Frequently Asked Questions

My Unison 1 serial number doesn't work for Unison 2!

As Unison 2 is a major update from Unison 1, we've made it a paid upgrade to ensure we can continue to work on it. On the plus side, you can use your Unison 1 serial number to get an upgrade discount right here.

How come I can't mark files as "read" anymore?

While you can't mark binary content as "read," you can now "delete" files you don't want to see anymore. This will prevent them from loading again, and also helps keep the cache databases manageable, making Unison run even faster. That said, we're still considering the issue!

How can I use SSL with Unison Access?

Set your server to news-ssl.panic.com. (Or, if in Europe, news-ssl.europe.panic.com, fancypants.)

Which ports are available for Unison Access?

If the default ports aren't working for you, you can try ports 443 or 8080. For the SSL-enabled servers, try ports 80 and 81 instead.

I can't run the new Unison.

That's not a question, but if you really want to shun progress and live in the past (it's OK with us!), check out the Panic Museum. Or just download Unison 1.8.1.
