 ### Breaking Changes
 
+## cp_amm [0.2.0]
+
+### Added
+
+- Pool now will track reserves balances `(token_a_amount, token_b_amount)` if `pool.layout_version == 1`. For pool layout_version 0, operator can call the new endpoint `fix_pool_layout_version` to pump pool version.
+- Add a new `collect_fee_mode (Compounding)`, in the new collect fee mode, fee will be collected in quote token, and a percentage of fee (configurable) will be added in reserves for compounding. In the new collect fee mode, the pool doesn't have concentrated price range, instead following constant-product formula `token_a_amount * token_b_amount = constant`.
+- Endpoints `create_config`, `initialize_customizable_pool` and `initialize_pool_with_dynamic_config` will allow user to create pool with `collect_fee_mode == Compounding`, and config for `compounding_fee_bps`.
+
+### Changed
+
+- Related to event `EvtSwap2`, in `swap_result` field, `partner_fee` will be replaced by `compounding_fee`, now total_trading_fee will be calculated as `swap_result.claiming_fee + swap_result.compounding_fee`
+
+### Removed
+
+- Removed `partner` field from Pool struct
+- Removed unused `partner_fee` feature and the `claim_partner_fee` endpoint
+
+### Breaking Changes
+
+- Quote function will be changed by the new fee mode
+
 ## cp_amm [0.1.8][PR #177](https://github.com/MeteoraAg/damm-v2/pull/177)
 
 ### Added
 
 - New endpoint `fix_pool_params` and `fix_config_fee_params` to allow `operator` to fix invalid scheduler params that causes blocking operation on `update_pool_fees` endpoint.
-- New endpoint `lock_inner_position`, that allow to vest liquidity without external `Vesting` account for better composability.
