Upgrading from 3.1.5 to 3.1.6

+

Before performing an update you should take your site offline by +replacing the index.php file with a static one.

+
+

Step 1: Update your CodeIgniter files

+

Replace all files and directories in your system/ directory.

+
+

Note

+

If you have any custom developed files in these directories, +please make copies of them first.

+
+
+
+

Step 2: Remove usage of the APC Cache driver (deprecation)

+

The Cache Library APC driver is now +deprecated, as the APC extension is effectively dead, as explained in its +PHP Manual page.

+

If your application happens to be using it, you can switch to another +cache driver, as APC support will be removed in a future CodeIgniter +version.

+
+

Note

+

The driver is still available, but you’re strongly encouraged +to remove its usage sooner rather than later.
