IPS Community Suite 4 Release Notes
4.0.3 - 1 May 2015
Many bugs fixed both from tickets and bug tracker. A focus on ticket-related issues.
Many performance improvements. More will come in next release but you should see a difference.
The support tool in the AdminCP will now do MD5 checksum on all PHP files on the system. This allows the system to detect any modified PHP files which is useful both for support and for security. The master checksum values are fetched remotely from IPS to ensure the list is not tampered with locally.
