Bug in `strides` of reshaped adjoint/transposed arrays

8

Reported by @chriselrod in https://github.com/JuliaArrays/ArrayInterface.jl/pull/161#discussion_r643907939: ```julia julia> using ArrayInterface julia> A = rand(5,12); julia> B = reshape(A', (3,4,5)); julia> ArrayInterface.strides(B) # @chriselrod: should be `(5,15,StaticInt{1}())` (static(1), 3, 12) ```

Revise does not apply functions in the two-argument form of `include`

27

The two-argument form `include(mapexpr::Function, path::AbstractString)` allows transforming the code in the file at `path`. However, Revise does not seem to apply the same transformation `mapexpr` when re-loading code that is...

Option to report only summary and not every individual result for parallel runs

4

We're using GitHub actions to test our Julia project using parallel runs. We use [a setup](https://github.com/trixi-framework/Trixi.jl/blob/c635c6afb1db8b6f6cefc72d1065a111bc730081/.github/workflows/ci.yml#L125-L140) following the [parallel jobs example](https://github.com/marketplace/actions/coveralls-github-action#complete-parallel-job-example). Thus, we get many coverage reports of every individual...

This project will continue the work discussed in https://github.com/SciML/OrdinaryDiffEq.jl/issues/1423 and started in https://github.com/SciML/OrdinaryDiffEq.jl/pull/1508. The basic idea is to add fields - `stage_limiter!` - `step_limiter!` - `thread` to more/all (explicit RK)...
