CockroachDB relicensed

The CockroachDB database management system has been
relicensed; the new license is non-free. 'CockroachDB users can
scale CockroachDB to any number of nodes. They can use CockroachDB or embed
it in their applications (whether they ship those applications to customers
or run them as a service). They can even run it as a service
internally. The one and only thing that you cannot do is offer a commercial
version of CockroachDB as a service without buying a license.'
