Changelog for QGIS 3.30


Release date: 2023-03-04

The 3.30 ‚s-Hertogenbosch release of the groundbreaking QGIS project introduces a wide range of changes and optimizations from the QGIS developer community.

The splash screen features a fragment of the “Gemeentekaart”, or Municipality map, of ‚s-Hertogenbosch from 1867. It is part of a series of 1200 maps of all the communities in The Netherlands from that time, which were published in an atlas for each of the 11 regions. All maps were drawn in the same size, although for large municipalities a double format was used and scaled to match the page. The series was internationally rewarded because of its accuracy and completeness. The map was drawn by Jacob Kuyper (1821-1908), the most famous geographer and cartographer of his time in The Netherlands. Text and splash map image provided by

The native GeoNode integration has also been migrated to an external plugin, leveraging the powerful extensions to the QGIS API for plugins implemented in recent releases.

Users can also look forward to new functionality and UX enhancements, including support for raster attribute tables, intelligent and configurable sorting for layer loading, improvements to GPS utilities, more dynamic form widgets, native rich media previews for attachments, better integration with cloud services, extensions to the QGIS metadata standards, and a host of other noteworthy additions.

Breaking Changes

Feature: Drop project backward compatibility for symbology with QGIS 3.16 and older

Previous releases of QGIS would write significant amounts of compatibility objects into the XML structure of project files to maintain backward compatibility for symbologies in order to allow project files to be opened with QGIS 3.16 and older. This compatibility has been removed from future releases.

This feature was developed by Denis Rouzaud


Feature: Raster MapTips

in previous releases, MapTips were only available for vector layers, but new API changes have made it possible to implement MapTips for other layer types.

Raster layers now support MapTips, and new expression utility functions have been added to extend the existing MapTips capabilities:

  • map_to_html_table: converts a map (key-value pair data structure) to an HTML table

  • map_to_html_dl: converts a map (key-value pair data structure) to an HTML definition list

  • raster_attributes: creates a map with the fields names as keys and the raster attribute table values as values from the attribute table entry that matches the given raster value

  • a new „Map Layer Position“ expression scope that defines a variable @layer_cursor_point with the layer coordinates (in the layer’s CRS) under the mouse position

Feature: Identify on mouse move, no mouse click

A new option allows for the use of the identify tool to be triggered on mouse movement, without needing to click on the canvas.

This option behaves almost identically to the default identify option, with the difference being that the user doesn’t need to click or use a keyboard shortcut to trigger the identify action. This allows the identify tool to function similar to the MapTips utility, whilst providing users with the benefits of the identify tool such as support for multiple layer types and derived information.

The default trigger is a 300-millisecond timer which will execute the identify action, which is implemented to avoid performance issues when moving the mouse.

Feature: Constraint based functionality for attribute tables

New constraint-based conditional styling and failing constraints feature filters have been exposed within the attribute table.

This functionality provides filtering options to view or hide features that have failing (hard or soft) constraints, and introduces a new conditional styling type that works alongside the pre-existing row and field types to highlight features which fail to meet the layer constraints.


This feature was developed by Mathieu Pellerin

Feature: Additional GPS information panel and toolbar fields

The GPS information panel now includes the current total track length, and the distance from start of track. These features are also available as a (not-on-by-default) option which allows them to be shown in the GPS toolbar information label.

The GPS information panel also includes ellipsoidal altitude in the available GPS information values.

This feature was funded by NIWA

This feature was developed by Nyall Dawson

Feature: GPS Information Panel UX and Refactoring

A substantial rework of the GPS information panel has been performed in order to simplify the user operation of GPS within QGIS and provide a more streamlined GPS experience.

Previously, all application-level GPS functionality was exposed through a single GPS „Information“ panel interface, which included GPS connection settings, digitizing from GPS, and the actual display of GPS information. This interface became cluttered and difficult to use

GPS functionality has now been split up into distinct parts:

  1. Application level, rarely changed GPS settings are present in the GPS tab of the Options menu within QGIS Settings.

  2. A new floating „GPS Toolbar“ has been added, which contains the most commonly used GPS-related operations.

  3. The final action in the GPS Toolbar opens a „GPS settings“ popup, that contains various settings that are expected to be modified mid-session and are expected to be more readily accessible.

