Two major changes here:
1. No longer include the instructions in comments. Quite often the filled in template was also in comments then because people don't know the HTML formatting. Also if the template is not completely filled in now, public shaming ensues.
2. The reproduce steps for bugs now suggest a numbered list of steps. Hopefully this will improve the bug reports we get with better reproduction steps.
We don't usually need to know what specific Qt version or graphics driver the user has, and it's a great hassle for the user to figure this out, especially when they aren't technical and just installed an official release.
I hope that this leads more bug reporters to actually fill in the template.
