EnzymeCore was listed in [deps] but never imported or used in any source file. Having it as a strong dependency forces it to be installed transitively for all DiffEqBase users, which triggers the OrdinaryDiffEqCoreEnzymeCoreExt extension unconditionally. Combined with the always-available SparseArrays stdlib triggering OrdinaryDiffEqCoreSparseArraysExt, this causes a circular dependency error during precompilation on Julia 1.10.

Summary
EnzymeCorefrom[deps]— it was never imported or used in any source file[compat]entry forEnzymeCoreMotivation
EnzymeCore as a strong dependency forces it to be installed for all DiffEqBase users. This causes OrdinaryDiffEqCore's
EnzymeCoreExtextension to trigger unconditionally. Combined with the always-availableSparseArraysstdlib triggeringSparseArraysExt, Julia 1.10's precompilation system detects a circular dependency between the two extensions, preventing precompilation and causing errors when loading with EnzymeCore.See SciML/OrdinaryDiffEq.jl#3025
