### Snapshots

Snapshot builds (published from `master`) live in the Central Portal snapshots
repository, not on the main Maven Central CDN. To consume them, add that
repository alongside `mavenCentral()` and depend on a `-SNAPSHOT` version:
Snapshot builds are published from `master` and `develop` under the stable
coordinates `master-SNAPSHOT` and `develop-SNAPSHOT` — pin once and every push
to that branch republishes the same version. They live in the Central Portal
snapshots repository, not on the main Maven Central CDN. To consume them, add
that repository alongside `mavenCentral()`:

```kotlin

Gradle caches snapshot resolutions for 24 hours by default. To always pick up
the latest publish during active development:

```kotlin
configurations.all {
resolutionStrategy.cacheChangingModulesFor(0, "minutes")
}
```
