Attachment Mod Version 2.4.0 released

Due to the release of phpBB 2.0.18, a few bugs and some security concerns a new attachment mod version has been released.
This release is an overhaul of the codebase, including the mechanism used in olympus to sanitize input.

Please update your Attachment Mod to version 2.4.0 as soon as possible. You are able to use the changed files only package
if you haven't modified any attachment mod files or the patch file package if you are familiar with patch files.
The code changes tutorial for this mod version are not made available due to the vast amount of small changes.
I suggest using the patch method here if you have a heavily modified attachment mod in use.

This Mod adds the ability to attach files in phpBB2.
This Version will NOT work with phpBB2 Modules designed for *Nuke Portals. Those working with *Nuke Portals are ports and will
be not supported.

As with phpBB, there are three different packages available:

"Full Package" contains entire Attachment Mod source.
"Changed Files Only" contains only those files changed from previous versions of Attachment Mod. Please note this archive contains changed files for [b]each[/b] previous release (version 3 and 4).
"Patch Files" contains patch compatible patches from the previous versions of Attachment Mod.
