good news. i'm a bit late to the game with my libraries, but i'm trying to publish them now. i have a few dependencies for which no RC2 builds exists (e.g. scopt) -- is RC2 binary compatible to RC1?
best, .hh.

Yes, scopt 2.1.0 for 2.10.0-RC2 was pushed to sonatype last night (also late to the game). In a while it should also be available from maven central too.

Starting to check out my projects on 2.10.0-RC2 and the following is trimmed from code in Scala Migrations where 2.10 has different behavior:
sealed trait ColumnOption case object NotNull extends ColumnOption case object PrimaryKey extends ColumnOption
object test { def main(args: Array[String]) { val l = List(PrimaryKey, NotNull) for (option @ NotNull <- l) println("Found " + option) }
}
$ for f in 2.7 2.8 2.9 2.10; do echo $f; scalac-$f t.scala && scala-$f test; done 2.7 Found NotNull 2.8 Found NotNull 2.9 Found NotNull 2.10 scala.MatchError: PrimaryKey (of class PrimaryKey$) at test$$anonfun$main$1.apply(t.scala:9) at test$$anonfun$main$1.apply(t.scala:9) at scala.collection.immutable.List.foreach(List.scala:309) at test$.main(t.scala:9) at test.main(t.scala)
Removing the "option @" and not using the "option" symbol:
for (NotNull <- l) println("Found " + NotNull)
then gets it to compile, but NotNull now shadows the case object, generating output:
2.7 Found PrimaryKey Found NotNull 2.8 Found PrimaryKey Found NotNull 2.9 Found PrimaryKey Found NotNull 2.10 Found PrimaryKey Found NotNull
So this isn't obvious that naming the iterator value with @ would change the behavior. Compared to this, neither the old nor new behavior seems to make sense, but which one is more correct? I took the <- here to implicitly filter on the type of objects coming from the list.

IMHO, it is a bug. Pattern match on for comprehension works slightly
different than normal pattern matching, which makes 2.10 behavior incorrect.

How does one get pre-notified of a new RC release to build ones packages to be included in the next announcement email? A description to use for the next announcement: "Database migrations written in a Scala DSL."

See Adriaan's email yesterday on scala-internals about RC3 being staged.
