Release Notes

google/libphonenumber

### [`v8.12.57`](https://togithub.com/google/libphonenumber/releases/tag/v8.12.57) Hi all, Please find the new JARs on the maven site [here](https://repo1.maven.org/maven2/com/googlecode/libphonenumber/libphonenumber/8.12.57/). The new release contains mostly [metadata changes](https://togithub.com/google/libphonenumber/blob/master/FAQ.md#metadata_definition). Thanks to all those who contributed by providing issue reports! See [detailed release notes](https://togithub.com/google/libphonenumber/blob/master/release_notes.txt). **Demo Error** At this version, [demo portal's WAR file](https://repo1.maven.org/maven2/com/googlecode/libphonenumber/demo/8.12.57/) do not work when deployed in live AppEngine server, however it works when deployed and run in local AppEngine server. [This issue](https://togithub.com/google/libphonenumber/pull/2821) will be fixed soon. [Java demo portal](https://libphonenumber.appspot.com/) is still at version 8.12.57. So we recommend to use [JS demo portal](https://htmlpreview.github.io/?https://github.com/google/libphonenumber/blob/master/javascript/i18n/phonenumbers/demo-compiled.html) as new metadata updates are missing there.
