 # Revision history for keel-linalg
 
-## 0.1.0.0 -- 2026-08-18
+## 0.1.1.0 -- 2026-09-03
+
+* Documentation and packaging consistency only — no library, executable or
+  test-suite code changed since 0.1.0.0.
+* The 0.1.0.0 entry below now carries the day the batch actually went out,
+  2026-08-19. The 0.1.0.0 sdist on Hackage says 2026-08-18 and is immutable,
+  so this is the first release whose shipped changelog and repository agree.
+* README: the example calls `openBackend`, binds `a` and `b`, and passes
+  `dgemm` its actual nine arguments; the umbrella subcommand is
+  `keel setup blas`; and the oracle claim now names what is checked against
+  numpy to 1e-10, what QR is gated on instead, and what is checked
+  analytically.
+
+## 0.1.0.0 -- 2026-08-19

 The backend is located by the documented keel search policy
 (`KEEL_OPENBLAS` env override, the per-user keel data dir — populated
-by `keel setup openblas` from the umbrella package — then the system
+by `keel setup blas` from the umbrella package — then the system
 search path), probed for ILP64 misconfiguration via
 `openblas_get_config`, and pinned immutably in a `Backend` handle:
 no global state, no backend swapping under a pure API.
 
-Every driver is checked against numpy/scipy oracles in the test suite
-(GEMM, LU/solve/inverse, Cholesky, QR, SVD, symmetric and general
-eigenvalues, least squares — agreement within 1e-10).
+Every driver except `ddot`, `dpotri`, `dgeqrf` and `dorgqr` is checked
+against numpy oracles in the test suite (GEMM, LU/solve/inverse,
+Cholesky, SVD, symmetric and general eigenvalues, least squares —
+agreement within 1e-10); QR is gated on orthogonality and
+reconstruction, and `ddot`/`dpotri` analytically in the smoke suite.
