This more a bug fix than a new feature, I wouldn't put it in the highlight.

+We introduces a new form of types called match types. A match type reduces to one of a number of

I would use the past tense: "We've introduced". Also we should note that this feature is still experimental and subject to changes.

+### Name-based `unapplySeq` is now supported
+
+Similarly to the `unapply` method, an extractor object can now define a `def unapplySeq(x: T): U`


I would note that this matches what Scala 2.13.0-M5 does, and add a link to http://dotty.epfl.ch/docs/reference/changed/pattern-matching.html

+
+Dotty 0.10.0-RC1 requires sbt 1.2.3 and sbt-dotty 0.2.4.


maybe "1.2.3 or newer", since 1.2.4 is released

I would actually advise against using 1.2.4 because of https://gitter.im/sbt/sbt?at=5bbbbcea6e5a401c2d39580f

+
+Using sbt 1.1.5 or newer, do:


"1.2.3 or newer" here, too

here we're actually talking about the minimal version of sbt where you can use "sbt new" and have things work correctly I think.

Okay, but if the post uses two different version numbers like this, even if it's technically justifiable, I think other readers will, like me, 1) be confused, 2) assume it was probably a mistake
