 ## State
 
 From [STATUS.md](https://github.com/go-scikit/roadmap/blob/main/STATUS.md):
-the error model, the Ziv loop, roots, constants, and exp and log are done;
-trigonometric, hyperbolic and power functions are in progress. No release has
-been tagged.
+v0.1.0 is released: correctly rounded roots, exponentials and logarithms,
+trigonometric, hyperbolic and power functions and constants, and the Go oracle
+harness. Every function is at or below mpmath's time (0.18–0.97x at 53–200
+bits, 0.27–0.92x at 1000 bits;
+[docs/perf.md](https://github.com/go-bignum/bigfloat/blob/v0.1.0/docs/perf.md)),
+and the results stay correctly rounded against mpmath on 28 840 cases in six
+rounding modes.
