Changes in version 1.6 (2023-03-13)                   

New set of functions for distance-decay models:

  - decay.model() now allows fitting the Gompertz function (as described
    in Martín-Devasa et al. 2022, Diversity and Distributions), in
    addition to negative exponential and power law functions. To do
    this, nonlinear models are now fitted via the nls.lm() function in
    the minpack.lm package (which uses the Levenberg-Marquardt Nonlinear
    Least-Squares Algorithm), instead of glm() as in the previous
    versions of betapart

  - boot.coefs.decay() now implements the site-block resampling method
    introduced in Martínez-Santalla et al. 2022 (J. Biogeogr.)

  - A new function, zdep() allows assessing the significance of
    differences between parameters of two distance-decay models, as
    introduced in Martín-Devasa et al. 2022 (Ecol. Informatics)

  - plot.decay() was modified to handle the new decay.model() function

                 Changes in version 1.5.6 (2022-04-06)                  

  - Modified function decay.model() to implement the block permutation
    described in Martínez-Santalla et al 2022 (J. Biogeogr.) for
    assessing the significance of the distance decay model

                 Changes in version 1.5.5 (2022-03-24)                  

  - A bug of functional.betapart.core() was fixed to run it in parallel
    with multi = TRUE

                 Changes in version 1.5.4 (2021-04-11)                  

  - Updated functional.betapart.core.pairwise() to get vertice
    coordinates in the output details

                 Changes in version 1.5.3 (2021-03-05)                  

The libraries doParallel/parallel were replaced by doSNOW/snow for parallel computations.

  - functional.betapart.core() was updated. Options can be passed to
    qhull to prevent some crashes and a progress bar can be displayed.
    When setting multi=TRUE, the function stop earlier if the number of
    communities is too important.

  - New function to control options passed to qhull for convexhull
    estimation: qhull.opt()

  - New function to compute rapidly pair-wise dissimilarty matrices:
    functional.betapart.core.pairwise()

  - functional.beta.pair() was updated to integrate
    functional.betapart.core.pairwise

                 Changes in version 1.5.2 (2020-09-09)                  

New features:

  - Updated functional.betapart.core() to allow internal parallel
    computing
  - New function to customize parameters for the internal parallel
    computing : beta.para.control()

                 Changes in version 1.5.1 (2018-10-18)                  

New features:

  - Updated functional.betapart.core() to allow parallel computing

                 Changes in version 1.5.0 (2018-02-22)                  

New functions to fit, plot and bootstrap distance-decay patterns

  - decay.model() fits a negative-exponential or mower law function
    describing the decay of assemblage similarity with spatial distance.

  - plot.decay() allows plotting the curves fitted with decay.model().

  - boot.coefs.decay() bootstraps the parameters of the functions fitted
    with decay.model().
