📌 Versioning System Explained
This mod uses a three-number version format (X.Y.Z) designed to clearly show what type of experience you’re running and how updated it is.
X — Build Edition This number represents which build of the mod you’re using. Examples include: • Immersive Build – A highly atmospheric, story-driven version • Comedy Build – A lighthearted, humorous take on the mod • Hard Difficulty Build – A challenging, intense gameplay experience
(Note: In the current release, Build 1 represents the Standard Build, which is the default experience.)
Y — Feature Update Increases when new content, mechanics, or major improvements are added to the mod.
Z — Bug Fix Update Used for small patches, fixes, optimizations, and stability improvements.
Example: 1.4.0
- 1 = Standard Build (default build)
- 4 = Fourth major feature update
- 0 = No bug-fix patches yet
This system keeps everything clean, easy to understand, and lets players instantly know which build, feature set, and patch level they’re using.
