10.10.0 (2026-08-28)
Another big release with lots of great new features (RTL support, Variable Row Height, multi-range cell/row selections, better auto-scroll and most importantly Row Detail and RowSpan are now both working with row 'transform' top offset). There's also a lot of fixes, see the long list below in which AI was definitely helpful with :)
Note
Row Detail and RowSpan now work with rowTopOffsetRenderType: 'transform' (better perf on large dataset), however in the case of Row Detail it is only available by adding another new grid option rowDetailView.renderMode: 'overlay' in combo with 'transform'. More importantly rowTopOffsetRenderType is no longer needed and is now Deprecated and the grid option will be removed in the next v11 major version (in 2027 Q1) and in terms the 'overlay' will become the new and only default in v11 (even the 'overlay' is temporary and will also be removed in v11).
For more detail, see Row Detail docs and RowSpan docs
