## 0.54.0

### Major Changes
* We added support for slices in the `#[kani::modifies(...)]` clauses
when using function contracts.
* We introduce an `#[safety_constraint(...)]` attribute helper for the
`Arbitrary` and `Invariant` macros.
* We enabled support for concrete playback for harness that contains
stubs or function contracts.
* We added support for log2*, log10*, powif*, fma*, and sqrt*
intrisincs.

### Breaking Changes
* The `-Z ptr-to-ref-cast-checks` option has been removed, and pointer
validity checks when casting raw pointers to references are now run by
default.
