AtomVM Daily: Weekly Recap - Hardening the Runtime, Filling in the Standard Library
Nineteen pull requests landed this week, most of them safety fixes across the JIT, networking, and device drivers, alongside steady progress filling out missing Erlang standard library functions. The pattern is consolidation: AtomVM is closing correctness gaps rather than chasing new features.

This is AtomVM Daily for the week of July 20th through July 27th. Nineteen pull request activity items, zero additional commits this week.
The strongest signal this week: this was a hardening cycle. A large share of merged work fixed cases where bad or unexpected input could crash the runtime or silently produce wrong results, rather than adding new capability.
Start with correctness fixes at the term and bit-syntax level. Bettio's PR 2380 fixed a 32-bit build bug where oversized integers were silently truncated instead of raising an error, affecting checksum and crypto functions. Pguyot's PR 2377 closed a related hole where negative dynamic segment sizes in bit syntax…
Driver and platform safety was the second theme. PR 2363 validates USB serial port requests before dispatch, closing a path where a malformed term could be dereferenced as a pointer. PR 2362 bounds a UART read call that previously had no limit. PR 2370 changes ESP32 WiFi power-save behavior by default, trading…
Third, standard library completeness. Bettio's PR 2374 finally lands process_info/1 and the list-argument form of process_info/2, matching Erlang/OTP behavior and needed by the Popcorn project — this revives a…
