# tikzphysics 1.8.0 release verification Prepared on 2026-10-11. This update includes all three previously unreleased change groups: shared piston-cylinder systems, compact percentage-anchor storage, and the fluid/element/package visual corrections. - All 16 regression suites pass, with new independent wave endpoint and annotation-font assertions. All 122 feature references are current. - All 59 example documents compile and their 160 rendered pages were reviewed across the fluid/element and expanded package audits. - Invalid geometries/indices reject with their intended diagnostics: 18 element, 16 combined fluid/element, 15 native component, 30 thermodynamic, and 18 thermal-physics cases. - All 21 isolated standalone-bundle checks pass with a five-million-word memory budget and empty user TeX tree. Recorder paths identify the bundled runtime without split physics sources. - Eighteen affected gallery pages match split/bundled raster output pixel for pixel at 72 dpi. Native patterns/fills, draw=none, dashed strokes, transformed wave attachments, and document-font inheritance were visually inspected. - The manual is 92 pages. Its changed pages were rendered and reviewed; the existing enumitem negative-labelwidth warning has no visible layout defect. - The full Overleaf archive contains 27 files; the single runtime needs no sibling physics libraries. The source archive includes complete module sources, editable manual/examples, module guides, PDF galleries, tests, helper scripts, and the LPPL 1.3c license. Evidence: `tmp/package-review-20261011/` and `tmp/release-1.8.0/`. The archive manifest and CTAN validation/upload receipts are recorded separately. CTAN submission, catalogue publication, TeX Live and standard Overleaf availability are separate states. For immediate use, upload the generated `tikzphysics.sty` beside the project's main document.
