[#2737](https://github.com/geodynamics/aspect/pull/2737): Unify call to visualization build\_patches() (proposed by [gassmoeller](https://github.com/gassmoeller); merged)

[#2736](https://github.com/geodynamics/aspect/pull/2736): Update dockerfile to use correct deal.II base image (proposed by [gassmoeller](https://github.com/gassmoeller); merged)

[#2735](https://github.com/geodynamics/aspect/pull/2735): Replace std::pow(x,2.0) by x\*x. (proposed by [bangerth](https://github.com/bangerth); merged)

[#2734](https://github.com/geodynamics/aspect/pull/2734): Fix the documentation of the compositional smoothing method. (proposed by [bangerth](https://github.com/bangerth); merged)

[#2733](https://github.com/geodynamics/aspect/pull/2733): Replace ‘new’ by ‘make\_shared’ where possible. (proposed by [bangerth](https://github.com/bangerth); merged)

[#2731](https://github.com/geodynamics/aspect/pull/2731): Move benchmark, add test (proposed by [gassmoeller](https://github.com/gassmoeller); merged)

[#2730](https://github.com/geodynamics/aspect/pull/2730): Add test for the named additional output postprocessor (proposed by [gassmoeller](https://github.com/gassmoeller); merged)

[#2729](https://github.com/geodynamics/aspect/pull/2729): Prefer std::make\_shared/unique over plain ‘new’. (proposed by [bangerth](https://github.com/bangerth); merged)
