- Drop upstreamed fix-desktop-file.patch
- Add new BuildRequires: cmake(KF5NewStuff)
- Do not rename the .desktop and appstream data files any more, the
  names have been changed upstream

- Add Provides: labplot = %{version} and Obsoletes: labplot <
  2.3.0 to enable easy upgrade from openSUSE Leap 42.1 to 42.2,
  where labplot-kf5 2.3.0 should replace labplot. This assumes
  that the Leap 42.1 labplot (currently at version 2.0.2) itself
  does not get upgraded to a version above 2.3.0 via official
  maintenance updates. Remove Conflicts on labplot as a
  consequence.

- Add fix-desktop-file.patch to fix the Exec line in the .desktop
  file so labplot can be started from the application menu
- Add cantor-devel to the build requires to enable the new cantor
  integration

  * Integration of Cantor - Support for different open-source
    computer algebra systems

  * Interpolation of data including different splines, cosine,
    exponential, cubic Hermite (Catmull-Rom, cardinal,
    Kochanek-Bartels) and rational functions
  * Data smoothing using moving average (centered or lagged),
    percentile filter or Savitzky-Golay algorithm
  * Fourier filter (low pass, high pass, band pass, band reject)
    with ideal, Butterworth, Chebychev I+II, Legendre or
    Bessel-Thomson filter
  * Fourier transform with many window functions (Welch, Hann,
    Hamming, etc.) calculating magnitude, amplitude, power, phase,
    dB, etc. and supporting one/two sided spectrum with or without
    shift and x scaling to frequency, index or period

  * Fixed sporadic crashes during project close
- Drop upstreamed labplot-kf5-gcc5-isnan.patch

- Labplot does not show up in application centers (e.g.
  gnome-software) as appstream-builder expects the .appdata.xml
  file and .desktop file to have matching names; rename .desktop
  file to org.kde.labplot2.desktop as referenced in the
  appdata.xml file, and rename appdata.xml file accordingly.

- Add labplot-kf5-gcc5-isnan.patch: Replace isnan by std::isnan
  to fix building with gcc5.

  * New operations on columns in Spreadsheet - reverse, drop values
    and mask values.
