Sourced from go.k6.io/k6's releases.

v1.2.1

k6 v1.2.1 is here 🎉! This release includes:

• Automatic extension resolution (previously Binary Provisioning) enabled for everyone
• gRPC gets better handling of NaN and Infinity float values and easier health check
• Browser module gets page.route, all the page.getBy* APIs, locator.all(), and page.waitForURL

Note: An old xk6-browser repo v1.2.0 tag was pushed by mistake. It was left over on the machine since the merging of the two repos. As such it can not be used as a go module or installed with go install. For this reason v1.2.1 is released.

Breaking changes

As per our stability guarantees, breaking changes across minor releases are allowed only for experimental features.

Breaking changes for experimental modules

• The experimental Open Telemetry and Prometheus outputs now default to TLSv1.3. This should've been the default to begin with. It is not expected that anyone should be affected, apart from making it more secure for the metrics output to send messages.

New features

Automatic extension resolution

k6 extensions allow you to add custom functionality to your tests, such as connecting to databases, message queues, or specialized networking protocols. Previously, using extensions required manual building of a custom k6 binary with the extensions compiled in. This new version introduces the Automatic Extension Resolution functionality, previously named Binary Provisioning, which is enabled by default and automatically detects when your script imports extensions and handles the complexity of provisioning the right k6 binary for you.

import faker from "k6/x/faker";
export default function () {
console.log(faker.person.firstName());
}

The previous experimental versions only supported official extensions. #4922 added the support to use any extension listed in the community list by setting the K6_ENABLE_COMMUNITY_EXTENSIONS environment variable.

K6_ENABLE_COMMUNITY_EXTENSIONS=true k6 run script.js

Note, Community extensions are only supported for local test executions (using k6 run or k6 cloud run --local-execution). When running tests on Grafana Cloud k6, only official extensions are allowed.

Check out the new extensions documentation for additional details.

Handling of NaN and Infinity float values in gRPC #4631

Previously, float values of NaN or Infinity were marshalled as null. This has now changed to use their string representation, aligning with other gRPC APIs.

There are no changes required in the scripts.
