<p>Version 2.0.0 brings a non-backwards compatible change to

get_dir_file_info() in the <a class="reference internal" href="../helpers/file_helper.html"><em>File

|
are extremely rare in CodeIgniter, but this one we feel was warranted
|
|
due to how easy it was to create serious server performance issues. If
|
|
you <em>need</em> recursiveness where you are using this helper function,
|
|
change such instances, setting the second parameter, $top_level_only

to FALSE:</p>

<p>2.0.0 gets rid of the “Plugin” system as their functionality was
|

identical to Helpers, but non-extensible. You will need to rename your

plugin files from filename_pi.php to filename_helper.php, move them to

|

<p>The Encrypt library has had a number of improvements, some for

|
encryption strength and some for performance, that has an unavoidable
|
|
consequence of making it no longer possible to decode encrypted data
|
|
produced by the original version of this library. To help with the
|
|
transition, a new method has been added, encode_from_legacy() that
|
|
will decode the data with the original algorithm and return a re-encoded
|
|
string using the improved methods. This will enable you to easily
|
|
replace stale encrypted data with fresh in your applications, either on
|
|
the fly or en masse.</p>
