Drop any cookies set when static Google Tag Manager JavaScript is read from cache (fixes issue where it sometimes couldn't be cached by Cloudflare because a cookie was set)
Using js_url() on Analytics JavaScript (adds ability to leverage Early Hints/preloading URLs when using Cloudflare addon)
Fix for XenForo 2.3 where date presets drop-down wouldn't change the date on reporting
Require XF 2.2 or higher (incompatible Mailer class between XF 2.1 and 2.2)
Use <xf:fa /> for the staffBar now that XF requirement is 2.2+ (better compatibility with Font Awesome Manager)
If you aren't using Font Awesome Manager, nothing really changes with this update (if you were using XF 2.0 or 2.1, you would have gotten errors before, now it simply doesn't let you install unless you have XF 2.2).
Google Analytics changed what dimensions are compatible and no longer allow full page URL to be used in conjunction with most other dimensions/metrics. Because of that, we are switching to something that works reasonably well as far as compatibility in reporting (page path).
