Version 1.0.2 brings experimental FreeBSD support. It has ONLY been tested
on FreeBSD 10 on an x64 system, and should be considered alpha for this
platform for now.
This version is not going to be pushed out to the entire world via software
update, and the binary version distributed for other platforms via the
zerotier.com web site will remain 1.0.1 as there are no other meaningful
user-facing changes. This is just an interim release to let FreeBSD users
try it out. If you find bugs, please enter them on GitHub or do a pull
request and fix them yourself.

This version is mostly a bug fix release. It fixes a bug that could cause
the service to crash on Windows while running the GUI application. It also
contains a number of fixes to the Linux installer and Linux support for
systemd-based init systems.
It also includes a minor tweak to the multicast algorithm. Version 1.0.0
sent multicasts in a deterministic order, while this version randomizes
the order. The vast majority of users will notice nothing, but this may result
in superior coverage for service announcements on very large networks. It's
a hard variation to test, so we're releasing like this to gather information
from users about the effect. Nothing will change on small networks, and
ordinary multicast functions like ARP and NDP should be unaffected.
The next version will likely focus on additional improvements to Microsoft
Windows support, since there are several known Windows issues in need of
attention. We're working on an NDIS6-based Tap driver that should address
the driver issues experienced by a small number of Windows 7 users.
This should not affect most users, but on large networks it should cause service
announcements to work a lot better. This is the result of a prolonged discussion
with a user about the visibility of game servers on a large network. The old
multicast algorithm was de-facto randomized due to its distributed nature, while
the new algorithm is more deterministic. This will restore some randomization
beyond limit-overflow conditions.
It won't affect small networks at all.
ZeroTier 1.0.0 brings a number of under the hood improvements and bug
fixes. These include but are not limited to:
* A simpler, faster multicast algorithm that places full burden
for multicast propagation on the sender. This results in better
fairness without CPU-intensive signature/verify on every packet,
lower latency for intra-data-center SDN operations, and avoids
distributed burdens that are intrinsically unfriendly to mobile
clients subject to wake frequency limits and battery life
constraints. In the future this may be augmented to allow
optimized delivery to multiple recipients at the same site via
federation.
* Significant code reorg to move toward mobile support (iOS, Android)
and future SDK packaging.
* A number of efficiency and stability improvements.
* Bug fixes for Linux and ARM users.
* Improved NAT traversal, including limited support for port
numbering scheme guessing to traverse some symmetric NATs.
Upgrade from 0.9.x is not required but is strongly recommended. Older
clients using the old multicast algorithm are presently supported via
legacy hooks, and these may go away at some point in the future. We'll
monitor the status of the network and try to keep legacy support around
as long as people need it, but it'll probably be pulled once 95%+ of
clients are 1.0.0 or newer.
The next versions will bring further bug fixes, improved user experience,
more enterprise-grade features for intra-data-center use, and more!
