b) [SYSTEMML-554] Frame support for JMLC API / CP
  * New frame data type, deeply integrated into compiler and runtime
  * New builtin functions: transformapply, transformencode,

  * Fixes for backwards compatibility to MRv1
  * New pass-through mapred/mapreduce configurations through
SystemML-config
  * [SYSTEMML-584/585] New thread-local configuration handling

Subject:	Release notes for 0.10.0



Hi,

We need to put together a page of release notes for the 0.10.0 release
(similar to http://systemml.apache.org/0.9.0-incubating/release_notes.html
).
Could SystemML committers and contributors please respond to this thread
with what they feel are the major updates/improvements in this release?

Thanks!
Deron
