-## Key documentation for mathematical context
+## Release state
 
-When working on math-heavy tasks, read these before reasoning from scratch:
+Current release: **v0.7.0** (tag on `origin/dev`, PR to `main` open).  
+Phase 7 is complete. Phase 8 (CGAL package) is next.
+
+Root-level files added at v0.7.0:
+- `CITATION.cff` — machine-readable citation (Sechelmann 2016, Springborn 2020, Bobenko–Springborn 2004)
+- `CONTRIBUTING.md` — short root-level pointer to `doc/contributing.md`
+- `scripts/try_it.sh` — one-script quickstart: build → 209 tests → example run
+- CMake install target: `cmake --install build --prefix /usr/local` → headers land in `include/conformallab/`

+### geometry-central context
 
 **geometry-central** (Keenan Crane, CMU) implements the same discrete conformal
 equivalence problem (Gillespie, Springborn & Crane, SIGGRAPH 2021) but uses
 Ptolemaic flips on intrinsic triangulations instead of Newton on the original mesh.
 It has no period matrix, holonomy, or spherical geometry mode.
 The shared mathematical core (Springborn 2020) means cross-validation is meaningful.
-See `doc/architecture/geometry-central-comparison.md` for the full comparison.
+Full analysis: `doc/architecture/geometry-central-comparison.md`.
+Optional adoption roadmap (GC-1/2/3): `doc/roadmap/phases.md` (Optional section).
