General

Custom Test Suites - You can now create custom RM Test Suites using Scenarios. This also lets you customize how reliability scores are calculated.

Parallel Scenarios - Gremlin now supports running multiple experiments in parallel within a Scenario.

CI/CD Integration - We've added CI/CD examples for running a Scenario, running an RM test, and getting an RM score using GitHub actions and Jenkins pipelines.

Improved view for Company Summary reports (previously called the Dashboard). Plan usage has been moved to Company Settings.

Scenarios can now be deleted from the Scenarios page.

Gremlin now supports delegation of Namespaces to a Team for service creation (manual and automatic)

Added Detected Risks for automatically detecting high-priority reliability concerns in a Kubernetes environment.

Launched the beta release of Failure Flags, Gremlin's new framework for running Chaos Engineering experiments on AWS Lambda functions, serverless workloads, and containers.

Added service annotations, which lets you automatically register your Kubernetes services in Gremlin by adding a simple annotation.

Added web app support for managing multiple services simultaneously. This also includes adding a Health Check to multiple services. The Services list has been reworked to reflect this change.

AWS CloudWatch Update Improved search and automated health check creation.

Label targeting support for Kubernetes in FI allows for finer grained targeting (and Service creation heuristics) based upon labels within Kubernetes in FI

Configurable Session TTL and Session Renewal Options

Fixed issue for some customers requesting shared access to new namespaces from the experiment targeting page

Fixed issue for TEAM_VIEWER role missing access on some endpoints for viewing attacks

Certificate Expiry test added to the list of available Fault Injection experiments.

Amazon CloudWatch added as an observability tool for Health Checks.

Renamed "attacks" to "experiments" (this does not change the Gremlin REST API /attacks endpoint).

Shared Health Checks - Teams can now share Health Checks with each other at the Team level, making it easier to collaborate and ensure system availability.

Datadog Health Checks - Datadog customers can now access a searchable drop-down menu of monitors, making it easier to find and select the right monitor for their needs.

Additional Providers for Network Tests - We have extended the set of network IP ranges that we are collecting, providing more comprehensive network test coverage.

Added the ability to create a service without having to add Health Checks. You will still need to add Health Checks to run reliability tests, however.

The Gremlin Kubernetes Agent now supports ARM64.

Attacks can now target Kubernetes resources with restricted network access.

Gremlin now supports targeting DeploymentConfig objects in OpenShift.

Added an overall reliability score trend line to the Company Dashboard, as well as the ability to export the Company Dashboard to PDF.

The screen shown when running a reliability test now shows a visual timeline of the test, including when health checks were performed.

"Status Checks" and "Golden Signals" have been renamed to "Health Checks".

First public release of the Gremlin Reliability Management (RM) API. Click here to see the relevant API documentation.

Made several improvements to the RM Services dashboard, including a trend line graph showing each service's reliability score over the past 30 days.

Added the ability to review and add suggested dependencies to Gremlin RM services.

Added the ability to disable API key usage at the company level.

Gremlin now supports running network attacks on multiple NICs.

Added a "Run All Tests" button to the service creation process and on the service overview page.

Added support for additional Datadog regions, specifically the EU Region.

Added the ability to flag services as Production, which adds additional warnings before you can run tests.

In Gremlin Fault Injection (FI), newly discovered agents will automatically join ongoing attacks (as long as they meet the targeting criteria).

The Getting Started page will now automatically refresh to show newly detected agents.

Added the ability to assign an owner to a service. By default, this is the user who created the service. This can be changed in the Service Settings screen.

We increased the process collection frequency for new accounts. This means new Gremlin users will no longer need to wait up to an hour before being able to create their first service.

New users can now sign up for a 30-day trial of Gremlin Reliability Management.

Added the ability to integrate with load testing tools.

Added support for integrating with Datadog's EU Region for Health Checks.

Added an in-app Getting Started page to Gremlin Reliability Management.

Process Discovery is enabled by default for new agent installations.

Added the option to Autoschedule all reliability tests.

Gremlin Reliability Management Platform released! Includes a pre-defined suite of reliability tests and service reliability scores to proactively measure reliability posture.

The Gremlin agent now supports ARM64.

A Rerun Scenario button is now available for every Scenario on the GameDay Runs tab.

Attachments on the GameDays Summary tab are now limited to 50 MiB.

GameDays are now available in Gremlin - you can perform all GameDay activities from planning, running, and sharing results in Gremlin. See GameDays Overview for more information.

Jira integration was added to Scenario Runs and GameDay Summaries. See Tracking results in Jira for details.

Updated the Gremlin Datadog integration to include Kubernetes objects for observability of Gremlin attacks in Datadog. Tags added include cluster, namespace, specific object (deployment, statefulset, replicaset, and so on), and pod name/ID.

Custom Azure tags are now supported for the Linux agent, version 2.22.5.

You can now run multiple network attacks on the same target specifying different network devices.

The Application Level Fault Injection (ALFI) feature was deprecated.

On the Attacks page, unhealthy Kubernetes pods now have a visual warning indicating that they should not be targeted. Targets containing unhealthy pods now have a visual warning as well.

Gremlin now supports network attacks for IPv6.

Error codes from killed executions are now shown on the Attack Details page.
