Master for Ordinary/Stochastic/Delay already did this change. dtcache is only used for fixed timesteps, and the caches that use dt are only fixed as well (because they stash something based on dt) so I don't believe the is an issue. dtproposed gets overwritten before it's used.

But I can't see this change in DelayDiffEq... But it seems moving https://github.com/JuliaDiffEq/DelayDiffEq.jl/blob/master/src/solve.jl#L122-L135 down is the only change that is required.

Oh I thought handling it just from OrdinaryDiffEq was all that was required since that's what sets dt. This might need a fix like you mention. I only tested it well on ODEs and SDEs, and haven't added unit tests yet. Tests on DDEs will probably show that needs to be moved...

This is being addressed in #49, but just doubles the calculation.
