+### Changed
+
+- **The default branch is now `main`**, renamed from `master`, with
+  development happening on `dev`. Existing `master` links on GitHub
+  redirect, but a local clone that tracks `master` should run
+  `git branch -m master main && git fetch && git branch -u origin/main main`.
+- **The documentation badge displays again** on GitHub and PyPI. It
+  pointed at Read the Docs' legacy badge endpoint, which rate-limits the
+  image proxies both sites fetch README images through (HTTP 429), so it
+  rendered as a broken image. It is now served through shields.io.

 ### Fixed
 
 - **The sparse solver path dropped negative modes.** Above 500 DOF a

 `pybmodes` is a pure-Python finite-element library for wind-turbine blade and tower modal analysis. It reads OpenFAST (ElastoDyn / SubDyn / HydroDyn / MoorDyn), BModes `.bmi`, and WISDEM / WindIO ontology YAML inputs; solves the coupled flap–lag–torsion–axial vibration modes with a 15-DOF Bernoulli-Euler beam element; and emits ElastoDyn-compatible mode-shape polynomials, MAC-tracked Campbell diagrams, and bundled Markdown / HTML / CSV reports.
 
-Validated against the BModes Fortran reference solver on six benchmark cases (NREL 5MW land + OC3 monopile + OC3 Hywind floating spar, IEA-3.4-130-RWT, BModes CertTest 03 / 04) to **better than 0.01 %** on every comparison. As of 1.8.0 the dedicated [Validation workflow](https://github.com/SMI-Lab-Inha/pyBModes/actions/workflows/validation.yml) (weekly cron + `workflow_dispatch`) enforces the strict tolerance in CI for the cases whose external data is clonable from a public GitHub repository **at a manifest-pinned SHA**. Cloning is manifest-driven (`verify_external_data.py --clone`), so CI fetches and `--strict`-checks every **required** entry: the NREL 5MW family in [`OpenFAST/r-test`](https://github.com/OpenFAST/r-test), all four IEA Task-37 reference turbines ([`IEA-3.4-130-RWT`](https://github.com/IEAWindTask37/IEA-3.4-130-RWT), [`IEA-10.0-198-RWT`](https://github.com/IEAWindTask37/IEA-10.0-198-RWT), [`IEA-15-240-RWT`](https://github.com/IEAWindTask37/IEA-15-240-RWT), [`IEA-22-280-RWT`](https://github.com/IEAWindTask37/IEA-22-280-RWT)), and the [`WISDEM`](https://github.com/WISDEM/WISDEM) WindIO examples — a missing or off-pin required clone hard-fails the run. Only the `optional = true` entries (MoorPy / RAFT cross-reference clones) are left out of CI as maintainer-local checks. Publishing to PyPI is itself gated on a green run of this workflow for the tagged commit. The two BModes CertTest cases (Test03, Test04) depend on `external/BModes`, a NREL download not on GitHub; those tests skip cleanly when the data is absent and stay maintainer-local enforcement. The per-PR `ci.yml` continues to run the self-contained suite (synthetic + closed-form-referenced) and tolerates "no tests collected" on the integration step when the runner has no upstream data. See [`VALIDATION.md`](VALIDATION.md) for the full per-case matrix and [`external/MANIFEST.toml`](https://github.com/SMI-Lab-Inha/pyBModes/blob/master/external/MANIFEST.toml) for the manifest-pinned commit SHAs plus line-ending-normalized SHA-256 hashes for the text validation decks.
