@mbabker any idea why the test on AppVeyor failed?

1. JCacheStorageCacheliteTest::testCacheTimeout
   Some data should be available in lifetime.
   Failed asserting that false matches expected 'testData'.
   C:\projects\joomla-cms\tests\unit\core\case\cache.php:121
   C:\projects\joomla-cms\tests\unit\suites\libraries\joomla\cache\storage\JCacheStorageCacheliteTest.php:67

False positive, especially since the other two builds did pass. Anyway I triggered a rebuild.

@mbabker could it be that this result into an B/C change? Because # is different in regex than / I'm notice this because the examples have been changed too. Or is this just me who knows nearly nothing about regex?

You're asking the wrong person. I branched the original PR, resolved merge conflicts, and opened a new one.

Likewise, plugins don't fall under the same B/C scrutiny as the core API. Plus cache is flushed on an update. So I'm not quite sure what the B/C concern here could be.

Well my point is that it it looks like the old configuration value (\/component\/users\/) does not work anymore but i have no idea if that is true. I have just noticed that the description was changed so better safe than sorry.
