Subject: Re: [zeromq-dev] Clarification of libzmq license

libzmq has been safe to use in commercial applications since we switched from GPL to LPGL before version 1.0. The static link exception means you don't need to provide libzmq as a DLL, you can create a fully linked static binary. The additional text I wrote was to clarify what this exception meant.

So yes, 3.2.x has exactly the same license as 4.x and you can use it in your commercial applications.
