## [Unreleased]
## [1.1.2] - 2026-05-30

**Bug-fix release: the gale-ffi i64 `SortDiffers` crash (#145).** Closes
the panic + 21 MB-stderr flood that made `loom optimize` unusable on
i64-heavy modules (gale-ffi / compiler_builtins), and width-corrects the
Z3 translation validator's i64 modeling.

### Known limitation (tracked: #147)

Verifying i64 inlining *for real* requires a Z3 bitvector solve per
function, which is **slow in aggregate** on large i64-heavy modules — so
`loom optimize` on such a module is bounded-but-slow (each query capped
by `LOOM_Z3_TIMEOUT_MS`, default 5000 ms → conservative revert on
timeout), and the i64 inline *unit tests* are `#[ignore]`'d (they hang
in SMT-formula construction, which the per-query timeout doesn't bound).
**What this release guarantees:** no crash, no stderr flood, sound output
(width-correct verification; conservative revert when a proof is slow or
unprovable). **What it does not yet guarantee:** fast, fully-verified i64
inlining on large modules. That — a cheaper i64 inline-equivalence check
and re-enabling the ignored tests — is tracked in #147. Tune with
`LOOM_Z3_TIMEOUT_MS` (lower = faster, more reverts) and
`LOOM_Z3_MAX_INSTRUCTIONS` for large i64 workloads.
