 ### Changed
 
 - Upgraded Lets-Plot version to 3.0.0 (was 2.5.1).
+- Java/Swing platf.: Apache Batik upgraded to v.1.16 [[#624](https://github.com/JetBrains/lets-plot/issues/624)], [[LPK #140](https://github.com/JetBrains/lets-plot-kotlin/issues/140)].
+- The default size is increased for the plot title and decreased for the caption.
+- Upgraded Kotlin version to 1.7.21 (was 1.7.20).
 
 
 ### Fixed
 
+- Themes: can't change plot background after applying a "flavor" [[#623](https://github.com/JetBrains/lets-plot/issues/623)].
+- Layout: uneven left/right, top/bottom plot margins [[#625](https://github.com/JetBrains/lets-plot/issues/625)].
+- A plot building error with empty data on various geoms.
+- Precision error in gradient [[#634](https://github.com/JetBrains/lets-plot/issues/634)].
