Notes

• Bear requires Rust 1.85+ when building from source (uses the Rust 2024 edition).
• A C compiler (gcc or clang) is also required to build the preload library (libexec.so).
• Some distribution packages may lag behind the latest release. If you need v4.x features, build from source.
• For packaging-specific guidance, see the Packaging page.
