+## Unreleased
+
+### Added
+
+- Block assembly now generalised to work with `AbstractBlockArrays`, to include changes in GridapDistributed. Since PR [939](https://github.com/gridap/Gridap.jl/pull/939).
+
 ## [0.17.19] - 2023-08-23
 
 ### Fixed
 
 - Reimplemented `DomainStyle` for `CellQuadrature` to fix breaking low-level Poisson tutorial. Since PR [#937](https://github.com/gridap/Gridap.jl/pull/937).
