Versioning

There are 3 different version name that you need to be aware of:

stable - This will be the most stable version of the emulator both code and cores will be tested before release. It will be updated every time a new version is released on GitHub. This is the default version on the Demo.
latest - This will contain the latest code but use the stable cores. This will be updated every time the main branch is updated.
nightly - This will contain the latest code and the latest cores. The cores will be updated every day, so this is considered alpha.

CDN

There is a new CDN that you can use to get any version of the emulator. The CDN is https://cdn.emulatorjs.org/. You can get the stable, latest, nightly, and any other main version by setting your EJS_pathtodata to https://cdn.emulatorjs.org/<version>/data/.
