Arti 1.1.7 is released: incremental improvements, numerous bugfixes

Arti is our ongoing project to create a next-generation Tor client in Rust. Now we're announcing the latest release, Arti 1.1.7.

This focuses on maintenance, bugfixing, and cleanups to earlier releases. It also lays groundwork for being able to run as an onion service.

Notable bugs fixed include one that prevented Arti from being able to connect to certain onionbalance onion services, one where we didn't compile in support for connecting to onion services by default, and one that broke bridge connections under some circumstances.

We've also added initial implementations of the HashX ASIC-resistant hash function and the related EquiX proof-of-work function, for eventual use in protecting onion services from denial-of-service attacks.

With this release, there have been many smaller and less visible changes as well; for those, please see the CHANGELOG.

For more information on using Arti, see our top-level README, and the documentation for the arti binary.

Thanks to everybody who's contributed to this release, including Alexander Færøy, Dimitris Apostolou, Jim Newsome, juga, Kunal Mehta, Micah Elizabeth Scott, Saksham Mittal, sw1tch, and Trinity Pointard.

Also, our deep thanks to Zcash Community Grants and our other sponsors for funding the development of Arti!
