Widen compat so LSODA.jl resolves alongside the v7 OrdinaryDiffEq stack (lib/DiffEqBase 7.0.0, SciMLBase 3): - DiffEqBase: "6" → "6, 7" - SciMLBase: "1.80, 2" → "1.80, 2, 3" Version bump 0.7.6 → 0.7.7. Source uses a small, stable DiffEqBase / SciMLBase surface: - `DiffEqBase.AbstractODEAlgorithm` (`src/LSODA.jl:19`) - `SciMLBase.alg_order` (`src/LSODA.jl:21`) - `DiffEqBase.__solve`, `DiffEqBase.AbstractODEProblem`, `DiffEqBase.AbstractParameterizedFunction`, `DiffEqBase.has_tgrad`, `DiffEqBase.has_jac`, `DiffEqBase.build_solution` (`src/common.jl`) All of these remain in lib/DiffEqBase v7 and SciMLBase v3 unchanged. Grepped `src/` clean for every symbol removed in the v7 NEWS / SciMLBase v3 breaking notes: `u_modified!`, `has_destats`, `.destats`, `concrete_solve`, `fastpow`, `RECOMPILE_BY_DEFAULT`, `DEStats`, `QuadratureProblem`, `tuples()`/`intervals()`, standalone `DEAlgorithm`/`DEProblem`/`DESolution`.

Summary
Widen compat so LSODA.jl resolves alongside the v7 OrdinaryDiffEq stack (lib/DiffEqBase 7.0.0, SciMLBase 3):
DiffEqBase: "6"→"6, 7"SciMLBase: "1.80, 2"→"1.80, 2, 3"Version bump 0.7.6 → 0.7.7.
Why this is source-level safe
LSODA.jl's DiffEqBase / SciMLBase surface is small and entirely stable across the v7/v3 rename:
DiffEqBase.AbstractODEAlgorithm(src/LSODA.jl:19)SciMLBase.alg_order(src/LSODA.jl:21)DiffEqBase.__solve,DiffEqBase.AbstractODEProblem,DiffEqBase.AbstractParameterizedFunction,DiffEqBase.has_tgrad,DiffEqBase.has_jac,DiffEqBase.build_solution(src/common.jl)All of these remain in lib/DiffEqBase v7 and SciMLBase v3 unchanged (verified against
lib/DiffEqBase/src/DiffEqBase.jlin SciML/OrdinaryDiffEq.jl master).Grepped
src/clean for every symbol removed in the v7 NEWS / SciMLBase v3 breaking notes:u_modified!,has_destats,.destats,concrete_solve,fastpow,RECOMPILE_BY_DEFAULT,DEStats,QuadratureProblem,tuples()/intervals(), standaloneDEAlgorithm/DEProblem/DESolution. Zero matches.Motivation
OrdinaryDiffEq.jl is preparing a v7 release that bumps DiffEqBase to v7 and SciMLBase to v3. SciML/OrdinaryDiffEq.jl#3488 is the integration branch. LSODA.jl's current
DiffEqBase = "6"/SciMLBase = "1.80, 2"cap prevents it from being installed alongside the v7 stack —Pkgwould reportUnsatisfiable requirements detected for package LSODA. This PR widens that cap.Scope
