Test, test everywhere!
It is very important to test our releases!
Please make sure to test all the platforms we support. They're a lot, but it's doable. We can use VMs if needed.
32-bit tests are the less likely to happen, but we should try to test them nonetheless, since we still support them.
TZP is a marvellous site to test stuff. Be sure to check all indicators are green. No red ones. Double, triple check the red ones!
But this site is also very useful. I did my best to make it. And please, be sure to check it every now and then, as it might contains very useful updates. I must say the title is now a bit reductive, since it isn't only about onion sites, but it's also about several features of our browsers.
At the moment it's all static HTML content, but one day it might have more. For example, I might provide a first-party WebSocket test. But PHP shall not pass in this server. Node.js and Python are fine though.
