Dotty is apparently the "next generation compiler for Scala": http://dotty.epfl.ch/
It's being developed separately from Scala 2. For example, it interops with 2.11 but not 2.12.
This is some language; not the graph layout package.
It's the new language that the creator of Scala is now working on.
On a different note: I've noticed that HN is starting by to develop the drive-by-I-disagree-voting that Reddit has. That's unfortunate.

I've never heard of dotty-the-language before this morning, but have been a long-time dotty user. I was hoping to help antialias the name collision for others. On a different note: I've noticed that HN is starting by to develop the drive-by-I-disagree-voting that Reddit has. That's unfortunate.

I'm sure you meant well, but the way you phrased your post made it sound more dismissive about something you didn't care about than helpful. I think that's a far more likely explanation for the downvotes than "HN becoming more like Reddit".

It's a brand new language that looks like Scala but has its own syntax, which is incompatible with Scala's.
That's no true at all. The syntax is pretty similar with few key differences. The idea is for dotty to become Scala 3.0. But, in the meantime, the next Scala 2.* versions will pave the way for 3.0. Meaning to avoid too many breaking changes in 3.0. The above has been said repeatedly by Martin Odersky (creator of Scala) and the folks on the Scala compiler team in talks and discussions.

Yes. It's essentially Scala 3 (though that is a rather foreboding, Python 3 like name). It's being developed separately from Scala 2. For example, it interops with 2.11 but not 2.12.
The Scala 2.12 compiler will soon compile the Scala 3 compiler [1]

No, Dotty is the next generation Scala compiler, the syntax is overwhelmingly compatible, with new features and some breakage. Just like Go has "gofix", Scala will have "Scalafix", that will automate migration between Scala 2.x (scalac) and Scala 3.x (Dotty)
"Tricky" as in [2] "Spark 1.x's Dataset API runs into subtle source incompatibility problems for Java 8 and Scala 2.12"

Martin has made no guarantee of compatibility or even to supply a Scalafix app. The fact you can do this relatively easily today is just a consequence of Dotty being very young. As it evolves and becomes more complex, there is no guarantee that a translation from Scala to Dotty will even be possible to achieve automatically.
The entire point of scalafix[1](developed by the Scala Center) is to bridge the gap between Scala 2.x and Scala 3/Dotty. Martin talks about it in every Dotty presentation.
I like to take a look at /compiler/src/dotty/tools/dotc to whet my appetite from time to time [2].
