The latest Rust programming langauge release enables new things to appear in ‘const fn,’ two new standard library APIs, and one feature useful for library authors.

By including the features in ‘const fn’, this led to a 40x performance improvement in Microsoft’s WinRT bindings for Rust, according to the working group behind the language.

The two new APIs that were stabilized in this release include ‘Option::zip’ and ‘vec::Drain::as_slice.’

AnalysisLevel introduced in .NET 5’s C# compiler
The new release automatically finds latent bugs in code in the new .NET 5 SDK. Before, users would need to install NuGet packages or other stand-alone tools to get more code analysis.

The AnalysisLevel in the C# compiler introduces warnings for these patterns in a safe way, according to Microsoft

In the future, Microsoft said it will add a new analysis level for every release of .NET. The goal is to make sure that a given analysis level always represents the same set of analysis defaults (the rules and their severities).
