Stringer Java Obfuscator 2.1.3

We’re delighted to share the latest version of Stringer - the best-in-class Java Obfuscator/Protector.

So, what’s new?

All protection mechanisms have been significantly improved, protection time has been optimized, and some minor issues have been fixed.

A quick note about some important changes to our licensing policy:

We’re happy to say that you don’t need to buy a new license when a new version of Stringer comes along. You just need to have a valid license and an active support subscription - then you’ll be able to receive the upgrade for free.
