Supported web browsers

It seems we are targeting very recent Firefox and Chrome versions. It would be good to better define what's our browser compatibility target.

That's a good point. We have had informal compatibility targets a year ago, particularly regarding display resolution, based on the demography we observe on our traffic @ landing and blog websites.

But it is true that this policy should be a company/product-wide requirement. We will check again how are ours stats regarding that to target X% (e.g. 95%+) and adapt with some heuristics or other stats on top to be a bit broader (e.g.: more users are more likely to be using Windows than our current visitor user base shows).

Sure. Also we'll need different targets for landing/blog and gitbase-web/bblfsh-web. I think it's safe to assume that the later could support less browsers (it's already the case).

@smola from https://github.com/src-d/product/issues/302#issuecomment-455313094:

Browser support

Browser	Min version
Chrome	68
Firefox	62
Safari	12

Note: Not adding IE/Edge support because of data, but this could eventually change in the future if becomes a requirement for certain web products running on enterprise settings. On the bright side, MS pushing for Windows updates more aggressively and dropping the Edge engine in favor of Chromium should help it in the long run.

Desktop display support

Dimension	Minimum
X	1280 px
Y	768 px
Color	24 bit

Mobile display support (whenever applicable)

Dimension	Minimum
X	360 px
Y	640 px
Color	24 bit

Looking at the data segmented by month, it looks like 2 latest for Chrome, 1 latest for Firefox and 1 latest for Safari would cover pretty much our current audience (82%). And 3 latest for Chrome, 2 latest for Firefox and 2 latest for Safari if we want to be more conservative (86%).
