Hi.


I think we are very close to releasing 3.3.
Looking through the issues, the following should/need to be resolved:

[...]

 * [MATH-923] Kohonen's SOFM: can it be considered finished?

Done.

 * [MATH-928] Alternative approach to matrix implementations:

   postpone to 4.0?

Done.


 * [MATH-990] Improve performance of MathArrays.sortInPlace:

   finished for 3.3?

Done.



Other issues to be discussed:

 * [MATH-1008]

   a new package has been created o.a.c.m.fitting.leastsquares which
   contains some interface for the new fluent API but they are also
used elsewhere so I guess it would be more logical to put them in a
   more general place, e.g. WithMaxEvaluations should be moved to
   o.a.c.m.optim. WDYT?

Strictly speaking, these have potential use outside the "o.a.c.m.optim"
package.

Also, further improvements were postponed since the alternate proposal
looked quite promising:
  https://issues.apache.org/jira/browse/MATH-1026

[...]
