Changes in version 2.0.1                        

INTERNAL CHANGES

  - tests with testthat moved to correct location

                 Changes in version 2.0.0 (2016-08-16)                  

DOCUMENTATION

  - demos revamped

INTERNAL CHANGES

  - rewritten core functions, simplified interface

  - the theory is now more accurately described and properly implemented

USER-LEVEL CHANGES

  - clusters are now defined with column-major conventions

  - new clusters and functions for dye layers (but no core yet)

                 Changes in version 1.5.1 (2014-01-19)                  

INTERNAL CHANGES

  - use symmetry to calculate only half of the off-diagonal interaction
    matrix blocks

  - tweak LinkingTo Rcpp for CRAN

                  Changes in version 1.5 (2013-11-27)                   

INTERNAL CHANGES

  - complete rewrite of the internal functions to clean up and optimise
    the passing of parameters

  - cross-sections are now calculated for multiple incident angles at
    once

  - corrected a missing factor of 1/sqrt2 in dispersion calculation with
    circular polarisation

  - Rcpp::function tweaks to please c++11 and clang for CRAN release

  - more complete internal tests based on testthat (see inst/tests)

  - (non-exported) standalone R version of the core CDA functions for
    testing and debugging

USER VISIBLE CHANGES:

  - dispersion_spectrum now calculates extinction, absorption and
    scattering

  - the linear system is now always solved with a (multiple) right-hand
    side (incident fields), the option to invert the matrix has been
    removed. It was slower in most cases anyway

  - linear_extinction_spectrum no longer exists. Use the more versatile
    dispersion_spectrum instead

  - demos updated to reflect the internal changes

                         Changes in version 1.4                         

USER VISIBLE CHANGES:

  - QMC angular averaging gains an 'iterative' routine, adding new
    integration points until specified accuracy is reached

  - a 'cheap' (fast) version of angular averaging is added, only using 3
    angles but providing in most cases a good estimate of full averaging

BUG FIX:

  - Armadillo 0.190 brought some changes that made the results incorrect
    at the C++ level. First, the diagonal part of the interaction matrix
    was filling the off-diagonal blocks with non-zero elements due to
    non-initialisation of the matrix. Second, the integer flag for the
    Axes (x, y, z) was passed as a arma::uvec, where arma::ivec should
    be used.

                 Changes in version 1.3.3 (2013-06-23)                  

  - CRAN update

  - submitting more complete copyright information at the request of
    CRAN maintainers, to explicitly state the copyright of LAPACK
    routine src/zgels.f

                        Changes in version 1.3.1                        

INTERNAL CHANGES:

  - depends on dielectric 0.2.2

                  Changes in version 1.3 (2012-11-28)                   

INTERNAL CHANGES:

  - fixed polarisation and orientation issues in dispersion calculations

  - cleaned up internal code

  - started using testthat for consistency checks in future releases

USER VISIBLE CHANGES:

  - function names have changed to be more consistent

  - all dimensions are now in nanometres

  - updated the licence to GPL3 + LICENCE file

DOCUMENTATION:

  - new examples under inst/wiki formatted for knitr+markdown and
    updating the github wiki

  - cleaning up demos, examples and vignettes

  - link to github + wiki as the source of documentation

                  Changes in version 1.2 (2012-08-08)                   

INTERNAL CHANGES:

  - explicit export of functions

  - theme_minimal adapted for ggplot2

NEW FUNCTIONALITY:

  - dispersion_spectrum() calculates the optical response as a function
    of incident angles and wavelength, for two orthogonal linear
    polarisation states

                 Changes in version 1.1.3 (2012-03-05)                  

  - fixed bugs for ggplot2-0.9.0

                 Changes in version 1.1.2 (2011-12-20)                  

  - fixed implicit conversion of sqrt(2) to sqrt(2.0) for Solaris
  - fixed .onLoad function

                 Changes in version 1.1.1 (2011-09-04)                  

                         Changes in version 1.1                         

USER-VISIBLE CHANGES:

  - New dependency on randtoolbox (Halton sequences for Quasi-Monte
    Carlo angular averaging.

ENHANCEMENTS:

  - Choice of three methods for angular averaging: regular grid, Gauss
    Legendre Quadrature, Quasi-Monte Carlo (default). N now refers to
    the number of integration points (GL may use a slightly higher
    number of points, rounded as ceiling[sqrt(N)]).

  - added tests/ subdirectory, featuring numerical tests of consistency.

BUG FIXES:

  - Removed Encoding: UTF-8 from Description

                  Changes in version 1.0 (2011-07-25)                   

Initial CRAN release.
