Prompt: Lets prepare the next release of specsolve.

Note

The following content was generated by AI.

Releases 0.9.1 on merge: two engine fixes (#2028, #2029), parquet sources read at once (#2014), and the rebuilt benchmarks page. A patch release, because nothing since v0.9.0 breaks a model file or an import.

How the notes were edited, and what was checked

• The ## Upcoming version lines are grouped into Fixes, Speed, The benchmarks page and Other docs. A new, empty ## Upcoming version sits above the release.
• Merged lines: the four re-measurements (docs(benchmarks): the published benchmarks are re-measured with the network and sparse models, down to a few hundred variables #2005, docs(benchmarks): the published benchmarks are re-measured with the sector-coupled model #2024, docs(benchmarks): the published benchmarks are re-measured with the network model's pooled plants #2031, docs(benchmarks): the published benchmarks are re-measured at the new model sizes, five times each tenfold step #2039) are one line; the two axis and zoom lines (docs(benchmarks): the benchmark charts share one pair of axes across every model, and a box dragged on any chart zooms all of them #2040, docs(benchmarks): the benchmark charts zoom to a range of model sizes, on log and linear axes #1993) are one line; the two polars-thread guide lines (docs(howto): the guide to faster solves says that a small model builds faster on one polars thread, and times it when the page is built #2016, docs(howto): the guide to faster solves gives the gain from one polars thread as a rough estimate, and tells the reader to time their own model #2017) are one line.
• Every PR linked under the old ## Upcoming version is linked in the notes, and no other PR is (compared by script).
• python -m tools.changelog check: "releases 0.9.1 on merge". python -m tools.changelog notes 0.9.1 prints the section.
• src/ since v0.9.0 is the three PRs above: 2 files, +44/−11. None changes a public name or what a file accepts.
• Not run: pixi run check. This PR changes only CHANGELOG.md.

The published benchmarks on main were measured at fbc735a, a dev build. To make the page name a release, the published benchmark should run on main right after this merges and v0.9.1 is tagged.

Footnotes

1. 307 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (15f298d) during the generation of this report, so 2588883 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
