Major Changes
* Mac version no longer requires a kernel extension, instead making use of the [feth interfaces](https://apple.stackexc
* Added support for concurrent multipath (multiple paths at once) with traffic weighting by link quality and faster rec
* Added under-the-hood support for QoS (not yet exposed) that will eventually be configurable via our rules engine.
Minor Changes and Bug Fixes
* Experimental DB driver for [LF](https://github.com/zerotier/lf) to store network controller data (LFDB.cpp / LFDB.hpp
* Modified credential push and direct path push timings and algorithms to somewhat reduce "chattiness" of the protocol
* Removed our beta/half-baked integration of Central with the Windows UI. We're going to do a whole new UI of some kind
* Fixed stack overflow issues on Linux versions using musl libc.
* Fixed some alignment problems reported on ARM and ARM64, but some reports we could not reproduce so please report any
* Fixed numerous other small issues and bugs such as ARM alignment issues causing crashes on some devices.
* Windows now sets the adapter name such that it is consistent in both the Windows UI and command line utilities.
* Fixed a bug that caused exits to take a long time on Mac due to huge numbers of redundant attempts to delete managed routes.
* Fixed a socket limit problem on Windows that caused the ZeroTier service to run out of sockets, causing the UI and CLI to be unable to access the API.
* Fixed a threading bug in the ZeroTier Core, albeit one that never manifested on the regular ZeroTier One service/client.
* Fixed a bug that could cause the service to crash if an authorized local client accessed an invalid URL via the control API. (Not exploitable since you needed admin access anyway.)
