# Lacuna PSC mobile app changelog

Mobile app versions use the format `MINOR.PATCH(.BUILD)`:

* An increment in the first number means there are new features (and possibly bug fixes)
* An increment in the second number means there are only bug fixes, with no new features

The third number is the build number. It isn't documented in this changelog, but it's shown in the app stores (usually as `1000`, which denotes the final build).
