As of today, Wolfite's Obby System is currently EOL, or End Of Life. The last update, v0.8.6, was in April of 2024. Since then, no future updates are planned, and no support will be provided on issues or bugs reguarding WOS Basic and WOS Premium.
Despite this, WOS is currently in a working state. Many similar systems are less functional and deprecated depsite not being transparent that they are.
So, should I still use it?
No one can predict the future. It is currently the 17th of August, 2025, and the system itself is far more advanced than any other available free obby system. It is also the most documented and is widely used, still. In the end, it is your decision.
