Spurious requires in DiffEqPDEBase led to most of the remaining binaries. Those were chopped.

Temporarily disables BoundaryValueDiffEq to save precompile times

This got finished, so why not. Also fixes test errors on v0.6.

It still was using `ODETestProblem`

A PyCall release made this not build correctly, at least on Windows. PyDSTool will be disabled until this is fixed.

This release adds the modeling packages DiffEqFinancial, DiffEqBiological, and MultiScaleArrays. In addition, DiffEqJump has been added for defining jump equations.

This pushes a new release for the ecosystem, and has minimum versions to match the documentation. Also updates the tests for a minor change: not a functional change, but required for the tests to pass with the newest versions of OrdinaryDiffEq.jl and StochasticDiffEq.jl.

This release marks the completion of the Runge-Kutta solvers, complete with dense output and benchmarked as highly efficient, even beating out the Hairer ODEInterface algorithms. This point, with the ODE, SDE, and basic PDE suite together marks a state of the repo which has a lar
