About the 3.3 update

Hi everyone,

* I've checked the files in the latest-version.zip file, and I found no changes in the next files:

admin > templates > css > chartist.css
admin > templates > css > mobile.css
admin > templates > js > plugins > sortable.js
admin > templates > js > jquery.js
admin > templates > _header.php
admin > templates > login.php
control > classes > certs > cacert.pem
control > classes > mailer > src > Exception.php
control > classes > system > class.cleantalk.php
control > classes > class.gateway.php
control > system > gateway > refunded.php
control > system > modules > rss.php
control > system > _ajax.php
control > tcpdf > tcpdf.php
content > language > english > add.php
content > language > english > global.php
content > _theme_default > header.tpl.php

I don't know if this is intended, or just a "slip".

* * Updated Open Graph, Twitter Cards etc to use event thumbnail rather than default image. Thumbnail must be 200x200 or greater.
If the thumbnails are less than 200x200, why don't use the original image itself? It'll will have a best resolution and size...

* The new version of normalize.css (v8) included in this update:
"Remove support for older browsers Android 4, lte IE 9, lte Safari 7."
It'll be great to warn the webmasters before the update wink

* The CSS files, and the JS files, aren't minified, and now it's a MUST to improve the speed of websites. It'll be great to have the same files with a .min version.

* In the "CSS File Changes" of the "Software Upgrade - v3.3" documentation, there are more changes that are missing:

.footbar .date {
  text-transform: capitalize;
}
.eventarea .details .date {
  text-transform: capitalize;
}
.event_calendar .dayviewarea .noevents {
  font-style: italic;
  font-size: 12px;
}
.eventpagearea .bottom .text .highlight {
  color: #008198;
  text-transform: capitalize;
}

*  Why are we keeping the local JS/CSS files when we could use the CDN ones?:

Faster for the visitor, and less CPU/RAM for the web server wink
