Date Tue, 14 Jun 2016 07:39:04 GMT

the sub-bullet "c - fixes backwards compatibility MRv1" also referred to
(1) guava dependency conflicts (for MRv1, the classpath has a very old
version), and (2) a couple of runtime changes such as SYSTEMML-513 (task
handling for multiple output committer which overwrites the default file
output committer).

ok, here is a first draft of the release notes - please feel free to
extend or prune this:

a) [SYSTEMML-377] Different internal implementation types of spark matrix
* Supported internal formats: MCSR (default), CSR, COO
* Automatic MCSR->CSR on Spark read/caching (for memory efficiency)
* Automatic MCSR->CSR on sparse update-in-place (avoid serialization)

b) [SYSTEMML-554] Enhanced SystemML Frame support for JMLC API / CP
* SystemML frame data type, deeply integrated into compiler and runtime
* New builtin functions: transform, transformapply, transformencode,
transformdecode, transformmeta
* Supported operations: read/write, left/right indexing, casting, append,

c) Framework compatibility / configuration
* [SYSTEMML-418] Version-specific Spark memory budgets (>=1.6, legacy)
* [SYSTEMML-158] Updated deprecated Hadoop properties
* [SYSTEMML-476] Version-specific MR configuration handling (MRv2, MRv1)
* Fixes for backwards compatibility to MRv1 (?? shouldn't this be in -158
* New pass-through mapred/mapreduce configurations through SystemML-config
* [SYSTEMML-584/585] New thread-local configuration handling (compiler/dml

d) Deep learning support (experimental)
* [SYSTMEML-618] New DML-bodied function library for deep learning
* [SYSTEMML-540] New builtin singlenode operations: conv2d, maxpooling,

imports, absolute paths)
* [SYSTEMML-617/631/654] Improved name space handling
* [SYSTEMML-240] Extended stats outputs for Spark
* [SYSTEMML-495] SystemML configuration handling

f) New fused physical operators
* [SYSTEMML-488] Fused wdivmm w/ 4 operands
* [SYSTEMML-510] Fused wdivmm/wcemm w/ eps term

g) Various performance features

* [SYSTEMML-282] Extended update-in-place support for parfor intermediates

* [SYSTEMML-552/399] Performance parallel binary/text readers (sort
sparse/nnz handling)
* [SYSTEMML-552/641] Cache-conscious operations: sparse-dense
wdivmm/wsloss, sparse-dense/sparse-sparse mm, dense-dense skinny rhs mm
* [SYSTEMML-641] Tuned special cases for block matrix multiplication:
e.g., mm w/ skinny rhs, colwise parallelization wide rhs
* [SYSTEMML-396/400] New/extended multithreaded operations:
cumsum/cummin/cummax/cumprod, transpose, and rand
* [SYSTEMML-510/694] New simplification rewrites: "pushdown
