Hi,
On behalf of the GDAL/OGR development team and community, I am pleased to announce the release of GDAL/OGR 2.2.0. 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 tools.
http://www.gdal.org/
The 2.2.0 release is a major new feature release with the following highlights:
  • New GDAL/raster drivers:
    • DERIVED driver: read-support. Expose subdatasets in a a new metadata domain, called DERIVED_SUBDATASETS
    • JP2Lura driver: read/create support for JPEG-2000 images using Luratech JP2 Library
    • PRF: add read-only support for PHOTOMOD PRF file format driver (github #173)
    • RRASTER driver: read-support .grd/.gri files handled by the R 'raster' package (#6249)
  • New OGR/vector drivers:
    • CAD driver: read support for DWG R2000 files (GSoC 2016 project)
    • DGNv8 driver: read-write support for DGN 8.0 format (using Teigha ODA libraries)
    • GMLAS driver: read-write support. XML/GML driver driven by Application Schemas.
  • New utility script: ogrmerge.py to merge several vector datasets into a single one
  • New /vsigs/ and /vsigs_streaming/ virtual file systems to read Google Cloud Storage non-public files
  • Significantly improved drivers:
    • NWT_GRD: write support (#6533)
    • FileGDB/OpenFileGDB: add support to read curve geometries (#5890)
    • VRT derived band: add the capability to define pixel functions in Python
    • Add read support for RasterLite2 coverages in SQLite driver
    • GPKG: implement tiled gridded elevation data extension
    • ISIS3: add write support and improve read support
  • RFC 63: Add GDALRasterBand::GetDataCoverageStatus() and implement it in GTiff and VRT drivers https://trac.osgeo.org/gdal/wiki/rfc63_sparse_datasets_improvements
  • RFC 64: Triangle, Polyhedral surface and TIN https://trac.osgeo.org/gdal/wiki/rfc64_triangle_polyhedralsurface_tin
    • this RFC introduces potential backward incompatible behaviour. Consult MIGRATION_GUIDE.txt
  • RFC 66: OGR random layer read/write capabilities https://trac.osgeo.org/gdal/wiki/rfc66_randomlayerreadwrite
  • RFC 67: add null field state for OGR features, in addition to unset fields https://trac.osgeo.org/gdal/wiki/rfc67_nullfieldvalues
    • this RFC introduces potential backward incompatible behaviour. Consult MIGRATION_GUIDE.txt
  • Upgrade to EPSG database v9.0 (#6772)
  • Python bindings: Global Interpreter Lock (GIL) released before entering GDAL native code (for all, in GDAL module and a few ones in ogr like ogr.Open())
  • Continued major efforts on sanitization of code base
  • Remove bridge and vb6 bindings (#6640)
  • GNM built by default
