+## v2.2.0 - Neutron Perps release
+
+### Perps Integration
+- Added new `perps` contract with perps functionality integrated into Credit Manager
+
+### Credit Manager Enhancements
+- Integrated perps positions as account collateral, with direct impact on account Health Factor
+- Implemented flexible loss settlement mechanism for perps:
+  - First attempts to deduct from existing deposits
+  - If deposits are insufficient, will unlock lending positions
+  - As a last resort, will borrow the required USDC amount
+
+#### New Execute Messages
+- Added execute messages:
+  - `UpdateBalanceAfterDeleverage`
+  - `ExecuteTriggerOrder`
+
+#### New Actions
+- Introduced new actions:
+  - `DepositToPerpVault`
+  - `UnlockFromPerpVault`
+  - `WithdrawFromPerpVault`
+  - `CreateTriggerOrder`
+  - `DeleteTriggerOrder`
+  - `ExecutePerpOrder`
+
+#### New Queries
+- Added queries:
+  - `AllAccountTriggerOrders`
+  - `AllTriggerOrders`
+- Updated `Positions` query to include perps positions
+
+#### Positions Struct Update
+```diff
+pub struct Positions {
+    pub account_id: String,
+    pub account_kind: AccountKind,
+    pub deposits: Vec<Coin>,
+    pub debts: Vec<DebtAmount>,
+    pub lends: Vec<Coin>,
+    pub vaults: Vec<VaultPosition>,
+    pub staked_astro_lps: Vec<Coin>,
++   pub perps: Vec<PerpPosition>, // New field
+}
+```
+
+### Liquidation Mechanism
+#### Perps Liquidation
+- Implemented comprehensive perps liquidation process:
+  - When an account becomes liquidatable, perps positions are closed first
+  - Normal liquidation executes after perps closure
+  - If closing perps is sufficient to restore account health, liquidator receives a bonus
+- Liquidation bonus calculation:
+  - Uses the same bonus mechanism as general liquidation (based on Health Factor)
+  - Bonus specifically reduced to 60% to prevent over-rewarding
+  - Added `perps_liquidation_bonus_ratio` to Credit Manager configuration
+- Special liquidation scenario:
+  - Liquidation possible even when no spot debt exists
+  - Triggered if perps positions could potentially bring account Health Factor below 1
+  - Allows liquidator to close perps at a loss without additional debt repayment
+
+#### Liquidation Changes
+- Simplified liquidation mechanism by changing to static close factor
+- Removed Max Debt Repayable (MDR) formula for dynamic bonus calculation in Credit Manager and Red Bank
+
+### Health Calculations
+- Health Contract now includes calculations based on perps positions
+- Returns additional perp loss and profit information
+- Removed `kind` from health-related queries
+- HealthComputer integrated into CreditManager to reduce gas consumption
+
+#### Health Struct Update
+```diff
+pub struct Health {
+    pub total_debt_value: Uint128,
+    pub total_collateral_value: Uint128,
+    pub max_ltv_adjusted_collateral: Uint128,

++   pub has_perps: bool,                  // New field
+}
+```
+
+### Oracle and Pricing
+- Introduced Slinky oracle price support for perps
+- Added new Oracle contract query for prices by denoms
+
+### Incentives Contract

 ## v1.2.0