  4. The GPS information widget has been redesigned to show only GPS information. Specifically, only the „information“ and „signal“ tabs remain. The GPS information widget still contains a shortcut to the connect/disconnect action, and also a settings button that exposes the same GPS settings menu as is used in the GPS toolbar.

The GPS information widget class is now responsible ONLY for showing the GPS information in the panel, and new dedicated classes have been created for handling digitizing from GPS, the new GPS toolbar, and GPS settings accordingly.

Feature: Improved SLD Export Options

A new extension of the Styled Layer Descriptor (SLD) export API has been developed which exists in parallel with existing SLD export options, but provides additional functionality for the granular control of SLD exports.

This development includes the export of complex polygon layer styles as external graphic symbols which are stored alongside the exported SLD.


This feature was developed by Alessandro Pasotti


Feature: Global map terrain shading

Users are now able to apply a global terrain shading effect to the map, which is based on the elevation of all the active layers that support elevation, including :

  • Raster layers (if „Represent elevation Surface“ is checked in the layer properties)

  • Mesh layers

  • Point cloud layers.

The elevation value at any particular position for all the relevant layers are combined, and the considered elevation is chosen depending on one of two user defined methods:

  • The highest elevation is considered

  • The elevation on the topmost layer in the layer tree is considered

The implementation of shading methods are currently the Eye Dome Lighting and the hill-shade effect.

Elevation shading settings are exposed to the user interface in the following controls:

  • In project properties, in the same tab of the project elevation settings

  • In the layer styling panel, a new tab has been created for defining global terrain shading settings

Feature: Add super and subscript support for text renderer

Text items in QGIS now support superscript and subscript.

This allows for:

  • <sup>superscript</sup> / <sub>subscript</sub> components in text, where the text will be vertically super or subscript aligned and automatically sized to 2/3rd of the parent font size. Users can also set a fixed font size for the super/subscript by including the relevant CSS rules in their HTML, e.g. <sup style="font-size:33pt">super</sup>

  • vertical-align: super or vertical-align: sub CSS formatting rules in any other HTML element


This feature was funded by OSGEO UK

This feature was developed by Nyall Dawson

3D Features

Feature: Limit 2D extent of 3D scene

The rendered extent of a 3D scene can now be constrained to features that intersect a user-specified 2D extent.

The manner in which rendered features are limited is dependent on the source data layer type:

  • Flat, DEM, and Online Terrain are clipped at the specified extent

  • Point cloud layers only load points within the specified extent

  • Vector layers only load features that intersect the specified extent

Extent-based feature filtering on mesh layers is still currently in development.

This feature was developed by Stefanos Natsis

Feature: Improved camera control

There are a couple of improvements that improve the user experience:

  • Elevation range is taken into account when „Zoom full“ is used (users should not end up „behind“ their scene anymore)

  • Move camera vertically using Ctrl + Shift + Left mouse button

  • Allow wheel zooming while moving the mouse

  • Continue right mouse button zooming when pointer exits the viewport

This feature was funded by QGIS Community Crowdfunding Efforts

This feature was developed by Stefanos Natsis (Lutra Consulting)


Feature: Add feature_id() function

A new feature_id($feature) expression function now allows for retrieving the feature ID of a feature object.

The function accepts one argument which must be a feature object. Accordingly, this function can be used with the results of any other function which returns feature objects, such as „get_feature“, „overlay_*“, etc.


This feature was developed by Nyall Dawson

Feature: New is_feature_valid() and is_attribute_valid() functions

New is_feature_valid() and is_attribute_valid() functions are provided in QGIS expressions. Both functions validate a feature or attribute, based on the constraints attached to fields for a given vector layer. This enables users to leverage the select-by-expression utility to locate features that have unmet constraints. In addition, users can now use the rule-based renderer to provide visual feedback through symbology indicating the constraint validity state of rendered features.


This feature was developed by Mathieu Pellerin

Feature: Add x_at, y_at, z_at, m_at expression functions

The available $functions are considered deprecated ($x_at``and``$y_at`), and instead of operating on the current feature geometry the functions instead support a feature geometry as arguments.

