DifferentialEquations.jl 2.0 Release: Blog Post and Breaking Changes

Hello everyone,
I am pleased to announce the release of DifferentialEquations.jl 2.0. The release notes are at the JuliaDiffEq blog:

This post details breaking changes. These were some lasting issues in the API that have been gathered over the last year and all of these changes were made in the same release. We hope by getting all of these done now (and closing all of the API related issues!), we can have a much more stable ride post-2.0. Indeed, my main goal here was to make sure that the API which will be recorded at the JuliaCon workshop will be a lasting resource for using DifferentialEquations.jl.

There will be a followup blog post explaining the state of the ecosystem with a more general overview what we have accomplished and where we are going. The sneak preview is: PDEs and stiff problems (ODEs, SDEs, DDEs, DAEs, and stiff discrete jump problems) are going to be our new best friend.
