+### Commit 9 (2025-8-07)
+
+- Inline alloc_slice.rs
+- Improve lib.rs inlining
+- Fix formatting
+- Add some benchmarks
+- Use a build.rs to verify no UB before compiling
+- Separate `std` and `libc_std` to allow using `std` on lower versions of rust (and thus libc)
+- Comment out outdated portions of the readme
+- Add `AllocExt::alloc_guard_for`
+- Switch to manual overflow checks where necessary (using `helpers::checked_op[_panic[_const]]`)