The changes for these expressions include the creation of similar functions for other geometry measurements. These new functions include:

  • x_at(geometry, i)

  • y_at(geometry, i)

  • z_at(geometry, i)

  • m_at(geometry, i)

This feature was funded by Métropole Européenne de Lille

This feature was developed by Antoine Facchini

Data Management

Feature: DateTime Field editing: segregation of display format and field value format

Efforts to improve the management of datetime field information include the explicit definition of localization formatting for the display of datetime fields, whilst ensuring that the editing, capture, and storage of the field values conforms with international time formatting standards.

This feature was funded by 3liz

This feature was developed by rldhont

Feature: Add option to directly log GPS points and tracks to a Geopackage or Spatialite db

When activated in the GPS toolbar settings, the „Log to Geopackage/Spatialite“ action will prompt the user to select an existing GPKG or SpatiaLite file, or enter a new file name. A „gps_points“ and „gps_tracks“ table will be created in the file with a predefined structure.

All incoming GPS messages will be logged to the gps_points layer, along with speed/bearing/altitude/accuracy information from the GPS.

When the GPS is disconnected (or QGIS is closed), the entire recorded GPS track will be added to the gps_tracks table, along with some calculated information like track length, and start and end times)

This feature was funded by NIWA

This feature was developed by Nyall Dawson

Feature: Add an explicit „Offset from UTC“ option for storing GPS feature timestamps

This option allows users to manually enter a desired offset from UTC for storing GPS time stamps. This allows for full flexibility for users who need to account for daylight savings offsets or other complex time zone issues.

This feature was funded by NIWA

This feature was developed by Nyall Dawson

Feature: Raster Attribute Tables (RAT) Support

QGIS now includes extensive support for Raster Attribute Tables (RATs).

These updates provide a new RAT interface within the QGIS API, and support is provided for RATs managed by raster data providers (GDAL), as well as for generic value attribute table (VAT) files, provided that they are stored in an auxiliary DBF sidecar file.

Much of the functionality from the Python RAT Plugin was ported into QGIS to provide native support for RATs, and a new set of GUI operations affords users the following advanced functionalities:

  • Automatic raster styling: If a RAT is available when adding a raster to the project and includes style information, QGIS will apply the relevant styles to the raster layer by default. Automatic loading works for both embedded RATs and sidecar VAT.DBF with same basename of the raster.

  • RAT reclassification: Reclassification of a raster can be performed by selecting a different column

  • RAT Identify: Values from the RAT row corresponding to the relevant pixel value are shown in the identify Map Tool

  • RAT properties: A new „Attribute Table“ tab is available from the raster layers property window

  • RAT editing: RATs offer basic editing capabilities

  • RAT creation from current classification: RATs can be created from existing paletted or singleband pseudocolor styles

A gallery of these functionalities in action is available on GitHub

This feature was developed by Alessandro Pasotti

Metadata and Metasearch

Feature: Add key dates to layer and project metadata

The following fields have been added to the QGIS layer/project metadata standard:

  • Date created

  • Date published

  • Date revised

  • Date superseded

In previous releases, layer metadata had no date fields, whilst project metadata include only the created date field

This feature was developed by Nyall Dawson

Forms and Widgets

Feature: Audiovisual multimedia attribute attachments support

New functionality introduces multimedia support for the external resources widget, allowing users to playback audio and video media files in the attachments viewer.

This change includes additional configuration options for external resources, with two new items in the integrated viewer type combo box. The video type will take into consideration the height set by the user. If it’s left to auto, the video widget will grow to fill available space.

This functionality includes the development of the QgsMediaWidget object into the QGIS API for extended multimedia support.


This feature was developed by Mathieu Pellerin

Feature: Data defined editable state for form widgets

The „Editable“ checkbox status can now be controlled through an expression, the expression supports the „form“ context, meaning that it can use current_value( '<field_name>' ) to dynamically change the editable status according to changes to other fields in the form.


Diese Funktion wurde finanziert von Kanton Solothurn

This feature was developed by Alessandro Pasotti

Feature: Spacer widget for drag & drop attribute forms

A new spacer widget is provided, with the option to draw a horizontal line, affording users a greater degree of control for how forms are rendered for end users and extending functionality for improved UX with thematic breaks and improved alignment.

The widget renders as a blank space in the form, which creates a manual separation between other form objects.

