## [1.0.0] - 2026-07-16

### ⚠️ Breaking Changes

- **ata:** `Instruction::Transfer`, `Instruction::Burn`, `Instruction::Create` now requires a `token_program_id` field. Any existing call site that omits it will fail to compile. ([5229855](https://github.com/logos-blockchain/lez-programs/commit/5229855d57cc05623ca2f776f2b99b912d9ac195))
- **amm:** AddLiquidity, RemoveLiquidity, SwapExactInput, SwapExactOutput, and NewDefinition instruction variants now require a `deadline` field. ([6b21c36](https://github.com/logos-blockchain/lez-programs/commit/6b21c3695a5dd1ac321e5965293d7010df7e9c6e))
- Update dependencies and implement new required features across multiple modules ([471abef](https://github.com/logos-blockchain/lez-programs/commit/471abef7192b4a77f341eab8bc49c7c4c79e48fd))
- **amm:** `PoolDefinition` Borsh serialization format has changed. Existing on-chain pool accounts encoded with the `active` field are incompatible with this version. ([4a9a441](https://github.com/logos-blockchain/lez-programs/commit/4a9a441ccd19d038e6fe304f459d4b92410645e7))
- **amm:** The Swap instruction variant and swap() function are renamed to SwapExactInput and swap_exact_input(). Callers must update instruction construction and any IDL-generated bindings. ([4419e1e](https://github.com/logos-blockchain/lez-programs/commit/4419e1e9a004524728f5a31ba898363759de7439))
- **amm:** NewDefinition instruction requires an additional LP-lock holding account derived via `compute_lp_lock_holding_pda(amm_program_id, pool_id)`. ([fddd6e1](https://github.com/logos-blockchain/lez-programs/commit/fddd6e15bdd6a4ccc10b6993c3f4f1ae15cb7ae1))
