NetPanzer/Interfaces/GameConfig.cpp' be patched to include 'nepanzer.io' as the masterserver (L367). I'm hosting that server and I plan to keep it running indefinitely. Today, 0.8.7 is effectively unplayable, since the master server has been down for several years.
We are planning a new 0.9 release as well and hope to have it ready in roughly two months. Please let me know if there are any concerns or specific people I should discuss this with - thank you!
