due to rising amount of security patches (which I strongly support and be thankful for) I looked for a possibility to hide the version string of my current installation till I have got the time to upgrade. This way bots searching for vulnarable site would have it a lot harder to get the version string.
I didn't find a way to do it just for the login site (I use cookie auth) without editing the core files (main.php or index.php, I guess).
That's why I helped myself with editing the config.inc.php with the line: DEFINE('PMA_VERSION',''); which rewrites the version string applicationwide.
Since I rather want to disable the string just on the login page (authenticated users should be able to see the version) I hereby file a feature request.
