## Snapshots and Documentation

Snapshots of Guava built from the `master` branch are available through Maven
using version `999.0.0-HEAD-jre-SNAPSHOT`, or `999.0.0-HEAD-android-SNAPSHOT`
for the Android flavor.

[Snapshot API Javadoc][guava-snapshot-api-docs] as well as
[Snapshot API Diffs][guava-snapshot-api-diffs] are also available.

Another easy way to get to the Javadoc is to open

   * exceptions.
   *
   * **The caller must [close][Snapshot.close]** each snapshot returned by [Iterator.next]. Failing
   * to do so leaks open files!
   */
