Grafana v6.6 Released

Grafana 6.6 introduces a range of new features and improvements across various components such as Alerting, Explore, Loki, and CloudWatch. Key updates include the introduction of a new Stat panel designed to replace the Singlestat panel, enhanced alerting configurations to reduce backend load, and design updates to the TimePicker for improved usability. The release also adds support for custom data units, allowing users to personalize unit displays on panels, and introduces white labeling options in the enterprise version for greater customization. Additional enhancements in Explore include log message line wrapping, unique log labels, and a context tooltip for better data query refinement. The update also includes changes to cookie management to align with Chrome 80's SameSite attribute modifications and improvements in CloudWatch for automatic period calculation based on time range, reducing the risk of exceeding data point limits. The release encourages users to upgrade to the Enterprise Edition for seamless updates and highlights ongoing efforts to transition from AngularJS to React, which may affect plugin behavior.
