## Releases
The EC firmware itself does not have tagged releases. Any commit of this repo
may be used as a part of a [System76 Open Firmware][firmware-open] release.
In official releases the EC shares the same version as the BIOS firmware. Run
the follow command from firmware-open to determine the corresponding EC commit
for a release.
```
git ls-tree <release_hash> ec
```