When the „Draw line“ option is set in the configuration it will fill the vacant space with a line in a manner similar to the horizontal rule, or <hr> tag in html.


Diese Funktion wurde finanziert von Kanton Solothurn

This feature was developed by Alessandro Pasotti

Feature: Dynamic text widgets with current_value support

Text widgets now support dynamic configuration based on the values of fields present in the current form context by providing a current_value() function which may be evaluated within a QLabel object.

Using the current_value(  '<field_name>' ) expression will evaluate and update the form when the form field value changes.

Feature: Multiple selections with filtering in value relation widget

The Value Relation widget previously ignored „Use completer“ option when „Allow multiple selections“ was enabled. Now these two options work together and there is a search box present at the top of the table, allowing filtering of values. When „Use completer“ option is not enabled, the search box is not shown as before.


This feature was funded by QGIS Norway

This feature was developed by Stefanos Natsis (Lutra Consulting)


Feature: New layer ordering improvements

New options for configurable layer tree insertion methods, and the automated sorting of layers added via drag and drop functions, are now available in QGIS.

The previous behavior was for QGIS to always load new layers above the currently active layer.

New options have been provided to allow for more control of how new layers are added to projects:

  • (Always) On top of the layer tree

  • Optimal index/position within the currently active layer’s group

The optimal index will attempt to intelligently order layers by type (e.g. points on top of areas etc.) and provide a significantly improved experience for new users.

In addition, drag and drop added layers will be added to the layer index tree at the location of the cursor when released to ensure the layer is rendered in a predictable and intuitive manner.

Feature: Additional options for XYZ Tile exports when using Leaflet html output

Three new optional advanced parameters have been exposed for the XYZ Tile generation algorithm:

  • Leaflet-HTML-Ausgabekachel

  • Leaflet-HTML-Ausgabezuschreibung

  • OpenStreetMap-Basiskarte in Leaflet-HTML-Ausgabe einschließen


This feature was developed by Björn Hinkeldey

Feature: Support data defined parameter values when using qgis_process tool

While many processing algorithms supported data-defined parameter values, these were not possible to specify when using the qgis_process tool (or when representing algorithm settings as JSON and qgis_process commands), introducing limitations for utilizing QGIS within command line processing operations.

A new syntax is now provided to allow the specification of data-defined parameter values when running qgis_process operations, and copying the algorithm settings from QGIS will now correctly handle data-defined values.

Command line arguments are specified with the expression: prefix within an encapsulated string, whilst the JSON definition is implemented using an expression object with a data_defined type definition. Note that special characters within the expression will need to use the appropriate escape characters relevant to the context in which they are used.

Considering the expression @variable*"field_name"*to_int('2')/100 for the following examples, the command-line syntax would be:


Whilst the JSON representation would be:

"inputs": {
    "expression": "@variable*\"field_name\"*to_int('2')/100",
    "type": "data_defined"

This feature was developed by Nyall Dawson

Feature: New „load_layer“ function

A new load_layer expression function has been made available (exclusively for Processing expressions for the time being), which allows the loading of a map layer using a source string and provider name.

It is designed to allow the use of the expression functions which directly reference map layers (such as the aggregate functions) with a hardcoded layer path.

This permits the usage of these functions to be used outside of a project (such as via the qgis_process tool) and perform operations such as utilizing complex aggregate functions in the refactor fields algorithm via the qgis_process utility without creating a temporary project for data manipulation.

This feature was funded by the Research Institute for Nature and Forest, Flemish Govt

This feature was developed by Nyall Dawson

Feature: Add user interface for extent definition in GDAL Raster Calculator

The GDAL Raster Calculator now includes an interface for user-specified extent definition, so that users no longer have to specify the --extent criteria in advanced options.

This feature was developed by Nicolas Godet

Anwendungen und Projektoptionen

Feature: Add option to store selected GPS component in geometry M values

This new setting, available from the GPS settings panel, allows users to opt into creating geometries with M values from the inbuilt GPS logging tools. This applies to both features digitized from GPS logs, and from the new „Log to GeoPackage/SpatiaLite“ functionality.

Options include the storing of timestamps (as milliseconds since epoch), ground speed, altitudes, bearings, and accuracy components as m values.

