  • Add 'gdal raster nodata-to-alpha' (#12524)
  • Add 'gdal raster pansharpen' (port of gdal_pansharpen.py)
  • Add 'gdal raster proximity' (#12350)
  • Add 'gdal raster rgb-to-palette' (port of rgb2pct.py)
  • Add 'gdal raster update'
  • Add 'gdal raster zonal-stats'
  • Add 'gdal vector check-coverage'
  • Add 'gdal vector check-geometry'
  • Add 'gdal vector clean-coverage'
  • Add 'gdal vector index' (port of ogrtindex)
  • Add 'gdal vector layer-algebra' (port of ogr_layer_algebra.py)
  • Add 'gdal vector make-point'
  • Add 'gdal vector partition'
  • Add 'gdal vector set-field-type'
  • Add 'gdal vector simplify-coverage'
  • Add 'gdal mdim mosaic' (#13208)
  • Add 'gdal dataset' port of 'gdal manage'
  • gdal vector pipeline: add limit step
  • Make 'gdal pipeline' support mixed raster/vector pipelines
  • Pipeline: add support for nested pipeline (#12874)
  • Pipeline: add support for a 'tee' step (#12874)
  • Move 'gdal vector geom XXXX' utilities directly under 'gdal vector'
  • Rename 'gdal vector geom set-type' as 'gdal vector set-geom-type'
  • gdal raster reproject: add a -j/--num-threads option and default to ALL_CPUS
  • Make 'gdal raster fill-nodata/proximity/sieve/viewshed' pipeline-able
  • gdal raster mosaic/stack: allow it to be the first step of a raster pipeline
  • gdal pipeline: allow to run an existing pipeline and override/add parameters
  • Improved Bash completion
  • Python bindings: add a dynamically generated 'gdal.alg' module
    (e.g. gdal.alg.raster.convert(input="in.tif", output="out.tif"))
  • Many other improvements to existing utilities (see below)

• VRT pixel functions: Add mean, median, geometric_mean, harmonic_mean, mode
  (#12418), and handle NoData values

• Add C/C++/Python API for raster band algebra:
  arithmetic operators, comparison operators, AsType(),
  gdal::abs()/sqrt()/log10()/log()/min()/max()/mean()/IfThenElse() functions

• Add MiraMon raster driver: read-only support (#12293)

• ADBC driver: support for ADBC BigQuery driver (requires BigQuery ADBC driver)

• JSONFG driver: add read/write support for curve and measured geometries;
  update to 0.3.0 spec

• Parquet: add update support using OGREditableLayer mechanism

• Add C++ public header files for raster functionality

• Security: avoid potential path traversal in several drivers

• Various code linting, static code analyzer fixes, etc.

• Significant automation of the release process

• Add Docker attestation (#13066)

• Bump of shared lib major version
