Contributors to this patch versions, from both the Core team and the community at large: Pierre RAMBAUD, Pablo Borowicz, Axome, Jáchym Toušek, okom3pom, Thomas N. Thank you! Two of you contributed for the very first time, warm welcome :-)

A very special thank to Charles Fol from Ambionics for the security report!

Since version 1.7.3.4 is a “patch” update to version 1.7.3.3, upgrading from any 1.7.3 version will be easy: features will work better, and modules & themes which worked fine on 1.7.3.x will work just as well with 1.7.3.4.
Upgrades from a standard 1.7.x version should work just as well.

This the same for 1.6.1.20 regarding 1.6.1.x versions.
