v4.15.0

[4.15.0] - 2026-06-30

This release is 100% compatible with Lets-Plot v 4.11.0,
GeoTools v 33.2

Added

• theme(): new tooltipMerge and tooltipMaxCount parameters to combine the general tooltips of multiple targets into a single tooltip.

  See: example notebook.

• Text halos improve readability on varied backgrounds. New haloWidth and haloColor parameters are supported in geomText()/geomTextRepel() and by labels in corrPlot().

  See: example notebook.

• SpatialDataset objects can be displayed as compact preview tables in Kotlin notebooks [LPK-274].

  See: example notebook.

Fixed

• Incorrect hjust/vjust/angle justification of vertical-axis tick labels (theme(axisTextY=elementText(...))).
• Rotated vertical-axis tick labels could be wrongly dropped or kept by overlap-based break filtering.
• Misaligned or mismatched axis tick labels when some breaks are dropped after layout.
