Hello all,

We've just released Consul ESM v0.4.0. It's been awhile since our last release, and we've had a large number of improvements from the community.

As always, please test in an isolated environment before upgrading. Thank you to the community for all of their contributions.

Thanks!

Hello and thank you for your email!

On June 3, 2019 HashiCorp launched Discuss, a forum to facilitate dialogue within the HashiCorp community. This format allows answers to be more readily searched and indexed, making it easier to find answers to existing questions and to share knowledge with each other.

The HashiCorp team will be shifting to interact with practitioners on the forum, and we will be phasing out the Google Groups; on September 8 at 5pm EDT, inbound messages to this group will be disabled, and it will be used for outbound announcements only.

To prepare for this switch, please direct questions and conversations to the Consul discussion forum. We look forward to collaborating with you there!
