***
**Interface Upgrade Summary**
* All major fund operation APIs (withdraw, borrow, liquidation, flash loan) now have corresponding \*\_v2 entry points.
* The updated function signatures feature a more complete argument list; all partner integrations should migrate to the new interfaces.
* Legacy versions WILL NOT support new reward, liquidation, flexible fee, or protected mode features.
***
#### **FAQ**
* **Q1: Is this an upgrade or a brand-new package?** **A:** This is an **upgrade to the existing major package**. Most module/method addresses will remain—watch for update notices.
* **Q2: Will borrow/liquidation interfaces remain usable?** **A:** The legacy methods will still work for non-SUI asset operations, but migration to the new entry points is strongly recommended to enjoy all new features and maximum flexibility.
* **Q3: How will the staking yield be used?** **A:** The staking yield generated from the fund manager module will be used to incentivize users in the future.
* **Q4: Is the upgrade audited?** **A:** Yes. The upgrade is fully audited by OtterSec and Movebit.
