I googled that and found links to tocker.ca which seems down.

$ curl  http://www.tocker.ca/2015/08/18/a-followup-on-show_compatibility_56.html
&lt;!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"&gt;

&lt;title&gt;404 Not Found&lt;/title&gt;
&lt;/head&gt;&lt;body&gt;
&lt;h1&gt;Not Found&lt;/h1&gt;
&lt;p&gt;The requested URL /2015/08/18/a-followup-on-show_compatibility_56.html was not found on this server.&lt;/p&gt;
&lt;/body&gt;&lt;/html&gt;


Where do I see what settings/variables have changed from default one (in my setup)?

Any background about this change?
You need to enable the PERFORMANCE_SCHEMA.

See the documentation for details:


  The Performance Schema is disabled by default. To enable it, start the
  server with the performance_schema variable enabled. For example, use
  these lines in your my.cnf file:

[mysqld] 
performance_schema=ON



*Please check updated syntax from mysql website

Migrating to Performance Schema System and Status Variable Table has all the information you'd ever need on the matter.
