                 Changes in version 0.1.3 (2025-09-23)                  

This release represents the version used to generate all benchmark
results and figures reported in the forthcoming manuscript.

Improvements

  - Performance optimizations.
  - Refined core routines for faster runtime in typical benchmark
    scenarios.
  - Vignettes: explicit graphics-state resets per CRAN guidance:
      - Save and restore par() with oldpar <- par(no.readonly = TRUE);
        par(oldpar) around changes.
      - Reset layout() with layout(1) when used.

                        Changes in version 0.1.2                        

  - Fix: NA-semantic parity with terra::focal() under na.rm=TRUE/FALSE
    and na.policy="omit"; removed speckle artifacts at NA boundaries.
  - Fix: Correct matrix orientation and final transpose in FFT path.
  - Perf: Auto-padding to next 5-smooth lengths (2*3*5 factors) to avoid
    large-prime slowdowns in FFTs.
  - Rebuilt vignettes and refreshed documentation.
  - Fixed Rd markup (e.g., replaced {terra} with \pkg{terra}).
  - Removed non-ASCII characters from R sources and roxygen; math now
    uses Rd math (e.g., \eqn{\sigma}).
  - Vignettes now restore user graphics state:
      - Added oldpar <- par(no.readonly = TRUE); on.exit(par(oldpar),
        add = TRUE) in chunks that modify par(...).
      - Added on.exit(layout(1), add = TRUE) in chunks that use
        layout(...).
  - No changes to options() or working directory in examples/vignettes.

                        Changes in version 0.1.1                        

  - First public release (submitted to CRAN).
  - Added Zenodo DOI and updated citation information.
  - Updated vignettes (index.Rmd and benchmark.Rmd) with correct version
    numbers and DOI.
  - Clarified that the FFT backend supports only sum and mean; other
    statistics handled by the terra backend.
  - README and DESCRIPTION updated for consistency (license MIT, DOI,
    installation instructions).
  - Added inst/CITATION file so that citation("fastfocal") prints the
    DOI and pkgdown URL.

                        Changes in version 0.1.0                        

  - Internal development version (not submitted to CRAN).
