+1, with comments:

There are 5 critical issues for 2.4, and no blockers:
SPARK-25378 ArrayData.toArray(StringType) assume UTF8String in 2.4
SPARK-25325 ML, Graph 2.4 QA: Update user guide for new features & APIs
SPARK-25319 Spark MLlib, GraphX 2.4 QA umbrella
SPARK-25326 ML, Graph 2.4 QA: Programming guide update and migration guide
SPARK-25323 ML 2.4 QA: API: Python API coverage

Xiangrui, is SPARK-25378 important enough we need to get it into 2.4?

I found two issues resolved for 2.4.1 that got into this RC, so marked
them as resolved in 2.4.0.

I checked the licenses and notice and they look correct now in source
and binary builds.

The 2.12 artifacts are as I'd expect.

I ran all tests for 2.11 and 2.12 and they pass with -Pyarn
-Pkubernetes -Pmesos -Phive -Phadoop-2.7 -Pscala-2.12.
