because we lack QGIS expression support for DateTime literals, we currently rely on the "to_datetime" expression function and coerce everything through strings. The beauty of feature request expression compilation should mean that the QGIS expressions are magically turned into native backend queries, BUUUUUUUUUUUT. we don't need to worry about the different SQL syntaxes used natively by the different providers). This is intentional because it provides a unified filter approach regardless of the provider used (i.e. Unlike the Time Manager plugin approach, the approach taken here is to rely completely on QGIS expressions and feature requests to do the filtering (Time Manager uses layer filter strings and attempts to set a native SQL filter syntax so that filtering is done on the backend).In future, we should allow selection of string fields and allow users to enter a custom DateTime format string This was done to simplify the format handling and avoid the need to worry about string fields with different DateTime formats.

Sponsoring QGIS helps us to fund our regular developer meetings, maintain project infrastructure, and fund bug fixing efforts. If you would like to become an official project sustaining member, please visit our sustaining member page for details. A current list of donors who have made financial contributions large and small to the project can be seen on our donors list. QGIS is supported by donors and sustaining members. From the QGIS community, we hope you enjoy this release! If you wish to donate time, money, or otherwise get involved in making QGIS more awesome, please wander along to QGIS.ORG and lend a hand! We would like to thank the developers, documenters, testers, and all the many folks out there who volunteer their time and effort (or fund people to do so). Users focussed on cartography and digitising haven't been left out either, with many new options for you! Some of the marquee features include vector tile support, huge advances in mdal / mesh support, native support for temporal data in WMS-T, PG Raster, vector providers, and mesh layers. This release is so jam-packed with new features and improvements big and small, it is hard to know where to start. Another awesome release in the trail of great QGIS releases we have made across 18 years of development.
