​

What To Do

​

Program: lb_clmm 0.12.0

​

Added

• New endpoint add_liquidity_by_weight2, that is same as add_liquidity_by_weight but supports token2022
• New endpoint set_permissionless_operation_bits to allow position owner to enable permissionless authorization on some operations such as claim_fee
• New endpoint place_limit_order to allow user to place limit orders for either bid or ask side.
• New endpoint cancel_limit_order to cancel limit order.
• New endpoint close_limit_order_if_empty to close a limit order if it’s empty.
• New endpoint close_bin_array to close an invalid bin array.
• Account PresetParameter added new collect_fee_mode field. All the existing PresetParameter account will have default CollectFeeMode::OnlyInput.
• Account LbPair::StaticParameters added new collect_fee_mode field. All existing LbPair account will have default CollectFeeMode::OnlyInput.

​

Changed

• Allow permissionless claim_fee if position owner enabled it
• All the existing LbPair accounts without any liquidity mining rewards will be defaulted to limit order supported pool and doesn’t support LM anymore. This is not revert-able.
• Updated initialize_permissioned_lb_pair parameter InitPermissionPairIx field protocol_share to padding0 because it was no longer in use
• Endpoint go_to_a_bin will revert if the pool is disabled / before activation. The restriction can be bypassed by operator by passing operator associated accounts through remaining accounts.

​

Removed

• Remove endpoint reset_pool_tombstone_fields, reset_bin_array_tombstone_fields, reset_position_tombstone_fields

​

Breaking Changes

• Endpoint initialize_preset_parameter added new collect_fee_mode field.
• Endpoint initialize_preset_parameter field function_type enum type has been changed to concrete_function_type.
• Enum FunctionType no longer defaulted to FunctionType::LiquidityMining. All existing on chain LbPair account will defaulted to FunctionType::Undetermined. With FunctionType::Undetermined, if there’s liquidity reward initialized, it will be FunctionType::LiquidityMining, else will be FunctionType::LimitOrder
• Swap quote mechanism due to introducing of collect fee mode on in/out side, and limit order mechanism. Affected endpoints are swap, swap_exact_out, swap_with_price_impact, swap2, swap_exact_out2 and swap_with_price_impact2.
• Due to new limit order logic (consuming more CU), max bins to swap in 1 instruction changes from 280 bins to 260 bins
• Endpoint swap and swap2 bitmap extension account will be mutable due to limit order logic require flipping of liquidity tracking bits.
• Event FeeParameterUpdate added new field base_fee_power_factor
• AccountsType enum variants introduces TransferHookReferral. Clients building swap2, swap_exact_out2 and swap_with_price_impact2 instructions must update their RemainingAccountsInfo slices to include AccountsType::TransferHookReferral when the swap has host_fee_in account. Additionally, any required transfer hook accounts for the referral mint must also be provided in the instruction.

pub enum ConcreteFunctionType {
  LimitOrder = 0,
  LiquidityMining = 1,
}

pub enum CollectFeeMode {
  InputOnly = 0,
  OnlyY = 1,
}

​

TypeScript SDK: @meteora-ag/dlmm 1.9.8

​

Added

• Added function placeLimitOrder to place a new limit order. Only applicable for pair with function type of LimitOrder.
• Added function cancelLimitOrder to cancel an existing limit order.
• Added function closeLimitOrderIfEmpty to close a limit order if it’s empty.
• Added function enablePositionPermissionlessClaimFee. This allow non position owner to invoke claim fee instruction for other’s position.
• Added function getLimitOrderByUserAndLbPair to get all limit orders of a user for a given pair.
• Added function getLimitOrder to get limit order data by limit order pubkey.
• Added function addLiquidityByWeight2 which support token 2022 add liquidity by weight.
• Added function quoteCreateLimitOrder which returns the cost for creating a Limit Order

​

Breaking Changes

• Added concreteFunctionType, collectFeeMode parameters in createCustomizablePermissionlessLbPair function. This allow user to create pair with function of LimitOrder or LiquidityMining and collect fee in InputToken, or TokenY (single sided fee).
• Added concreteFunctionType, collectFeeMode parameters in getPairPubkeyIfExists function. This allow user to query existing pair with addition filter of function type and collect fee mode.

​

Removed

• Position type (v1) removed, there’s no more v1 position on chain anymore.
• updateBinArray function removed since it’s not used anywhere.

​

Changes

• Update logic of swapQuote and swapQuoteExactOut to limit order and collect fee mode.
• swapExactOutQuoteAtBin function’s ‘amountIn` now include fee.

​

CLI: 0.6.3

​

Added

• Added place_limit_order command to place limit orders
• Added cancel_limit_order command to cancel existing limit orders
• Added close_limit_order_if_empty command to close empty limit order account
• Added get_limit_orders command to query limit orders for a user on a specific pair
• Added set_permissionless_operation_bits command to set operation bits on a position

​

Commons: 0.3.3

​

Added

• Added DynamicPosition in dynamic_position.rs to support parsing on position account
• Added LimitOrder in limit_order.rs to support parsing on limit order account

​

Changed
