[David Hall]

I guess we're on a yearly release schedule now.

I'm pleased to announce the release of Breeze 0.13. This is the first release that supports Scala 2.12. 2.11 and 2.10 continue to be supported.

Changes:

* Scala 2.12 support (YuIzawa)

* ODE Solver Suite (Jake Timothy)

* Quasi-Monte Carlo via Halton Sequences (Stucchio)

* new functions: digitize, bincount, relu (Chris Stucchio, Carsten Schnober)

* chi^2 hypothesis test (Stucchio)

* Support for BigDecimal in DenseMatrix etc (dlwh)

* file"..." interpolator for more ergonomic file creation (Oleksii Tkachuk)

* DM.reshape can only produce views of column-major matrices (dlwh)

* Lots of various build improvements (dlwh, Fokko Driesprong, qilab, Yusuke Izawa)

* Improvements/fixes to distributions/random (Chris Stucchio, Vaishaal Shankar, Sergey Kokorin, brendon,  Paul Kernfeld, Darren Wilkinson,  Tomasz Sobieszek)

* median now works on scala.Seq (Vishal Kuo)

* Rand.withSeed to allow for repeatable rand instances (Alex Gaudio)

* added asserts for mismatched vector lengths (Alex Gaudio)

* Allow creation of empty literal DenseMatrices (Benjamin Fisher)

* bug in transposing empty DenseMatrix (Mateusz Kapturski)

* improved slicing for DenseMatrix, SliceMatrix (Michael Petnuch, dlwh)

* improved consistency about Transpose for row vectors (Michael Petnuch)

* dramatically improve dot product for Counters (dlwh)

* fix stupid bug in DiffFunction.withL2Regularization

* improved Beam interface to be more Scalactic...

* serialization fixes, SerializedForms for a variety of core classes (adpauls, dlwh)

* fixed bug in argtopk (Yanbo Liang)

* fixed bug in BroadcastedRows for DenseMatrix (torsten schmits)

* improved shuffle (Huamin Li)

* fix rsquared ( Lucas Fernandes Brunialti)

* fix doc for cosineDistance (Zak Patterson)

* perf improvement to BitVector.mapActivePairs (dlwh)

Hi David,

There seems to be a newer release 0.13.1 on github. Is there any release notes for that version? 

Thanks.

[David Hall]

I guess I never put together release notes. It's mostly small things, with the exception being your(? sorry, not sure if you are weichen xu) fix for lbfgsb's line search, which was pretty broken. Otherwise, there are:

* better edge case handling for Gaussian.probabilityOf

* logit function

* misc cleanups

* perf improvement to DenseVector.tabulate

* make VectorBuilder respect initialNonZero

The main reason it was cut for was the lbfgsb fix
