What is Pyomo?

Optimization modeling library grinding through a multi-year solver-interface rewrite.

Pyomo is a Python algebraic modeling language for optimization, and its recent releases are dominated by two long-running efforts: the v2 solver interface refactor and steady expansion of the solvers it can drive. The 6.10 series dropped Python 3.9, removed the hard ply dependency, and added a Model Observer package plus gams_v2, cuopt, and scip interfaces. Release notes restate the same series highlights each time, so the actual per-release delta sits below the header block.

What is silx?

silx settles into maintenance a release after its PySide6 migration

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

Optimization modeling library grinding through a multi-year solver-interface rewrite.

◆ Current state

Pyomo is a Python algebraic modeling language for optimization, and its recent releases are dominated by two long-running efforts: the v2 solver interface refactor and steady expansion of the solvers it can drive. The 6.10 series dropped Python 3.9, removed the hard ply dependency, and added a Model Observer package plus gams_v2, cuopt, and scip interfaces. Release notes restate the same series highlights each time, so the actual per-release delta sits below the header block.

◆ Where it's heading

The center of gravity is the solver layer. Every release in this window adds or refactors an interface — KNITRO, Gurobi MINLP, cuOpt, SCIP, GAMS — while the v2 rewrite runs underneath as the eventual replacement for the legacy wrappers. Alongside that, the project is doing unglamorous modernization: pyproject.toml, NumPy 2, Python 3.14, static typing.

◆ Prediction

The v2 solver interfaces should keep absorbing solvers until the legacy wrapper can be deprecated; the entries do not show a stated timeline for that cutover.

silx settles into maintenance a release after its PySide6 migration

◆ Current state

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

◆ Where it's heading

The cadence has slowed markedly since April, and the content has shifted from structural change to plotting and colormap refinement. That is the expected shape after a binding migration: downstream beamline code needs a stable target, so the project trades feature velocity for a quiet surface. The gap between 3.0.1 in May and 3.1.0 in August is the clearest signal of the deliberate slowdown.

◆ Prediction

Expect further point releases servicing the plotting and fitting widgets rather than another structural change, with feature work continuing to arrive in the 3.1.x minors rather than patches.
