Widen `DiffEqBase = "6.144"` → `"6.144, 7"` so ParameterizedFunctions resolves alongside the v7 OrdinaryDiffEq stack (lib/DiffEqBase 7.0.0). Version bump 5.23.0 → 5.24.0. SciMLBase `"2.15, 3.0"` already covers v3. ModelingToolkit `"11"` covers the MTK 11.22.0 compat-widened release in flight (SciML/ModelingToolkit.jl#4467). Source uses `DiffEqBase.AbstractParameterizedFunction` (still defined in lib/DiffEqBase v7 under the `@static if isdefined(SciMLBase, :AbstractParameterizedFunction)` delegation/fallback block) and nothing else from DiffEqBase. None of the symbols removed in the v7 NEWS or SciMLBase v3 breaking notes appear in `src/`: `u_modified!`, `has_destats`, `.destats`, `concrete_solve`, `fastpow`, `RECOMPILE_BY_DEFAULT`, `DEStats`, `QuadratureProblem`, `tuples()`, `intervals()`, standalone `DEAlgorithm`/`DEProblem`/`DESolution`. Not a direct blocker of OrdinaryDiffEq's own CI (ParameterizedFunctions is a test-only dep of DiffEqDevTools, not a runtime dep) — included in the same v7-compat-widening set as DiffEqCallbacks#303, DiffEqNoiseProcess#271, DiffEqProblemLibrary#182, JumpProcesses#580, ModelingToolkit#4467, StateSelection#71 so downstream users can install ParameterizedFunctions together with the v7 stack.

The DiffEqDevTools test environment failed to resolve on PR #3502 because registered versions of several test-only deps cap `DiffEqBase` at v6, while the monorepo's `[sources]` pins `DiffEqBase` to the path-sourced v7. Blockers and fixes in `lib/DiffEqDevTools/Project.toml`: - `BoundaryValueDiffEq = "5"` — registered BVDE 5.20 caps `DiffEqBase = "6.183 - 6"`. There is no BVDE release that admits DiffEqBase v7 yet, so the BVDE + `BVProblemLibrary` deps are dropped from the test env, and the single BVP benchmark block in `test/benchmark_tests.jl` is disabled with a note. - `StochasticDelayDiffEq = "1"` — registered SDDE caps `DiffEqBase` at 6 and the package is declared deprecated (see NEWS.md). Dropped; the sole SDDE test is migrated to use `DelayDiffEq` + `StochasticDiffEq` per the v7 migration guide. The SDDE branch of `analyticless_convergence_tests.jl` is commented out pending a `DelayDiffEq` dispatch for `AbstractSDDEProblem + AbstractMethodOfStepsAlgorithm` (currently only `AbstractDDEProblem` is wired through `MethodOfSteps`). - `DelayDiffEq`, `StochasticDiffEq` — registered versions cap `DiffEqBase` at 6; switched to path-sourced from `../DelayDiffEq` and `../StochasticDiffEq`. - `StochasticDiffEqCore`, `StochasticDiffEqLowOrder`, …, `ImplicitDiscreteSolve`, `OrdinaryDiffEqCore`, `OrdinaryDiffEqNonlinearSolve` — these are transitive deps of the path-sourced `StochasticDiffEq`; a sublibrary's own `[sources]` does not cascade into a downstream test sandbox, so they are added to DiffEqDevTools' `[sources]` + `[extras]` + test target to keep them on the monorepo path. - `ODEProblemLibrary = "0.1"` → `"1"`, `SDEProblemLibrary = "0.1"` → `"1"`, `OrdinaryDiffEq = "6, 7"` → `"7"` (the prior bumps from PR #3502, rolled into this PR so master also resolves). - `ParameterizedFunctions` floored to `"5.24"` (first release admitting DiffEqBase v7 per SciML/ParameterizedFunctions.jl#151). - `NonlinearSolve` floored to `"4.17.1"` (first release admitting SciMLBase v3). Test files updated for the v7-era monorepo layout where `OrdinaryDiffEq` no longer reexports every algorithm. `benchmark_tests.jl` now imports `RK4`, `Euler`, `BS3`, `Midpoint`, `BS5`, `DP5`, `Tsit5`, `Vern{6,7,9}`, `Rodas{4,5}`, `RosShamp4`, `RadauIIA5`, `DFBDF`, `NLFunctional` from their specific OrdinaryDiffEq sublibraries. `prob_func` / `output_func` signatures were updated from `(prob, i, repeat)` / `(sol, i)` to the new `(prob, ctx)` / `(sol, ctx)` SciMLBase v3 shape. An `EnsembleProblem`-based weak-convergence assertion is now `@test_broken` pending investigation of `remake(prob, seed=…)` semantics under SciMLBase v3. Local `Pkg.test()` on Julia 1.11 now reaches the full test suite — the resolve succeeds and the benchmark, ODE-appxtrue, convergence, stability and plot-recipe groups run.

Summary

DiffEqBase = "6.144"→"6.144, 7"so ParameterizedFunctions resolves alongsidelib/DiffEqBase7.0.0 (shipping with OrdinaryDiffEq v7). Bumps 5.23.0 → 5.24.0.SciMLBase = "2.15, 3.0"already covers v3.ModelingToolkit = "11"covers the MTK 11.22.0 compat-widened release in flight (SciML/ModelingToolkit.jl#4467).Why this is source-level safe

Not a direct blocker of OrdinaryDiffEq.jl#3488's own test matrix — ParameterizedFunctions is a test-only
[extras]dep of DiffEqDevTools (not a runtime[deps]), so OrdinaryDiffEq tests don't pull it in.
