# Changelog

## 0.1.0 (2026-10-23)

The first release: an EtherCAT MainDevice that scans a segment, reads the SubDevices' SII, takes
them through the AL state machine, transfers CoE SDOs through their mailboxes, maps their PDOs into
one process image with FMMUs, and exchanges it when the application asks, over raw Ethernet on Linux
and macOS or over UDP. On a ring back to a second port, it goes on through a broken cable. Nothing
logs.
