------------------------------------------------------------------------
TMB 1.6.0 (2015-10-08)
------------------------------------------------------------------------

o Major changeset to get closer to CRAN submission

  - Added 'dontrun' to most examples. Reason: All useful TMB examples
  take too long time to run because they require compilation.

  - Removed TMB-internals.

  - Added Roxygen for remaining functions: dynlib()
  runSymbolicAnalysis() config() plot.parallelBenchmark()
  summary.sdreport() print.sdreport() print.backtrace()
  plot.tmbprofile() confint.tmbprofile()

  - Got rid of global configuration, e.g flagsDefaults(),
  newtonDefaults() etc.

  - Reworked newtonOption() and adapted all examples to new syntax.
  (NOTE: not entirely backwards compatible since to old version
  modified global settings, which we do not allow anymore).

  - Fixed several typos, e.g. c++ -> C++

  - CITATION: Added arxiv reference.

  - DESCRIPTION: Changed title and added URL.

  - NAMESPACE: Cleanup

o CppAD jacobian: prefer reverse mode over forward mode if work is equal
  - TMB only requires 1st order reverse (not forward) mode to be
  implemented for atomic functions. This can result in the error
  'order not implemented' if CppAD automatically selects forward over
  reverse mode.
  - In cases where the work of forward and reverse mode are equal it
  is therefore more natural (from TMB perspective) to select reverse
  mode.

o Document parallel_accumulator #122

o Lots of doxygen documentation updates

------------------------------------------------------------------------
TMB 1.5-1 (2015-10-04)
------------------------------------------------------------------------

o Experimental oneStepPredict() now handles discrete case as part of a
  general 'oneStepGeneric' method.

o tmbprofile() multiple changes
  - Allow specification of a valid range of the parameter.
  - Get more detail in the center of the distribution.
    (does not affect cases where likelihood has been optimized)

o C++: New namespace 'autodiff' makes it easy to use AD from the user
  template.

o C++: New namespace 'romberg' with wrappers around CppAD integration
  routines.

o Automatic retape when loading saved ADFun objects.

o Fix 32 bit

o match pattern: Improvement for large problems. As a result it is now
  be possible to handle 2^31-1 nonzeros in Cholesky factor. Old method
  would break down around 2^30.

o oneStepPredict() now works with maps #108.

  component (not just the re-mapped univariate index).

o BesselK atomic + Matern correlation function.

  should not drop zero-entries that could potentially become nonzero
  (i.e. parameter dependent entries).

o New experimental function 'oneStepPredict' for OSA residuals with
  ar1xar1 as an example.

o New example: HMM filter.

o General 1D likelihood profile function + method to get profile
  confidence intervals + plot method.

  without loosing the ML interpretation).
