The deprecation is in [reward-pool-internal #3](https://github.com/MeteoraAg/reward-pool-internal/pull/3), which is open. `@meteora-ag/farming-sdk@1.1.0` is the version in that pull request. npm still publishes [`@meteora-ag/farming-sdk@1.0.18`](https://www.npmjs.com/package/@meteora-ag/farming-sdk). > [!WARNING] > > **Breaking release.** `initialize_pool`, `create_user`, `deposit`, `fund`, `authorize_funder`, `deauthorize_funder`, `toggle_permission`, `unpause`, and `migrate_farming_rate` fail with `Deprecated` (6012). Stakers exit with `withdraw`, `claim`, and `close_user`. ## Release summary | Component | Version | PR | | - | - | - | | Program | `0.2.2` | [reward-pool-internal #3](https://github.com/MeteoraAg/reward-pool-internal/pull/3) | | TypeScript SDK | `1.1.0` | [reward-pool-internal #3](https://github.com/MeteoraAg/reward-pool-internal/pull/3) | The SDK package in this pull request is `@meteora-ag/farming-sdk`. ## What We Shipped * Deprecated new farms, new user accounts, new stakes, and reward funding * Left `withdraw`, `claim`, and `close_user` as the staker exit * Left `pause`, `withdraw_extra_token`, and `close_pool` for the pool authority after the reward period * Added `closeUser` to the TypeScript SDK ## What To Do

  • `initialize_pool`, `fund`, `authorize_funder`, `deauthorize_funder`, `toggle_permission`, `unpause`, and `migrate_farming_rate` fail with `Deprecated` (6012).
  • `pause` still runs after `reward_duration_end`. `unpause` fails, so a pause stays in place.
  • `close_pool` requires the pool to be paused, the reward period to have ended, `user_stake_count == 0`, and `staking_vault.amount == 0`.
  • Stop creating farms and stop funding rewards.
  • Leave funded rewards in place until `reward_duration_end`. Stakers claim through that time.
  • After the reward period, `pause` the pool, `withdraw_extra_token` for any stake tokens above `total_staked`, wait until every user account is closed, then `close_pool`.
  • Skip `migrate_farming_rate`. `get_reward_a_rate` and `get_reward_b_rate` read the u128 rate, and read the legacy u64 rate when the u128 rate is zero.
## Program: `farming` `0.2.2` Program ID (mainnet and devnet): `FarmuwXPWXvefWUeqFAa5w6rifLkq5X6E8bimYvrhCB1` [Program PR #3](https://github.com/MeteoraAg/reward-pool-internal/pull/3) ### Changed * Upgrade to Anchor 1.2.1. The program is built for SBPF v3. Single-reward pools still pass one token account for reward A and reward B. Those accounts are marked `dup` so Anchor 1.2 accepts the duplicate mutable account. * Funded pools keep distributing rewards until `reward_duration_end`. `fund` no longer extends that time. * `withdraw`, `claim`, `close_user`, `pause`, `withdraw_extra_token`, and `close_pool` keep working. `pause` still requires `reward_duration_end > 0` and a current time after `reward_duration_end`. * `close_user` still requires `balance_staked == 0`, `reward_a_per_token_pending == 0`, and `reward_b_per_token_pending == 0`. It decreases `user_stake_count` by 1 and returns the rent to the owner. * `close_pool` still requires `paused`, `reward_duration_end > 0`, a current time after `reward_duration_end`, `user_stake_count == 0`, and an empty staking vault. The authority signs. Remaining reward vault balances go to the refundee token accounts, and the vaults and pool account are closed. ### Deprecated * `initialize_pool`, `create_user`, `deposit`, `fund`, `authorize_funder`, `deauthorize_funder`, `toggle_permission`, `unpause`, and `migrate_farming_rate` always fail with `Deprecated` (6012). Their accounts and instruction data are unchanged. * `migrate_farming_rate` is unused. `Pool::get_reward_a_rate` and `Pool::get_reward_b_rate` return `reward_*_rate_u128`, or `_reward_*_rate` when the u128 rate is zero. > [!WARNING] > > Stop creating farms. Do not fund a farming pool, and do not stake LP into one. ## TypeScript SDK: `@meteora-ag/farming-sdk` `1.1.0` [SDK PR #3](https://github.com/MeteoraAg/reward-pool-internal/pull/3) > [!TIP] > > `@meteora-ag/farming-sdk@1.1.0` is the version in PR #3. It is not on npm yet. npm still publishes [`@meteora-ag/farming-sdk@1.0.18`](https://www.npmjs.com/package/@meteora-ag/farming-sdk). ### Added * `closeUser`. Closes the user account and returns its rent to the owner. The program allows it once nothing is staked and no reward is pending. * Re-exports the farming IDL and constants from the package entrypoint. ### Deprecated * `deposit`. The method still builds a transaction. The program rejects `deposit`, and `create_user` when the user account is missing, with `Deprecated` (6012). Exit with `withdraw`, `claim`, and `closeUser`. ### Changed * The exit is one transaction: `withdraw` the full balance when it is above zero, then `claim` when there is a reward or a stake was withdrawn, then `closeUser`. When the staking mint is also a reward mint, `withdraw` and `claim` can both create that token account. Keep one of those create instructions. * `getUserBalance` throws when the wallet has no user account in the farm.
