Full API Documentation

Using Guava in your project

This release will be identified in the Maven Central repository as com.google.guava:guava:13.0.1 and com.google.guava:guava-gwt:13.0.1

See UseGuavaInYourBuild for help integrating Guava into your build environment.

If you don't use managed dependencies, you can also just manually download JARs of the classes, sources and documentation from:

Note: Release 13 removes transitivity of the JSR-305 artifact (commonly used for @Nullable). Please provide your own direct dependency on this if you declare things in your own code @Nullable. More detail below.

Multisets.{contains, remove, retain}Occurrences

Tables (though newCustomTable, transformValues, and unmodifiableRowSortedTable are still @Beta)

Non-API changes

Made findbugs a provided dependency to avert dep conflicts when using findbugs 2.0. The side-effect of this change is that projects which relied upon Guava to grant access to the JSR-305 annotations "for free" will break unless they provide their own direct dependency on that jar (or an equivalent). Projects should always have been directly depending on JSR-305 (per maven best-practice), but this change makes that should into a must.

Caliper benchmarks for much of Guava have been open-sourced.

LinkedHashMultimap has been entirely rewritten, reducing its memory consumption by ~50%. (Previously, it was one of the worst potential memory hogs in the library.)

ImmutableSortedMultiset has been rewritten, reducing its memory consumption by ~40%.

ImmutableSortedMap has been rewritten, reducing its memory usage by ~50%.

Fixed a significant performance regression in LocalCache (12.0 was affected, but 12.0.1 was not)
