In plain English

This repository is the official home for .NET release notes and announcements. It does not contain the .NET runtime or framework source code, instead, it is a documentation and communication hub where Microsoft publishes news about .NET releases, patch notes, security advisories, and end-of-support timelines. .NET is Microsoft's open-source, cross-platform developer platform for building applications. The repository tracks which versions are currently supported: as of the README, active versions include .NET 8.0 (Long Term Support, supported until November 2026).NET 9.0 (Standard Term Support, also until November 2026), and .NET 10.0 (Long Term Support, supported until November 2028). A preview of .NET 11.0 is also listed. Long Term Support (LTS) releases receive updates and security patches for three years, while Standard Term Support (STS) releases are supported for eighteen months. You would watch this repository if you are a developer or team using .NET and want to stay informed about new releases, breaking changes, patch updates, or security vulnerabilities. The README points to GitHub Discussions as the place for news posts and announcements, with RSS feeds available to subscribe to specific categories. Actual .NET installers and binaries are downloaded from Microsoft's download site, not from this repository.
