Three Versions of Open Rails

Three versions of Open Rails are readily available to users, as shown below:

For first-time users, we recommend the Stable Version which comes with an installer.

Updater

Whichever version you choose, Open Rails has a mechanism to notify you of new versions and to update Open Rails for you. You will find the settings for this mechanism in Menu > Options > Update

Open Rails will check for updates at most once a day. If an update is found, then you can install the update just by clicking on the link in the top, right corner:

Testing Version

If you follow the Open Rails project on the forums, then you will hear about bug-fixes and new features. These are included in the Unstable Version for developers and testers to try out. Once they have been checked and approved, they are published (on Friday) as the latest Testing Version. Any user can easily update to the current weekly Testing Version and benefit from these improvements.

For reference all the Testing Versions (executable and source) can be found in our archive.

Unstable Version

To support development, the latest unstable version is also available, which is updated whenever a developer publishes a change. The unstable versions are more likely to contain serious bugs and are only recommended for users wishing to help with Open Rails development.

The Manual for the Unstable version is not included in the download, but is available on-line.

For reference all the Unstable Versions (executable and source) can be found in our Unstable archive.
