Since last release we've had > 4k commits! A lot of these come from merging Envoy Mobile (https://github.com/envoyproxy/envoy-mobile) into the main Envoy repo; You can find out more about what the community has accomplished in the release notes.
As always our thanks go out to all of our wonderful users, contributors, maintainers and backporters who are helping to make Envoy such a tremendous success.
