The GOG version is up to date. It's the same version except the Epic build has a different numbering at the end,specific to the Epic version.
The Steam version's last patch dates back to 2018, while the GOG version dates back to 2020. The Epic version was released recently. That's why the numbering is different.

Many games don't have the same patch numbers across Steam, GOG, and Epic.
To identify them, you need to compare the release date of the latest Steam version with the release date of the latest GOG version.
For example, Sniper Warrior Contract 1. The Steam version is 1.09, and the GOG version is 1.08. However, both patches were released simultaneously, and the patch notes listed on GOG for version 1.08 are the same as those for version 1.09 on Steam. Therefore, you should compare the release date, not the patch numbers.
