    + XYZ Channels (new): Create XYZ data from three images (values
      and precise X and Y coordinates).
    + DM3: Raw data are no longer scaled by inverse maximum
      representable value.
    + Coerce: Skew-normal distribution was added.
    + Volume Show and Extract: Cleanup; functions superseded by
      Cut'n'Slice were removed, visualisation and stability improved.
    + MFM modules: Cleanup; a few wrong numerical factors were
      corrected.
    + Volume Z calibration: Calibration can be also taken from another
      volume data.
    + Volume Swap Axes: Preview image units correspond to the
      transformed data.
    + NMM file: Sometimes incorrect import when a only subset of
      channels is selected was fixed.
    + NRRD file: Import from text-encoded files was corrected. Endian
      is no longer required for text data.
    + PNI file: Support for v2.0 files was added, at least for a
      subset of data types.
    + Volume slice: Mislabelled axes on output graphs were corrected.
    + Transfer function (PSF) guess and fit: The set of output images
      can be controlled

      pattern are merged, not just with names starting from 1. When
      files do not seem numbered at all, the single selected file is
      loaded instead of failing.
    + Basic operations: Function for flipping around the diagonal was
      added.
    + Pattern synthesis: Holes are placed with respect to image centre
      instead of some defined but unhelpful origin of
      coordinates. This means generated images also changed and match
      previous versions only statistically.
    + Graph logscale: Logarithm base mishandling was fixed. Base-2
      logarithm and negative abscissa handling options were added.
    + Statistical quantities: Volume was added as a new quantity.
    + FFT profile: Renamed to 2D PSDF. It can now both extract
      profiles and create the entire 2D PSDF image.
    + Image export: Font selection having sometimes no effect on the
      exported image was, hopefully, fixed. It no longer crashes when
      there is no image to export.
    + Filters tool: The median filter now uses circular kernel.
    + 2D ACF: Creation of the output image is optional. The image can
      be limited to the zoomed part.
    + Volume summarize profiles: The value for the currently selected
      profile is displayed in the dialogue.
    + Dimensions and Units: Crash when reinvoked after selecting Match
      pixel size was fixed.
    + Pygwy: Function gwy_app_data_browser_get_containers() no longer
      leaks references to all the returned Containers. GraphModel
      supports the sequence protocol.
  * Other
    + Compilation: pygobject2 codegen is no longer required to build
      pygwy; an embedded implementation is used when it is not
      available.
    + Compilation: autogen.sh no longer gets stuck without gettextize;
      it prints an error message.

      of being regularised to image upon import.
    + Statistical functions: Local range was added as a new quantity.

    + libgwyprocess: Functions for filling area under mask with a
      value and simple data-average correction using unmasked data
      were added.
    + libgwydgets: Gwy3DView no longer downsamples data during
      changes, all operations are done with full-resolution
      surfaces. Its "reduced-size" property was deprecated and it has
      no effect.
    + libgwydgets: Gwy3DView light source distance from the surface no
      longer scales with Value scale, improving views with small Value
      scale a lot.
    + libgwydgets: Graph labels respond to "label-property"
      changes. The property is also meaningfully updated when user
      moves the label around.
    + libgwydgets: GwyGraphModel and GwyGraphCurveModel clone()
      methods were implemented.
    + libgwyapp: gwy_app_channel_remove_bad_data() now ensures the

      was corrected so that can be activated only when there is
      actually an active image.
    + Processing modules with selections in the dialogue: Critical

      the function after deleting a channel was fixed.
    + Rawfile: Replacement value for missing data can be given as text
      for text formats, e.g. ‘BAD’ or ‘NODATA’.
    + Raw XYZ: A bug in point merging was fixed that sometimes caused
      infinities to appear in the data. Triangulation is remembered
      and not recomputed when not necessary. A progress bar is shown
      for the trianguation process and it is possible to cancel
      it. New interpolation type ‘Average’ was added, which is always
      fast and produces a result similar to a bit fuzzier ‘Round’
      interpolation. Button ‘Reset Ranges’ permits resetting the data
      ranges to the initial values obtained from the file data
      ranges. Point density can be plotted as another field.
    + GWYXYZF: The regularisation method was improved to ‘Average’
      from Raw XYZ.

  * Application
    + Translations updated: Czech, French, Italian, Russian.
  * Libraries
    + libgwyddion: GwyContainer items are serialised in lexical order
      (this is not a functional change; the order is still not
      guaranteed by the format).
    + libgwyddion: New functions gwy_fopen() and gwy_fprintf() were
      added, wrapping the C library functions. As they reside within
      Gwyddion they are always compiled with the same C library on MS
      Windows (unlike g_fopen()), making FILE pointer passing
      possible.
    + libgwyprocess: Functions for erosion, dilation, opening and
      closing morphological operations with arbitrarily shaped flat
      structuring elements were added.
    + libgwyprocess: A function for alternating sequential filters

      perform all types of distance transforms now, including true
      Euclidean.
    + libgwyprocess: Functions for mask growing and shrinking using
      any available distance measure were added.
    + libgwyprocess: A function for mask inversion was added.
    + libgwyprocess: A function for trimming empty border rows and
      columns from a mask data field was added.

