* Added `gdaldestroy` at exit and commented `cplseterrorhandler(C_NULL)` and trial wih `gdaldumpopendatasets` at exit * Suppressed comments in epilogue.jl * put changes into GDAL.jl, bump patch version * run gdalallregister in init Co-authored-by: Martijn Visser <[email protected]>

 Julia wrapper for [GDAL - Geospatial Data Abstraction Library](http://gdal.org/). This
 package is a binding to the C API of GDAL/OGR. It provides only a C style usage, where
-resources must be closed manually, and datasets are pointers. *Note: this also means that
-before being able to use any drivers (for input/output of different formats), they must be
-registered first using `GDAL.gdalallregister()`.*
+resources must be closed manually, and datasets are pointers.
 
 Other packages can build on top of this to provide a more Julian user experience. See for
 example [ArchGDAL.jl](https://github.com/yeesian/ArchGDAL.jl).
