68<p>Replace the following directories in your "system" folder with the new versions:</p>

70<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
71
72<ul>

80<h2>Step 2: Update your config.php file</h2>
81
82<p>Open your <dfn>application/config/config.php</dfn> file and add this new item:</p>

88| Output Compression
89|--------------------------------------------------------------------------
90|
91| Enables Gzip output compression for faster page loads. When enabled,
admine334c472006-10-21 19:44:22 +0000[diff] [blame]92| the output class will test whether your server supports Gzip.
admin0f3ce632006-09-22 00:11:50 +0000[diff] [blame]93| Even if it does, however, not all browsers support compression
94| so enable only if you are reasonably sure your visitors can handle it.
95|
96| VERY IMPORTANT: If you are getting a blank page when compression is enabled it
97| means you are prematurely outputting something to your browser. It could
admine334c472006-10-21 19:44:22 +0000[diff] [blame]98| even be a line of whitespace at the end of one of your scripts. For
admin0f3ce632006-09-22 00:11:50 +0000[diff] [blame]99| compression to work, nothing can be sent before the output buffer is called
100| by the output class. Do not "echo" any values with compression enabled.

109<h2>Step 3: Rename an Autoload Item</h2>
110
111<p>Open the following file: <dfn>application/config/autoload.php</dfn></p>
112
113<p>Find this array item:</p>
114
115<code>$autoload['core'] = array();</code>
116
117<p>And rename it to this:</p>
118
119<code>$autoload['libraries'] = array();</code>
120
121<p>This change was made to improve clarity since some users were not sure that their own libraries could be auto-loaded.</p>

127
128<h2>Step 4: Update your user guide</h2>
129
130<p>Please also replace your local copy of the user guide with the new version.</p>
