                     Changes in version 1.3.1.9000                      

  - add_wavenumber_marker() and add_band() now respect label_aesthetics
    = list(vjust = ...) so peak labels can be vertically offset to
    reduce overlap (@pbulsink, #38).

  - fit_peaks() now documents explicit fitting controls and clarifies
    that automatic peak discovery is a heuristic starting point for
    fitting, not a validated deconvolution standard (#33).

  - Peak fitting functionality added with find_ftir_peaks(),
    fit_peaks(), and related functions. (#33)

  - Added Raman spectral plotting with plot_raman(), read_raman(), and
    utilities for baseline correction, smoothing, and peak finding
    (#34).

  - smooth_spectra(), baseline_correct(), normalize_raman(), and
    find_peak_maxima() accept sample_ids = NULL to select every sample
    (#34).

  - smooth_spectra() and baseline_correct() now report a clear error
    when given FTIR absorbance or transmittance data instead of Raman
    spectra (#34).

  - normalize_raman() now rejects spectra with a non-positive maximum
    and reports NA intensity values rather than silently propagating
    them (#34).

  - read_raman() captures single-# header metadata, reports true file
    line numbers for invalid data, and warns about malformed rows (#34).

                 Changes in version 1.3.1 (2026-09-17)                  

  - Updated package data sets to properly print after v1.3.0.
  - Added bilingual error codes and bilingual pretty printing (#40)
  - read_ftir_jdx() now auto-converts .jdx files with wavelength
    (micrometer) x-axis units to wavenumber (#43)

                 Changes in version 1.3.0 (2026-07-21)                  

  - print() now provides pretty printing for PlotFTIR data structures,
    showing spectral range, resolution, intensity type, number of
    samples, and sample IDs. (#27)
  - Updated to use ggplot2::coord_transform() instead of coord_trans,
    which is now deprecated. (#25)
  - Resolved issue with data exchange with ir package. (#35)

                 Changes in version 1.2.1 (2025-08-25)                  

  - Updates (mostly to testing) to comply with pending ggplot2 4.0.0
    release (#23)

                 Changes in version 1.2.0 (2025-03-31)                  

  - Patch update to expose check_ftir_data for downstream packages.
    (related to #19)
  - Add import capability for .jdx filetype using readJDX. (#20)

                 Changes in version 1.1.0 (2025-02-05)                  

  - Added ability to set default language in options(). (#10)
  - Added ability to highlight one or more samples in spectra. (#15)
  - Added ability to add a background shaded band (like a wide marker)
    to indicate a given range. (#16)
  - Added attributes to imported data to simplify internal calculation
    of thingslike y axis units. (#17)

                 Changes in version 1.0.0 (2024-11-13)                  

  - Initial Release & CRAN Submission.
