Subject: [PATCH 1/3] Update compat bounds to exclude releases >1 year old
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit updates the minimum version bounds in [compat] to exclude
package releases older than one year (as of August 2025):

- BenchmarkTools: 1 → 1.5 (v1.5.0 from Feb 2024)
- Compat: 4 → 4.15 (v4.15.0 from May 2024)
- FiniteDifferences: 0.12 → 0.12.32 (v0.12.32 from May 2024)
- OffsetArrays: 1 → 1.14 (v1.14.0 from Apr 2024)
- StaticArrays: 1 → 1.9.2 (v1.9.2 from Jan 2024)

This ensures the package depends only on recent, actively maintained
versions of its dependencies.
