Version 1.12.0
This release includes many breaking changes to the metrics SDK as we move towards marking its first stable release.
Notably, if you configure metric View
s or have written a custom metric exporter, many of the classes and methods will
have been moved or renamed. There are still a few remaining cleanups targeted for the next release after which there
should not be many. Thanks for bearing with us on this.
