 ### Features
 
 - Added an incompressible SPH solver `ImplicitIncompressibleSPHSystem` (#751).
+- Added `SplitIntegrationCallback` to integrate the `TotalLagrangianSPHSystem`s
+  in a `Semidiscretization` separately from the other systems (#794).
 
+### Important Bugfixes
 
+- Fixed `kernel_grad` threshold with single precision and small particle spacing (#913).
+- Fixed error with `UpdateCallback` when `SaveSolutionCallback` comes first in the
+  `CallbackSet` (#924).
+- Fixed error when using shifting techniques without `UpdateCallback` (#925).
+- Updated program flow diagram (#917).
