A Float32 time span could not be integrated since 0.4.2: dtmax defaults to the span length in the time type while dtmin defaulted to eps(Float64), leaving IntegratorOptions with no common type parameter. Both bounds are now converted to the node's time type at construction, with eps(T) as the floating-point default, and the struct carries no defaults of its own.

A leaf integrator built from config.values.verbose holds the splitting node's OperatorSplittingVerbosity, whose toggles are the splitting diagnostics, not the leaf's. inner_verbosity(verbose) is what init hands OrdinaryDiffEq leaves, now reachable for custom leaves.

Checklist

  • Appropriate tests were added
  • Any code changes were done in a way that does not break public API
  • All documentation related to code changes were updated
  • The new code follows the
    contributor guidelines, in particular the SciML Style Guide and
    COLPRAC.
  • Any new documentation only uses public API

A `Float32` time span could not be integrated since 0.4.2: `dtmax` defaults to the
span length in the time type while `dtmin` defaulted to `eps(Float64)`, leaving
`IntegratorOptions` with no common type parameter. Both bounds are now converted
to the node's time type at construction, with `eps(T)` as the floating-point
default, and the struct carries no defaults of its own.

A leaf integrator built from `config.values.verbose` holds the splitting node's
`OperatorSplittingVerbosity`, whose toggles are the splitting diagnostics, not
the leaf's. `inner_verbosity(verbose)` is what `init` hands OrdinaryDiffEq
leaves, now reachable for custom leaves.
