On behalf of the GDAL/OGR development team and community, I am pleased to announce the release of GDAL/OGR 3.4.0. GDAL/OGR is a C++ geospatial data access library for raster and vector file formats, databases and web services.

It includes bindings for several languages, and a variety of command line

Support for coordinate epochs in geospatial formats.
Implemented in FlatGeoBuf, GeoPackage, MEM, VRT
