Changes in version 0.4.2                        

  - Sped up spectral alignment to further improve speed of spectral
    library searching (by about 50%).
  - Added additional plot functions for ms_alignment objects:
    plot.ms_alignment and boxplot.ms.alignment.

                        Changes in version 0.4.1                        

  - Refactored spectral_similarity to speed up spectral library search.
  - Silenced warnings for malformed database entries in spectral library
    search.

                        Changes in version 0.4.0                        

  - Changed name of package to "mzinspectr".
  - Updated ms_filter_alignment so it filters matches when removing
    columns from the peak table.
  - Added titles to mass spectra plots with peak name and retention
    index or time.
  - Fixed bug in retention index matching algorithm for
    ms_search_spectra function.
  - Added fixed_levels argument to ms_reshape_peaktable so features can
    be plotted in the order they're provided by the user.
  - Changed the name of the mzinspectr alignment object from
    msdial_alignment to ms_alignment.

                        Changes in version 0.3.3                        

  - Fixed bug ms_tidy_msdial when renaming peaks that are out of order.
  - Renamed ms_tidy_msdial to ms_reshape_peaktable. The old function
    name is now deprecated.
  - Made some improvements to documentation.

                        Changes in version 0.3.2                        

  - Added option to for renaming peaks via ms_tidy_msdial by providing a
    named character vector.
  - Deprecated treatment argument in ms_tidy_msdial, replacing it with
    new metadata argument.

                        Changes in version 0.3.1                        

  - Made rcdk (for rendering structures in ms_search_gadget) suggested
    instead of a dependency.
  - Simplified ms_read_alignment function and made corrections so that
    correct types are read in for peak metadata fields. Missing
    retention indices are now correctly entered as NAs.
  - Added error message to search_spectra when peak retention indices
    are not present and added option to search entire database by
    setting ri_thresh to NULL.
  - Corrected normalization functions so they now return the peak table
    as a data.frame instead of a matrix.

                        Changes in version 0.3.0                        

  - Added support for calling MSDIAL console app directly through the
    ms_call_msdial function.
  - Improved speed of ms_search_spectra function and added progress bar.
  - Removed search_msp from NAMESPACE.
  - Added ms_search_gadget for interactively viewing search_spectra
    matches.
  - Changed names of normalization functions: tsn to ms_normalize_tsn
    and pqn to ms_normalize_pqn.
  - Added ms_rt_to_ri function for conversion of retention times to
    retention indices.
  - Added ms_ prefix to all exported functions to prevent NAMESPACE
    conflicts.

                        Changes in version 0.2.0                        

  - Update license to GPL3.
  - Added a NEWS.md file to track changes to the package.
  - Added search_spectra & search_msp functions for peak identification.
