Dotty 0.2.0-RC1 Released

On Wednesday, July 12th, Dmitry Petrashko announced the latest release candidate for Dotty.

According to the announcement, the preview is focused on improving stability and reliabiliity, and adding IDE support. Some of the changes include:

  • #2829 - Adds pattern matcher optimizations
  • #2676 - Faster base class sets
  • #2742 - Handle wildcard types in unions and intersections
  • #2722 - Fixes hover functionality for enum classes
  • #2739 - Fixes shadowing for higher order implicits

Head over to Scastie to test the preview out without having to download anything. (Psst, did you know that 47 Degrees worked on the UI design of Scastie?!?)

Kubernetes 1.7 GKE

The latest release of Kubernetes is now available on Google Container Engine. Version 1.7 is designed, in conjunction with GKE, for increased enterprise security, extensibility, hybrid networking, and improved developer efficiency, according to the announcement.

Improved workload isolation was a big focus with features like Node authorizer restricting kubelet’s API access, network isolation through the Kubernetes NetworkPolicy API, and HTTP re-encryption through Google Cloud Load Balancing.

The release also comes with expanded global availability in new GCP regions, among many other features.
