Mojo 1.0 Is Here

Modular has officially released Mojo 1.0, marking the language's transition to a stable, production-ready foundation. After years of rapid evolution, Mojo now offers a consistent and predictable development experience, with contributions from nearly 200 community members. This release includes Python-style lambdas, improved LSP stability, and better memory safety diagnostics. Modular also announced plans to open-source the Mojo compiler and toolchain in 2026, and introduced MAX enhancements like support for GLM-5.2 and Nemotron-H models.
Mojo 1.0 does not mark the end of the language’s evolution, but it is an important milestone on a longer journey.
