Legend velocity can be constant (eg, 2 cm/yr), or variable (to keep arrow length within reasonable limits).
Projects and recent sessions:
Fixed problems loading projects saved on computers with different locales:
The following backward/forward compatibility rules now apply:
Can load the following on 2.1:
Projects saved with 2.1 on any locale:
Only projects saved with 2.0 on English locale or same locale (if not English):
Can load the following on 2.0:
Projects saved with 2.1 on any locale, but must be loaded on English locale.
Only projects saved with 2.0 on matching locale.
Added triangulation draw mode in topology network (brown) layers.
Can draw boundary, mesh or fill (independently of colour mode).
Strain rate and accumulated strain:
Added total strain rate.
Added exports for the following accumulated strain quantities:
Principal strain and stretch.
Added optional strain rate clamping:
Finite strain is now correctly accumulated.
Fixed crustal thinning (gamma) factor.
All three crustal thickness types now created when generating crustal thickness points.
Calculate statistics using entire history of crustal thicknesses/factors (instead of just at initial time).
Fixed missing IMPORT_AGE attribute in OGR vector formats (eg, Shapefile).
Enable import and export of NetCDF version 4 rasters (via GDAL library version 2).
Support export of gridline registered rasters.
Time-dependent raster (and 3D scalar field) import now supports times (depths) anywhere in filenames.
Fixed incorrect half-pixel shift downwards (North to South) for gridline registered global GMT grids.
Fixed semi-transparent vertical seam near North and South poles at longitude 0 or -180.
Make GMT velocity export compatible with GMT psxy "-Sv" and "-SV" command-line options.
Assign all known feature types a random colour in Feature Type draw style.
Fixed vertex edits not modifying topologies.
Digitize New Geometries:
No longer offer Reconstruction/Conjugate Plate IDs for topological networks and topological lines.
Point-in-polygon test now considers points on a polygon edge (within extremely small tolerance) to be inside polygon.
Fixed point proximity to a polyline/polygon in rare situations.
GPlates Geological Information Model (GPGIM):
Loosen constraints on properties that can be loaded from a GPML file.
Only disable surface mask functionality in 3D scalar fields for problematic graphics driver/hardware.
...and other changes listed in the CHANGELOG file in the GPlates source-code releases.
GPlates 2.1 compiles and runs on Windows 7/8/8.1/10, Linux and MacOS X.
Download GPlates 2.1 from the Download page.
GPlates-compatible data have been made available, and has been updated and extended in many ways for the GPlates 2.1 release. For more information, see the Download page.
PyGPlates enables access to GPlates functionality via the Python programming language. This may be of particular use to researchers requiring more flexibility than is provided by the GPlates user interface.
The pyGPlates binaries currently require Python 2.7, however the pyGPlates source code now works with Python 3. PyGPlates compiles and runs on Windows 7/8/8.1, Linux and MacOS X.

The pyGPlates documentation and tutorials are available on the User Documentation page and includes:
The pyGPlates tutorials are Jupyter Notebooks that analyse and visualise real-world data using pyGPlates. These tutorials complement the sample code in the pyGPlates documentation by providing a more research-oriented focus.