This feature was funded by NIWA

This feature was developed by Nyall Dawson

Feature: Make GPS track destination layer an explicit user choice, remember in project

In previous releases, the destination layer for newly created GPS digitized features always followed the current layer selection. This made it very tricky to design projects around GPS digitizing, as whenever a user started interacting with the project the captured GPS features would be placed unpredictably within the available layers.

The GPS feature destination layer is now an explicit choice made by the user. A user can set this layer, and then go ahead and interact with the rest of their project layers and be guaranteed that any time they hit the actions to create GPS features these features will be put into the correct layer. The destination layer is stored in the current project, so reopening a prior project will automatically restore the GPS destination layer (also making it easier for staff or scripts to create GPS digitizing projects in advance for other users and be confident that these will work correctly in the field).

Additional enhancements include:

  • GPS destination layer is now made automatically editable when a feature is created, and the user is notified accordingly. This follows the approach we use for the interactive labeling tools and avoids user frustration where the features were previously not saved without any guidance as to why.

  • The GPS toolbar actions now more intelligently follow the state of the project, GPS, and current GPS track, so that actions are only enabled when they make sense

  • UI improvements and better tooltips

Profile Plots

Feature: New elevation profile canvas item for QGIS Quick

A new elevation profile canvas item is available for QGIS Quick, allowing the elevation profile tools to be used in other cross platform and mobile QGIS applications.


This feature was developed by Mathieu Pellerin

Feature: Elevation profile plots in print layouts

It is now possible to include profile plots in print layouts! There is a new „Add Elevation Profile“ button in the toolbar which will initially create an empty plot. A plot can be initialized by clicking „Copy From Profile“ button in the properties of the elevation profile item - this will use the active elevation profile from the main window of QGIS.

The elevation profile has wide configuration options - you can specify:

  • what layers to include

  • tolerance of the profile curve

  • chart ranges (minimum and maximum distance/elevation)

  • chart area borders and colors

  • distance and elevation axes properties - intervals of labels, grid lines appearance, fonts and more

Feature: Add dataset relationship editing and creation capabilities in browser

This functionality allows for the creation of new embedded relationship definitions in database files for ESRI FileGeodatabases, GeoPackage, and sqlite databases.

Deleting and modification of existing relationships is also supported, however the available functionality may depend on the constraints of the actual database format.


This feature was funded by Provincie Zuid-Holland

This feature was developed by Nyall Dawson


Feature: Removal of Native GeoNode Provider

The Native GeoNode Provider has been removed from QGIS and is now instead available as a plugin.

This change is due to the extension of plugin APIs to support the necessary functionalities, such as the data source manager, and was executed in line with QEP 262.

This feature was developed by Giovanni Allegri

Feature: In data source manager, allow users to directly add an XYZ tile layer without having to create a connection first

Users may now directly add an XYZ tile layer in the data source manager, without having to first create a new connection.

This permits users to easily add ad-hoc XYZ layers to their map without polluting their lists of saved connections.


This feature was developed by Nyall Dawson

Feature: SQL Logging for OGR Provider

As GDAL now supports query logging callbacks for SQLite-based layers, QGIS leverages this functionality to allow for query logging in the QGIS debug tools.

This is available for OGR-based SQLite data sources (SpatiaLite/ GPKG).

This feature was developed by Alessandro Pasotti

Feature: S3 Cloud Storage Support

S3 compatible cloud storage, such as AWS S3 and MinIO, are now supported as a method for accessing and storing external files, made available by using the external storage UI for cloud storage of attachments.

A new QGIS Auth method named „AWS S3“ has been provided to support connecting to services using the S3 protocol.

This feature was funded by Métropole Grand Lyon**

This feature was developed by Jacky Volpes

Feature: Resolution aware WMTS layers with automatic upscaling

QGIS now allows for WMTS layers to take device screen resolution, or dots per inch (DPI), into account and scale up the tile resolution on high DPI screens.

A new combo box has been added in the new WMS and WMTS server dialog for configuration of the WMTS tile pixel ratio. This allows QGIS to automatically handle the scaling up and down of tiles retrieved from the service based on the rendered DPI.

