Today we are shipping a coordinated security and privacy update across every supported branch of PostSharp and Metalama. It covers the build toolchain, the design-time services, telemetry, and the Visual Studio Tools. It does not change the public API or how you write aspects.
Metalama 2026.1 is now generally available, and it’s our first long-term support (LTS) release. This is a consolidation release: we finished the C# 14 work we started in 2026.0, extended the advising API, redesigned the Redis caching backend, cut several third-party dependencies, and closed most of the bug backlog.
Alongside Metalama 2026.0, we’re announcing the general availability of PostSharp 2026.0. This release brings full support for .NET 10 and C# 14, including proper handling of the new extension blocks syntax introduced in C# 14.
Metalama 2026.0 is now generally available! This major release brings full support for C# 14—the most significant evolution of the C# language in years—along with .NET 10 SDK and Visual Studio 2026 compatibility. We’re also closing one of the last feature gaps with PostSharp: the ability to override event handler invocations. And you’re getting first-class support for tuple types.
Metalama 2026.0 has reached Release Candidate status! All planned features are implemented, our test suite is green, and the release is stable enough for production evaluation. We’re now gathering community feedback ahead of our GA release on January 5th, 2026.
