Scala 2.8.1 RC4 - details

Hello everyone,

As you will have noticed by now, a new 2.8.1.RC4 is out. We had to issue
this additional release candidate due to a regression that was pointed out
to us during the testing window. The bug was found in these two tickets:

#3939 - Scala compiler rejects override of abstract protected Java
#3947 - Can't override protected Java member from outer package

The underlying problem was the same for both, and has now been fixed in
RC4. In addition, a serious glitch was found in Scaladoc that was
preventing the search box from operating normally; that has also been fixed.

No other changes were made, as we are really striving to keep a stable code
base, in order to push the final out as soon as feasible.

Please do test this new version, and let us know if you find any further
regressions during the coming week. The plan is to publish the final 2.8.1
version right afterwards.

Thanks!
Toni