      (may not be meaningful or supported for all subclasses).
    + libgwydgets: GwySelectionGraphArea and GwySelectionGraphPoint
      support crop and move methods now.
    + libgwydgets: Graph selections that are either along x or y have
      now an "orientation" property, similar to GwySelectionAxis.
    + libgwydgets: GwyColorAxis updates properly after exact range
      inversion.
    + libgwyapp: Drag'n'drop of selections from Selection Manager tool
      to channels works for images with offset top-left corner.

      replacement. It is possible to specify a raw value representing
      missing data. Support for two-byte half and six-byte Pascal
      floating point formats was added. Reading of 64bit integer
      formats was fixed.
    + Filters tool: Minimum and maximum filters now use circular
      neighbourhoods. Opening and closing filters and alternating
      sequential filters with flat discs were added. The filters can
      be applied only to masked/unmasked parts of the image.
    + Rank: Local normalisation and value range filter options were
      added.
    + Nanoscantech: Unit and scale reading was updated.
    + Mask editor tool: The distance type used for Grow and Shrink is
      controllable now, with true Euclidean distance being the
      default. Using bucket fill on an image with no mask creates a
      mask and fills it entirely.
    + Profile tool: Possible crash when starting to take a profile
      with masking was fixed.
    + Axis, Ellipse, Line, Point and Rectangle layers: Support for the
      move peration was added.
    + Selection manager tool: Selections are distributed correctly
      from and to images with offset top-left corner.

      numbering and grain quantity calculation were added.
    + Slice volume, Align rows: It is possible to select a target
      graph for extracted curves.
    + Align rows: All the methods consistently keep the mean
      correction to zero, preserving absolute data values. A Critical
      warning message in column aligment of non-square images when
      mask was present but ignored was fixed.
    + Mark by threshold, Mark by edge detection, Facet analysis: The
      mask can be combined with mask already present on the image
      using union or intersection.
    + Mark by threshold: Reset button now really resets all the
      settings.
    + Color range tool: Can reverse the mapping for fixed
      ranges. Mapping range is no longer reset to full upon data
      change.
    + Object synthesis: Features created on the surface can be
      positive, negative or randomly ehtier now.
    + NT-MDT: Hybrid mode data are split to upward and downward
      movement.
    + CSM: Image dimensions from Benyuan header are ignored now and
      BMP dimensions are always used.
    + Nanoscope: Calculation of dimensions of non-square images was
      improved (hopefully).
    + Image export: Smaller pixel-per-inch values are possible for
      vector formats and the values are also no longer rounded to
      integers.
    + WSxM: Horizontally flipped exported channels were fixed.
    + Omicron flat: Files with non-standard names are loaded now, with
      no related data loaded alongside. The original result filename
      is displayed as the filename when possible.
    + Critical dimensions: No longer crashes or produces NaNs when the
      profile does not conform to Step profile according to the norm.
    + GWYXYZF: Incorrect memory freeing, possibly causing leaks or
      crashes, was fixed.
    + 2D FFT: Crash for raw inverse transform without any imaginary
      part selected was fixed.
  * Other
    + Dependencies: Gwyddion can use either minizip or libzip for
      opening of ZIP-compressed file formats. The former is used if
      both are found.
    + Unix compilation: Configure checks for gtk-doc at least 1.10,
      required to build the documentation (older versions were
      actually insufficient even before).
    + Linux compilation: RPM requires rubypick only on RedHat-based
      distros.

- changes from version 2.42:
  * Application
    + Translations updated: Czech, French, Russian.
  * Libraries

      added.
    + libgwyprocess: New functions to calculate data line total
      variation, skew, kurtosis, mean absolute deviation of values and
      peak statisics.
    + libgwyprocess: Normalisation of tan β₀ data line statistics was
      corrected.
    + libgwyprocess: New functions for obtaining GwyDataLine minimum
      and maximum values simultaneously.
    + libgwyprocess: Range and total variation can be now calculated
      by gwy_data_field_area_get_line_stats().
    + libgwydgets: Gradient visualisation mode uses the same false
      colour mapping as overlay if overlays are set.
    + libgwydgets: 3D view false colour map rendered as a black box
      when no axes are drawn was hopefully fixed.
    + libgwydgets: Leaking overlay GwyPixmapLayers in Gwy3DView were
      fixed.
