This says updated July 1 2026, but it appears to be at least 2 years obsolete. esp32c3\_hal is replaced with esp\_hal+device feature.

Hello [Ted](https://hashnode.com/@tschundler "Ted"), that is correct. The code is obsolete and dates back to the pre-v1.0 HAL. The update date was changed by an automated process that fixed some broken links. Since the publication of _Simplified Embedded Rust_, the book has become the central source for all updates.
