Baseline browser support

tmedwards commented 4 years ago

It's time to change SugarCube's baseline browser support.

Consider changing the baseline browser target to:

Internet Explorer 11. For reference, v2's baseline target is IE 9.
Browsers that support ES2015 (ES6). This pretty much means dropping ancient browsers altogether.

How well does the Twine 2.x application's Test and Play options handle ES6 code?

The question is essentially moot for non-browser-shell Twine 2 releases as they all open in users' browsers, which puts the onus on the browser.

For the browser-shell releases, it depends on whether we're talking pre- or post- Twine 2 v2.3.

Post-v2.3 also makes the question moot, since releases now open new system-default browser windows for testing. Thus, the onus is again on the browser.
Pre-v2.3 releases do test within a new shell window, but AFAIK all of the shells supported ES2015—or, at least, since v2.1–2.2; I'm not worried about v2.0.

Make sense?
