Bump Julia lower bound to v1.10 and update dependencies

ChrisRackauckas · claude · ChrisRackauckas · commit 468f8a747f6b · 2025-08-09T10:24:45.000-04:00
- Update Julia lower bound from 1.6 to 1.10 - Update package dependencies to drop older lower bounds: - BenchmarkTools: 0.5 -> 1 - Compat: 3.40, 4 -> 4 - FiniteDifferences: 0.10 -> 0.12 - StaticArrays: 0.11, 0.12, 1 -> 1 - Remove VERSION checks for Julia versions < 1.10 in tests - Update CI to test on lts, 1, and pre (instead of 1 and min) - Update docs workflow to use Julia 1.10 This modernizes the package to require Julia 1.10+ which allows us to assume extensions always exist and simplify compatibility code. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
