Version 3.10 becomes the new LT version at the end of February 2020
QGIS 3.10 "A Coruña" released

Splash screen QGIS 3.10 A Coruña

A few days ago version 3.10 "A Coruña" was released. A Coruña hosted the 2019 QGIS user conference, followed by a contributor meeting.

The Visual Changelog for 3.10 is now available, with a slight delay.

Some important improvements of this version are:

General

  • Browser: Styles from other QGIS projects can be loaded from the browser
  • Start screen: Templates for New QGIS Projects
  • Start screen: Display of news and dates of QGIS events
  • Expressions: improvements in attribute handling (attributes()), support for custom date/time conversion formats, collect_geometries() and improved make_line()

3D

  • New representation: Billboards (always looking towards user)
  • Measuring tool in 3D
  • 3D navigation buttons
Layout
  • GeoPDF export * and import with many useful options. See also separate blog post.
  • Improved SVG export (layer names) with possibility to reduce coordinate accuracy. Useful for further processing in Adobe Illustrator or Inkscape.
  • Print layouts: improved handling of map grids (dynamic grid mesh width adjustment, and data-defined mesh width settings)
  • Print layouts: graphics in legends optionally to the right of the text
  • Print layouts: support of spatial bookmarks for setting map sections
  • Numerous bug fixes
Labeling
  • Kerning support
  • Vertical text for Asian languages
  • Various fine-tuning and numerous minor improvements
Digitizing / Data acquisition
  • GPS timestamp support when recording GPS data
  • Digitization restrictions: support for allowed gaps (with thresholds) in the topology checks of a layer
  • The snapping cache is now set up in the background and no longer blocks QGIS.
  • Forms/Widgets: Live update for dependencies between 2 widgets (e.g. for default values depending on form entries)
Data Management and Provider
  • Composite primary keys are supported
  • Improved handling of circular layer dependencies (useful for snapping improvements)
  • Oracle data provider: auth-config support and transaction support (similar to Postgis transaction support)
  • Text data provider: support of Z and M values from attribute columns

Analysis and Processing

  • Raster calculator: new operators (abs/min/max)
  • Processing: GDAL algorithms now allow additional command line parameters that are supported by GDAL but are not otherwise exposed in the processing form.
  • Processing: new input parameters "File" or "Folder".
  • Processing: numerous improvements for style management
  • Processing: algorithm for cumulated height differences along a given line geometry, derived from a height model.

QGIS Server

  • SVG symbols can be loaded from URLs
  • WMS dimension support (e.g. time, altitude or other). This allows different map views taking into account the time dimension.
  • WFS-3/OAPIF support (based on REST and JSON)

* Footnote on GeoPDF support: GeoPDF export and import requires that QGIS 3.10 has been compiled against GDAL/OGR >3.0 and against proj6. Due to a dependency on GRASS-GIS, the current QGIS version is unfortunately compiled with an older GDAL/PROJ combination. Therefore the GeoPDF support is currently not available for the official Windows and Ubuntu builds.

Possible workarounds: Patience until the next point release (probably on 22.11.2019), installation via the OSGeo4W installer as described here or compile it yourself from the sources.


Thanks: for this version we would like to thank, among many other supporters, especially the State of Vorarlberg and the co-financers (City of Vienna, City of Dornbirn, Canton Zug (Archaeology/Denkmalschutz), Canton Neuchâtel and Canton Thurgau, as well as a British National Park). Together they made the development of the GeoPDF support possible.
