#####System

None

####Enhancements

These changes are to improvements to existing features (which includes changed default values):

#####UI

Allow user to specify (the log of) the number of rows per chunk for a new constant chunk; use this new function in CreateFrame (github)

Add row and column count to H2OFrame show method (github)
Admin watermeter page (PUBDEV-234)
Admin stack trace (PUBDEV-228)
Admin profile (PUBDEV-227)

Need shutdown, minimally like h2o (PUBDEV-74)

#####API

Changed 2 to 3 for JSON requests (github)
Rename some more fields per consistency (max_iters changed to max_iterations, _iters to _iterations, _ncats to _categorical_column_count, _centersraw to centers_raw, _avgwithinss to avg_within_ss, _withinmse to within_mse) (github)
Changed K-Means output parameters (withinmse to within_mse, avgss to avg_ss, avgbetweenss to avg_between_ss) (github)
Remove default field values from DeepLearning parameters schema, since they come from the backing class (github)
Add @API help annotation strings to JSON model output (PUBDEV-216)

#####Algorithms

Minor fix in rapids matrix multiplicaton (github)
Updated sparse chunk to cut off binary search for prefix/suffix zeros (github)

Fix model parameters' default values in the metadata (github)
Set default value of k = number of clusters to 1 for K-Means (PUBDEV-251)

#####System

Reject any training data with non-numeric values from KMeans model building (github)

####Bug Fixes

These changes are to resolve incorrect software behavior:

#####UI

None

#####API

Fixed isSparse call for constant chunks (github)
Fixed sparse interface of constant chunks (no nonzero if const 1= 0) (github)

#####Algorithms

None

#####System

Typeahead for folder contents apparently requires trailing "/" (github)
Fix build and instructions for R install.packages() style of installation; Note we only support source installs now (github)
