0.3.2.x alpha releases of Tor support version 3 of the Tor Rendezvous Specification (onion services protocol):
We are hyped to present the next generation of onion services! We've been working on this project non-stop for the past 4 years and we officially launched it two weeks ago by publishing our first alpha releases.
The new addresses will be longer and harder to discover:
The Tor team has been working on the new onion technology for the past four years, which aims to increase the anonymity level for onion services. In the legacy onion system the network itself could be leveraged to learn about the onion addresses that were using it.
With the new onion system, the onion services are completely private. Only you, the owner of the onion, and those to whom you will disclose the address, will know about your onion service' address. Nobody outside of their tight private groups could discover certain onion addresses, unless one of the group members disclosed it to others.
Websites such as Facebook, ProPublica, and The New York Times will likely want their address to be known to the whole public, so this benefit will not apply to them.
The legacy addresses will continue to be supported for years, depending on how fast the community adopts the new addresses.

Legacy addresses will be supported for years.
Your willingness to write down super long v3 addresses will be proportional to your desire for anonymous services. You could also use less secure methods of sharing them, such as passing around a USB drive or taking a picture of a poster with the address on it (QR code with .onion address?).
