Gwyddion full changelog

Application:
Translations updated: Czech, French, Russian.
Libraries:
libgwyddion: gwy_check_regular_2d_grid() for more or less collinear points no longer fails with CRITICAL message.
libgwyddion: Random generator set can fill an array with random numbers, generating blocks of them in parallel.
libgwyddion: Possible buffer overflow in GwySIUnit unit parsing was fixed.
libgwyprocess: Value-inverted output of local normalisation filter was fixed.
libgwyprocess: Lateral scale of row-wise PSDF was fixed for area sizes smaller than the full data field.
libgwyprocess: New brick function for in-place flipping.
libgwyprocess: Elliptic area functions work with ellipses not fully contained in the data field.
libgwyprocess: New Lunette and Exponential shape fit presets were added.
libgwyprocess: Functions for general linear combination of two GwyDataFields was added.
libgwyprocess: Lattice refinement gives more weight to larger peaks.
libgwydgets: GwyAdjustBar is redrawn upon value reset to zero,

Application:
New translation: Japanese.
Translations updated: Czech, Russian.
Libraries:
libgwyprocess: Masked plane levelling works again.
libgwyprocess: Root mean square slope function data field function was added.
Modules:
Perspective correction (new): Correction of perspective distortion.
Projective layer (new): Vector layer for selection of perspective rectangles.
Pattern synthesis: Substantially rewritten with more patterns and more controllable parameters. Pattern parameters are not backward-compatible with previous versions.
Statistical quantities: Root mean square slope (Sdq) was added.
Selection manager tool: Machine-readable number format is always used in exported selections. Support for projective selections was added.
Renishaw: z-scans mapping is loaded now as separate graphs. Metadata loading from pset is slightly fixed.

Application:
Translations updated: Czech, French, Russian.
Libraries:
Libgwyddion: Fourth and fifth order polynomials NLFit presets were added.
Libgwyddion: Wrong heights fitted by Smooth slanted step model (by factor 2/π) were corrected.
Libgwyprocess: Artefacts in results of multithread min-max based filters (erosion, dilation, opening, closing, etc.) were corrected.
Libgwyprocess: Occasional completely empty borders produced by gwy_data_field_new_rotated() were corrected.
Libgwyprocess: Gaussian smoothed cone and pyramid shape fit preset models were added.
Libgwydgets: GwyDataView avoids trying to create zero-sized pixbufs, which could lead to rare crashes for large aspect ratio images.
Libgwydgets: gwy_graph_model_set_units_from_data_field() now emits notification that units have changed as it should.
Libgwyapp: Tool window properties no longer clutter the data processing log.
Modules:
Evovis XML (new): Import of Evovis XML profilometry data.

Libgwyddion: The broken and misguided geometric fit option of GwyNLFitter was made no-op.
Libgwyprocess: Power-exponential ACF fitting function was added.
Libgwyprocess: Function for conversion from 2D PSDF to angular spectrum was added.
Libgwyprocess: Unmasked gwy_data_field_area_dh() using data from the wrong place in the data field was corrected.
Libgwyprocess: ACF and HHCF functions with levelling argument now support value 2 (tilt removal).
Libgwyprocess: Functions for getting 1D minima and maxima positions with masking.
Libgwyprocess: Basic GwyDataLine artithmetic functions were added.
Libgwyprocess: Crticial dimension circle functions work again.
Libgwyprocess: Half-sphere fitting shape was added.