Note that enabling smooth pixmap transform is recommended when automatic upscaling is active


This feature was developed by Mathieu Pellerin

Feature: Drop unmaintained SAGA provider from QGIS installations

This provider has not been maintained and does not work with newer SAGA versions. Users are encouraged to use the 3rd-party „Processing Saga NextGen“ plugin instead.

After many many years of discussion, it’s time for the inbuilt provider to go!

This feature was developed by Nyall Dawson

Feature: Improve support of layers with unknown geometry type for WFS provider

The QGIS WFS provider has been improved to look in the response to the GetCapabilities request (if using WFS 2.0) if the IsPoint, IsCurve, IsSurface extended filter functions are present.

When such a layer is added to the project, a „Select Items to Add“ dialog box is displayed.

This enables the user to select one or several layers among ones of NoGeometry, MultiPoint, MultiCurve, MultiSurface, GeometryCollection types.


This feature was funded by QGIS-DE user group

QGIS Server

Feature: QGIS_APPLICATION_FULL_NAME environment variable

This change defines the QgsApplication::applicationFullName() method for use with PostgreSQL application_name and QGIS Server Logging.

For QGIS Server, the QGIS_SERVER_APPLICATION_NAME can be specified instead and will take precedence over the QGIS_APPLICATION_FULL_NAME setting.

The value may also be specified in the /qgis/application_full_name variable in the QGIS Server config file.

By default, this value will be defined by the value of QgsApplication::applicationName()+' '+QgsApplication::platform().

This feature was funded by 3liz

This feature was developed by rldhont

Feature: GeoJSON support for WFS DescribeFeatureType

JSON support has been added as an output format for DescribeFeatureType requests to the QGIS Server WFS. Although not an explicit stipulation by the WFS specifications, this functionality allows for responses that match other WFS service providers such as GeoServer.

This feature was funded by Kristianstads kommun

This feature was developed by David Marteau


Feature: Topology checker rules enabling/disabling and filtering

The topology checker plugin has been improved to provide functionality for better management of rules, as well as filtering on large error sets. Additional enhancements bring the UX more in line with later QGIS releases and allow productivity enhancement such as bulk deletions and rule disablement.

The topology checker rules dialog now features check boxes which are attached to individual rules, which allow for enabling/ disabling rules when running validity checks without having to remove them. This avoids scenarios when users don’t want to lose rules but are only interested in validating a subset.

The topology checker panel also has a a new combo box below its toolbar to allow for quick filtering of errors to allow users to focus on a specific error type, although it will continue to display all error types by default.


This feature was developed by Mathieu Pellerin


Feature: QgsExifTools Improvements

New functionality has been added to the QgsExifTools class, including:

  • The readTag() and readTags() functions now support Xmp metadata tags

  • A new tagImage() function can be used to add individual metadata tags to a given image, which can be used in addition to the pre-existing geoTagImage() function

This feature was developed by Mathieu Pellerin

Feature: Smart bracket autocomplete updates for Code Editors

Previous releases of QGIS included an autoCloseBracket setting for the Python Console, which had a number of limitations in its behavior, including being limited to use within the Python Console and Script Editor interfaces.

Updates to the autocomplete settings extend this functionality to other Code Editor interfaces, such as the Expression Editor, Project Macro Editor, and Script Editor. The autoCloseBracket behavior has also been adjusted to better mimic the behavior of modern IDEs, and an autoSurround setting has been added to surround selected text when using the following character sets:

  • braces/ curly brackets: {}

  • square/ box brackets: []

  • parenthesis/ round brackets: ()

  • double quotation mark: "

  • single quotation mark: '

  • backticks: `

  • asterisk: *

With the exception of the backtick and asterisk characters, the autoCloseBracket functionality is available when encapsulating new data without an active text selection.

The autocompletion configuration is enabled by default for new releases, but a new settings interface is provided for granular control by users.


This feature was developed by Yoann Quenach de Quivillic

Feature: Add „toggle comment“ action to the integrated python console

The comment and uncomment actions of the embedded Python Editor have been replaced with a toggle comment action, which is now also available in the Processing Script Editor.

This brings the editor UX in line with other IDEs such as VSCode, which allow the ability to toggle comments.

The default shortcut for this action is set to Ctrl+:

The toggle comment action is also available in Project Macro and Expression Editors, however this is only available using the Ctrl+: shortcut and does not include the action button on the UI.
