• BUG: Set sampling percentage and strategy for SyN by @ntustison in https://github.com/ANTsX/ANTs/commit/14e7312928179387e74a941f4b48223ffb9f4052
• ENH: Set ITK version to 5.3.0 by @cookpa in https://github.com/ANTsX/ANTs/pull/1477

Note about the sampling strategy in SyN: this release allows sparse metric sampling in SyN, eg you can use Regular or Random sampling in the metric. Previously, these options were silently ignored for SyN (but not for other transforms). However, user-defined random seeds are not used in SyN and BSplineSyN. Fixing this required an ITK change and will be resolved in the next release. The default in all ANTs scripts is to use dense sampling in SyN / BSplineSyN, which are not affected.
