​
Ensured devDependencies are not installed in the agent image

  • Added support for a dev image including build tools to support building native npm packages
  • Improved internal logging and metrics for Playwright Check Suites

​
Added Checkly environment variables and configuration to Playwright Check Suites. See the docs on Playwright Check Suites environment variables:

Minor patches on reporting
​
Improved and centralized secret scrubbing for more reliable removal of sensitive data
