v0.3.0

Highlights

• Error-returning APIs and operation-specific *scip.Error diagnostics, with liveness and stage guards for models and handles.
• Cancellable solves through Interrupt, SolveContext, and SolveConcurrentContext.
• Per-model log routing with SetLogFunc, SetLogWriter, and SetLogger, plus a process-global error sink.
• SCIP exact-solving support and rational solution values through Solution.ValExact and ObjValExact (*big.Rat).
• Heuristic-attributed solution constructors and Solution.Heuristic.
• Consistent plugin-family names, with deprecated aliases for older spellings, and cached callback wrappers.
• Fixed binding-owned row capture leaks, added Row.Release/TryRelease, and strengthened copied-instance identity and row-handle validation.
• In-repository guides, contributor documentation, a changelog, and runnable examples.

Migration

Custom heuristics must update Execute to receive their HeuristicPlugin as the second parameter: Execute(model, heur, timing, nodeInf). Use CreateSolFor(heur) when recording the creating heuristic on a solution.

Prefer the unified Heuristic, Separator, Nodesel, and Eventhdlr names; older exported spellings retain deprecated compatibility aliases where applicable.
