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 
blocks 
* 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, 
transform/transformapply

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 
config) 

d) Deep learning support (experimental)
* [SYSTMEML-618] New DML-bodied function library for deep learning
* [SYSTEMML-540] New builtin singlenode operations: conv2d, maxpooling, 
im2col, col2im, rotate 
* New lenet-train DML script (staging)

e) API/script usability
* [SYSTEMML-607/604/611] Parser error handling
* [SYSTEMML-506/508/544/577/649/651] Extended MLContext/JMLC APIs 
* [SYSTEMML-625/626/632] Improved source statement handling (e.g., 
imports, absolute paths)
* [SYSTEMML-617/631/654] Improved name space handling
* [SYSTEMML-240] Extended stats outputs for Spark 
collect/broadcast/parallelize
* [SYSTEMML-495] SystemML configuration handling
* [SYSTEMML-209] Include algorithms in systemml jar
* [SYSTEMML-647/648] Deprecated castAsScalar, ppred
* [SYSTEMML-477] JSON meta data handling
* [SYSTEMML-294] Print matrix builtin function
* [SYSTEMML-296/676/670] Improved PyDML syntax: slicing, rand, cdf, elif
* [SYSTEMML-675] Support for negative for/parfor loop increments

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-427/512] Extended IPA (propagate scalar variables)
* [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 
unaryagg-transpose", "simplify transpose-aggbin-binary chains", "reorder 
minus-mmult", "canonicalize matmult-add-scalar", improved constant folding 
(all unary) 
* [SYSTEMML-653] Asynchronous bufferpool cleanup of evicted files / nio 
file eviction
- MR iqm/quantile/median (qsort num reducers, qpick buffer size)

h) DML script updates
* [SYSTEMML-536] New KNN algorithm (still staging) 
* [SYSTEMML-534] Optional console output univariate statistics
* [SYSTMEML-494] GLM compiler warnings

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
