[Any other "most notably" changes?]

Subject: IMP 2.2.4 (SECURITY) released

The Horde team announces the availability of IMP 2.2.4 -- this version
improves IMP's filtering of malicious HTML scripting constructs in HTML
attachments, which can be used by an attacker to run scripting code in
the user's browser.  Administrators of IMP 2.2.x production systems are
encouraged to upgrade to prevent this kind of attack against your users.

This release also contains a long list of bug fixes and minor improvements,
most notably the fix for attachment downloading for IE 5.5 users.  For a
complete list of changes in this release, please consult the docs/CHANGES
files.

Credits:

Thanks to Nick Cleaton <nick@cleaton.net> for reporting the HTML scripting
vulnerability.  A specific exploit for this problem is known, but at
his request we are not providing details at this time.  Other webmail
products are also vulnerable to a similar attack, and this will give
their developers a little more time to implement a fix.

Please notify <security@horde.org> of security issues related to Horde
and IMP.

I'd like to see this read "Administrators of IMP 2.2.x productions systems who 
have enabled reading HTML email are ...", since we do have it disabled by 
default.
