feral v0.5.0 (2026-05-22)

First tagged release. Sparse symmetric indefinite direct solver in
pure Rust with certified inertia counts.

Highlights since 0.4.0:

  • Added: value-bounded MC64 scaling cache; near-singularity signal.
  • Changed: inertia counts every pivot by sign; oracle-consensus parity.
  • Performance: Schur trailing-update kernel widened (quad NEON-tile).
  • Fixed: 8 correctness/robustness fixes across scaling, inertia, and
    delayed-pivot handling (#39, #45, #46, #47, #48, #49).

See CHANGELOG.md [0.5.0] for the full list.
