The current version of LaTeX typesetting software is LaTeX2e, which has been the standard version since 1994, with regular updates to the kernel and packages. As of 2024 to 2026, the LaTeX2e kernel is actively maintained, with latest patch releases like LaTeX2e 2024-06-01 and 2024-11-01, which include improvements and bug fixes. LaTeX3 is in development as future version, but LaTeX2e remains current production version. Distribution versions include TeX Live 2024 and 2025, and MiKTeX, which package LaTeX2e with latest packages. So when people ask current version of LaTeX, answer is LaTeX2e, with latest kernel dated 2024-06-01 or later, distributed via TeX Live 2024 or 2025. For natural latex material, there is no version, it is natural product from rubber tree, but synthetic latex versions exist. So for typesetting, current version is LaTeX2e, with ongoing updates, and LaTeX3 programming layer is available but not yet replacing LaTeX2e. You can check version by running latex --version in terminal. Most users use LaTeX2e with packages.
