While CVE-2020-8908 was officially closed when we deprecated Files.createTempDir in Guava 30.0, we've heard from users that even recent versions of Guava have been listed as vulnerable in other databases of security vulnerabilities. In response, we've reimplemented the method (and the very rarely used FileBackedOutputStream class, which had a similar issue) to eliminate the insecure behavior entirely. This change could technically affect users in a number of different ways (discussed under "Incompatible changes" below), but in practice, the only problem users are likely to encounter is with Windows. If you are using those APIs under Windows, you should skip 32.0.0 and go straight to 32.0.1 which fixes the problem. (Unfortunately, we didn't think of the Windows problem until after the release. And while we warn that common.io in particular may not work under Windows, we didn't intend to regress support.) Sorry for the trouble.
Incompatible changes
Although this release bumps Guava's major version number, it makes no binary-incompatible changes to the guava artifact.
One change could cause issues for Widows users, and a few other changes could cause issues for users in more usual situations:
The new implementations of Files.createTempDir and FileBackedOutputStreamthrow an exception under Windows. This is fixed in 32.0.1. Sorry for the trouble.
This release makes a binary-incompatible change to a @Beta API in the separate artifactguava-testlib. Specifically, we changed the return type of TestingExecutors.sameThreadScheduledExecutor to ListeningScheduledExecutorService. The old return type was a package-private class, which caused the Kotlin compiler to produce warnings. (dafaa3e435)
