The Xen Project announced the latest version of its open-source hypervisor. Xen Project Hypervisor 4.14 introduces Linux subdomains, better nested performance, more robust live patching and reflects contributions from across the community and ecosystem. 

A new development made in the Xen Project Functional Safety Working group is the successful drafting of prototype requirement documents and progress towards the processes and procedures on maintaining these documents. 

Ongoing work on the project includes Secret free Xen which will prevent memory from being mapped, Golang bindings significantly expanded, and live migration without need for guest cooperation.

Apollo Client 3.0 released
The new release includes a single, consolidated ‘@apollo/client’ package, new ‘InMemoryCache APIs,’ improved local state management APIs, expanded and refined UI reactivity, and extensive internal refactoring. 

By caching data from the user’s server,  Apollo Client locally reconstructs a subset of the back-end data graph. The next time Apollo Client queries some of that same data, it can fetch it directly from the cache, even if an entirely different query requests it. 

The majority of 2.x functionality remains in 3.0. The full list of details on the new release is available here.
