Release Notes (2.12.0)

Core Component Updates:

• Adds toxicity support in HTTP Chaos experiments. Toxicity can be used to define the percentage of HTTP requests that should be affected for example 50% toxicity will mean only half of the HTTP requests will be affected. litmuschaos/litmus-go#544

• Introduce randomized status code selection when multiple status code is provided as a fault in input for HTTP status code chaos experiment. litmuschaos/litmus-go#545

• Adds support for experiments with helper pod in chaoslib in litmus SDK with this, the user can create a chaos template with helper pod model using the same litmus SDK. litmuschaos/litmus-go#546

• Adds support for imagePullSecret in source cmd Probe this will enable the user run cmd probe pod with private image. litmuschaos/chaos-operator#415

• Fixes litmus-e2e pipeline and unit test pipeline by specifying version for creating k3s cluster. litmuschaos/litmus-e2e#391

• Fixes chaos execution on openshift-4.x by providing finalizer permission to chaos-operator service account, with the new operator upgrade in litmus 2.11.0 brings down this requirement. litmuschaos/chaos-operator#413

NOTE: - Along with above terminologies updates, we will also be updating directory structure of ChaosHub for better readability and scalability of experiments and scenarios. With upcoming release, the charts directory will be renamed to experiments directory and workflows will be renamed to scenarios directory. Same changes have been already done in 2.11.0 branch/version of ChaosHub. So, Users are requested to upgrade their ChaosHub directory structure with provided changes before upgrading to upcoming release - 2.13.0 version of ChaosCenter.
