Many instructions have deprecated v1 variants and current v2 variants. The v2 variants include support for farming rewards and improved account structure.Always use v2 variants for new integrations:
deposit_obligation_collateral_v2 instead of deposit_obligation_collateralwithdraw_obligation_collateral_v2 instead of withdraw_obligation_collateralborrow_obligation_liquidity_v2 instead of borrow_obligation_liquidityrepay_obligation_liquidity_v2 instead of repay_obligation_liquiditydeposit_reserve_liquidity_and_obligation_collateral_v2 instead of v1withdraw_obligation_collateral_and_redeem_reserve_collateral_v2 instead of v1liquidate_obligation_and_redeem_reserve_collateral_v2 instead of v1socialize_loss_v2 instead of socialize_loss
The v1 instructions are deprecated since version 1.8.0 and may be removed in future versions. Emergency Mode
Most instructions are disabled when the lending market is in emergency mode. Only administrative and refresh operations are allowed during emergency mode.
Instructions with the #[access_control(emergency_mode_disabled)] attribute will fail if the lending market’s emergency mode is enabled. Always check the market state before submitting transactions.
