ZeroTier Release Notes$$$2025-08-21 -- Version 1.16.0$$$License Changes$$$The core (node/ and include/) and the service (service/ and osdep/) are now under the Mozilla Public License (MPL).$$$The network controller (controller/) is now under a commercial source-available license.$$$Use make ZT_NONFREE=1 to build non-MPL components.$$$Building with ZT_NONFREE=1 changes the license of the resulting executable to a proprietary commercial license vs. MPL.$$$Default binary builds no longer contain the controller.$$$$$$Network-Specific Relays (preview / beta)$$$$$$It is now possible to designate one or more nodes as network-specific relays to be used in preference to roots for relayed traffic between members of a network. These nodes need not necessarily be members of the network.$$$Moons are now considered even more extra deprecated and should not be used in new deployments.$$$We will announce support for network-specific relays once we have worked with some users to test and performed more internal validation.$$$HELLO packet encryption is now available by enabling the encryptedHelloEnabled settting in local.conf.$$$$$$HELLO packets contain no data; only public keys and very basic meta-data like protocol version information.$$$Most users wont care about this; but if you require this for e.g. compliance reasons you can enable.
