…and the actual list of changes in 2.61 follows. Sorry about posting the
2.60 news instead.

Application:
- Translations updated: Czech, French, Russian.
- Command line: New option --convert-to-gwy merges and converts SPM files to
  the Gwyddion file format.
- Command line: Non-GUI operations --identify, --check and --convert-to-gwy
  avoid more carefully GUI initialisation code, fixing some warnings.

Libraries:
- libgwyddion: gwy_check_regular_2d_grid() gives better offsets and steps.
- libgwyddion: GwySIUnit parser handles better Unicode powers like 10³ or m².
- libgwyddion: New gwy_math_curvature_at_origin() curvature function.
- libgwyprocess: GwyLawn deserialisation segment data size check was fixed.
- libgwyprocess: Elliptic area extraction and unextraction, broken in 2.59,
  work correctly again.  This fixes intersection with an elliptic area in Mask
  Editor tool.
- libgwyprocess: Rectangular pyramid shape fitting preset was added.
- libgwyprocess: Shape fitting preset parameters can have descriptions.
- libgwyprocess: gwy_data_field_row_gaussian() no longer limits kernel size
  using the vertical resolution.
- libgwyprocess: Function for changing the number of GwySurface points without
  immediately filling it with new data.
- libgwyprocess: A Zoom FFT function was added for GwyDataLine.
- libgwyprocess: New function for a linear combination of two GwyDataLines.
- libgwyprocess: GwyPeaks should no longer produce NaN peak widths for odd
  peak shapes.
- libgwydgets: Gwy3DView draws correctly the false colour axis for inverted
  gradients and follows better mapping changes made in the false colour tool.
- libgwydgets: gwy_color_axis_set_unit() invokes a redraw even if the same
  object is set again.
- libgwydgets, libgwyapp: GtkTooltips functions were deprecated (use the simple
  GtkWidget functions instead).
- libgwyapp: Incorrect warning about the default value in
  gwy_param_def_add_string() was fixed.
- libgwyapp: Crash in GwyParamTable radio button row construction was fixed.
- libgwyapp: gwy_param_table_reset() no longer tries to reset foreign controls.
- libgwyapp: New predefined parameter type for a set of grain value groups.
- libgwyapp: A helper function for adding a vector layer to a preview.

Modules:
- Nova ASCII (new): Imports NT-MDT Nova exported ASCII data.
- Indentor analyze: Completely rewritten, with useless quantities removed,
  useful added and region marking improved.
- Dimensions and Units: Bug sometimes causing it to forget the dimensions mode
  was fixed.  For Set range and Correct by factor the unit is remembered in
  settings.
- Graph Flip, Graph FZ to FD: Output data order which was causing problems in
  subsequent processing was fixed.
- Corning: Import of Corning Tropel UltraSort TTF files works now too.
- Nanonics: Raw data conversion factors were improved; some data may still be
  imported wrong.
- Nanoscope: Single force curve rebasing was made more robust.
- Curve Map Nanomechanical Fit, Fit FD Curve: Miscellaneous model improvements.
- GwyTIFF: Byte counts and offsets are read correctly when of type short.
- WRUST: Support for Liczba Kolumn parameter was added. Extra empty lines in
  header are ignored.
- 3D formats: Fixed import of STL files which was reading only some points and
  some multiple times.
- Anfatec: Also imports FV matrix data (as curve maps).  Metadata are created
  from the header file.
- Pixmap, HDR image: Option to simply use the pixel dimensions as the lateral
  dimensions was added.
- Wrap value: Option to keep the current data range unchanged was added.
- Grain correlations: Quantities available for abscissa are updated correctly
  when it is calculated from a different image.
- Measure lattice: Masking support was added.  Vector numbers can be displayed.
  The FFT image is refined.
- Tip model: Can enforce square tip image.
- Fit Shape: Pressing OK again consistently produces output images, whether
  they originate from fitting or just setting parameters manually.  Most
  parameters have toolips with descriptions.
- Perspective correction: Correction can be applied to all compatible images
  and it can modify the current image (instead of creating a new one).
- Projective selection: Supports crop and move and can be distributed by the
  selection manager tool.
