SPT follows the Semantic Versioning schema for its version numbers, which works as follows:
SPT Version X.Y.Z
X = Major update
- A large refactor of SPT or EFT
- Requires reinstalling SPT anew
- Old mods won’t work
- Old profiles won’t work
Y = Minor update
- A new version of EFT is being used
- Requires reinstalling SPT anew
- Old mods won’t work
- Some old profiles might work
Z = Patch
- Bug fixes for the previous version
- Generally doesn’t require a reinstall
- Generally works with mods made for the previous hotfix version
- Old profiles will work
- Can be used to update your SPT if it’s on the same Minor version
You can always check if a hotfix patch will be compatible with your installed mods on the Release page:

Example of the compatibility section for SPT 3.11.3.
- Download the latest SPT files from the Direct Download section at the bottom of the Release page (requires 7zip).

- Close your game, launcher, and server
- Copy contents of the 7z file into your existing folder, overwrite all files
- Update all of your mods to their latest release versions
This will only overwrite base SPT files. It will not overwrite or remove your profile(s), mods or mod configs.
