Modern releases
Modern, open-source releases of the core software are here. That link leads both to source releases for users who want to build Inform at the command line, and also to ready-compiled apps.
A full version history of Inform is here, and this links to release notes showing the development of the language back to 2006.
Archive of old releases
The rest of this page archives past releases of Inform, which pre-date the open sourcing of the software in 2022. They are now only of historical use, to keep old projects working. (Note that modern versions of the apps can also use versions 9.1, 9.2 and 9.3 of the language on individual projects, but no earlier.)
