spatialwarnings v3.1.1 (Release date: unknown)
==============================================

This is a minor release to make tests compatible with an upcoming release of ggplot2.

Bug fixes and misc changes:

  * New bounds added to the parameters of variogram fits to improve convergence

  * Tests are now shorter on CRAN machines

spatialwarnings v3.1.0 (Release date: 2024-09-06)
=================================================

This release has received external contributions from K. Siteur

Improvements: 
  
  * The type of neighborhood can now be specified in all patch-related functions, 
      including high-level functions (e.g. `patchdistr_sews`). Neighborhood can also be 
      specified using the strings "von_neumann" or "moore", on top of a 3x3 matrix
  
New indicators: 
  
  * Clustering of pairs (e.g. Schneider et al. 2016)
  
  * Indicators related to the LSW distribution (Siteur et al. 2023)

Bug fixes and misc changes: 
  
  * Many documentation improvements and minor fixes 
  
  * Old defunct functions have been removed

spatialwarnings v3.0.3 (Release date: 2022-03-21)
=================================================
  
This release has received external contributions from J. Guerber.

Improvements: 

  * In patch size distribution plots, fits are now rescaled when xmin is above 1 
      so they overlay nicely on the observed distribution
  
  * Better handling of errors in segmented::segmented() when fitting variograms 
  
Bug fixes: 
  
  * Fixed an error occurring when using xmin = "estimate" in patchdistr_sews
  
  * Remove calls to assert() that were leftover from testing (CRAN policy)
  
spatialwarnings v3.0.2 (Release date: 2021-12-16)
=================================================
  
Improvements: 
  
  * Matrix attributes are now preserved when generating null matrices (except 
      when shuffling the original matrix, null_method = 'perm')
  
Bug fixes: 
  
  * Computation of Moran's I is now accurate for small matrices
  
spatialwarnings v3.0.0 (Release date: 2021-05-19) 
=================================================

Improvements: 

  * Documentation extended and improved
  
  * Fitting of distributions now uses 'plexpo' and 'trunc' to refer to the 
      exponent of a power-law ("slope") and its exponential truncation (from 
      "expo" and "rate", which were ambiguous)
  
  * EXPERIMENTAL: Variogram-based indicators have been added. Note that this 
      deserves more testing and application to real-world data to make sure that
      the computation of variograms are accurate enough. 
  
  * EXPERIMENTAL: Significance of flow length can now be assessed using the 
      analytical approximation described in Rodriguez et al. (2017)
  
Bug fixes: 
  
  * Fixed a bug where available methods were not displayed in `summary()`
  
  * Fixed a bug where the r-spectrum was wrong when the matrix had an odd number 
      of rows or columns
  
Misc changes: 
  
  * NAs in provided matrices now produce warnings instead of errors
  
  * Dependency to tidyr has been removed (this fixes occasional NOTEs on CRAN
     automated checking)
  
Removals: 

  * All deprecated functions in spatialwarnings v2.0.0 are now defunct
  
spatialwarnings v2.0.0 (Release date: 2020-05-14)
=================================================

Improvements: 
  
  * New methods are available to produce null matrices, on top of shuffling the
      original matrix (e.g. based on smoothing the original matrix). 
  
  * Significance of Power-law range can now be tested using `indictest()`. 
      Using `plot_distr()` on the resulting objects will display the 0.05/0.95 
      quantiles of the null patch size distributions. 
  
  * The package gains a generic function `display_matrix`, to eyeball the  
      matrices being used in `spatialwarnings` objects using ggplot2
  
  * Improved the fitting of distributions, which should be more robust now. 
  
  * Speed improvements in label()
  
Bug fixes: 
  
  * Fixed a bug where the normalization constant for truncated power-laws was 
      miscalculated
  
Removals: 
  
  * All the deprecated `*_spews` functions are now defunct (removed). 
  
  * Most `indicator_*` functions are now deprecated. 
  
Misc changes: 
  
  * Lots of duplicated code has been removed
  
  * Minor changes in print/summary methods
  
  * The FAQ has been expanded and improved. See the following page: 
      https://alex.lecairn.org/spatialwarnings-faq.html
  
  * Dependency to VGAM is now removed 
  
spatialwarnings v1.3.1 (Release date: 2018-12)
==============================================

New indicators:
  
  * Planar flowlength (Mayor et al. 2013, Rodriguez et al. 2017)
  
  * Kolmogorov complexity based on Block Decomposition Method
      (Dakos and Soler-Toscano 2016)

Improvements:

  * Enable parallel computation of patch size distributions
  
  * Added a dataset of aerial view of vegetation in Arizona ('arizona')
  
  * Added functions to compute the coarse-grained variance/skewness on a
      single matrix

Bug fixes and code improvements:

  * Added missing methods exports for custom indicators
  
  * Fixed the patch labelling for non-square images
  
  * General code cleanup and improvement

Documentation and description changes:

  * Updated references to reflect the publication of new paper presenting
      the package <doi:10.1111/2041-210X.13058>
