How can I find the Public Suffix List version Guava is using? Is there a command to see the version when I have the package installed? Or is there some note in the release notes I am missing?
I see that they use Mozilla Foundation's Public Suffix List but this list seems to update much more frequently than Guava releases. Does Guava pull the latest every time they do a release? This question I hope to answer once I know where to find the version.
We don't document which version we're using. But you can look at PublicSuffixPatterns at some release tag and follow the link to the commit that updated it most recently. That should tell you approximately how old the data is.
Traditionally, we updated about every 6 weeks, and the file history suggests that that's still approximately correct.
Ideally someday we'll provide a way for users to regenerate the patterns file themselves, but we haven't yet.
