Date: Fri, 9 Mar 2012 17:03:37 +0000
Subject: Bumped CodeIgniter's PHP requirement to 5.2.4. Yes I know PHP 5.4
 just came out, and yes I know PHP 5.3 has lovely features, but there are
 plenty of corporate systems running on CodeIgniter and PHP 5.3 still is not
 widely supported enough. CodeIgniter is great for distributed applications,
 and this is the highest we can reasonably go without breaking support. PHP
 5.3 will most likely happen in another year or so. Fingers crossed on that
 one anyway...

Subject: Direct return from mimes config, instead of using global $mimes;
 Global variables are generally a terrible idea, especially for something as
 simple as this. The mimes.php now returns an array instead of just injecting
 a variable name into the global namespace.

Subject: Added get_mimes() function to system/core/Commons.php.The MIMEs array
 from config/mimes.php is used by multiple core classes, libraries and helpers
 and each of them has implemented an own way of getting it, which is not

Subject: Fix #2822: Incorrect usage of fwrite()

We only used to check (and not always) if the return value of fwrite() is boolean FALSE,
while it is possible that the otherwise returned bytecount is less than the length of
data that we're trying to write. This allowed incomplete writes over network streams
and possibly a few other edge cases.
