This release brings many new features, while aiming to make TypeScript smaller, simpler, and faster. We’ve implemented the new decorators standard, added functionality to better support ESM projects in Node and bundlers, provided new ways for library authors to control generic inference, expanded our JSDoc functionality, simplified configuration, and made many other improvements.

Why Serilog? It is easy to set up, has a clean API, and is portable between recent .NET platforms. The big difference between Serilog and the other frameworks is that it is designed to do structured logging out of the box. Another thing I really like about Serilog is that it can be configured via the appsetting.json
file alongside configuring through code. Changing logging configuration without touching the codebase is really helpful, especially in the production environment.

Some months ago a feature landed in Xamarin.Forms that seemed to truly polarize the Xamarin.Forms community: support for styling applications using CSS. Some argued that it was an unnecessary introduction to "Web" technology to the native development experience, and others that it simply isn't the right solution to the problem. While I sympathize with the latter opinion and think there's plenty of room for some good debate on the right path forward, I count myself as part of a third camp: I think that CSS is a powerful (and frequently maligned) solution to the problem of styling native mobile applications.
