 ### Interfaces to other packages
-With version 0.7, the package becomes compatible with [LinearSolve.jl](https://github.com/SciML/LinearSolve.jl).
-Matrices of type `ExtendableSparseMatrix` can be passed to the `LinearProblem` constructor of [LinearSolve.jl](https://github.com/SciML/LinearSolve.jl).

+Compatibility with [LinearSolve.jl](https://github.com/SciML/LinearSolve.jl) is under development.
 
 The package provides interfaces to other sparse matrix solvers and preconditioners. Dependencies on these
 packages are handeled via [Requires.jl](https://github.com/JuliaPackaging/Requires.jl).
