Maintenance activities update
------------------------------------------

Alessandro

* PR reviews
* 'gdal raster contour' half-pixel issue https://github.com/OSGeo/gdal/issues/12938


Dan

* Add "gdal vector check-geometry" and "gdal vector check-coverages" command-line utilities to check that vector features have valid/simple geometries and form a valid polygonal coverage (#12880, #12908)
* Add "gdal vector clean-coverage" command-line utility to remove gaps and overlaps from a polygon dataset (#12819)
* Add "gdal raster as-features" command-line utility to convert raster pixels into tabular features (#12970)
* Fix bounding box check in "gdal raster clip" (#12814)
* Fix invalid memory access when reading values from a raster attribute table (#12862)
* Add Python API documentation for raster attribute tables (#12863), Algorithms (#12987), and Dataset GetExtent methods (#12860)
* Improve organization of Python API documentation (#12971)
* Fix typos in documentation for pipeline substitutions (#12969)


Even

* 70+ PRs and tickets
* CLI enhancements – skip-errors
* Allow 'gdal raster info', 'gdal vector info', and 'gdal raster tile' to be last stages of pipeline
* 'gdal vector info --limit' to control output volume
* GDALG pipeline CLI substitutions – reuse the same pipeline for inputs and parameters that are substitutable during the CLI call
* Security pass to prevent relative filename traversal and injections in all drivers except VRT. There are no known exploits or reports about this, but it seems prudent to prevent.
* VSI code linting and unique_ptr usage
* 30%+ PNG tile speedup in compression scenarios
* Planning to attend the OSGeo Community Sprint in Riga

Javier

* Planning to attend the OSGeo Community Sprint in Riga

Mike Smith

* Planning to attend the OSGeo Community Sprint in Riga

Chris Toney

* gdalraster R bindings work – added new CLI bindings to R
