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


The 3.4.0 release is a new feature release with the following highlights:

* [RFC 81](https://gdal.org/development/rfc/rfc81_coordinate_epoch.html):
   Support for coordinate epochs in geospatial formats.
   Implemented in FlatGeoBuf, GeoPackage, MEM, VRT
* New GDAL drivers:
   - [Zarr](https://gdal.org/drivers/raster/zarr.html):
     read/write support for ZarrV2 (and experimental V3), using 2D
classic raster
     API or multidimensional API:
   - [STACIT](https://gdal.org/drivers/raster/stacit.html):
