  ## Program: `presale` `0.1.1`

  Program ID (mainnet and devnet): `presSVxnf9UU8jMxhgSMqaRwNiT36qeBdNeTRKjTdbj`

  [Program PR #33](https://github.com/MeteoraAg/presale/pull/33)

  ### Fixed

  * Calculation of `vesting_start_time`, `vesting_end_time`, `lock_start_time`, and `lock_end_time` now correctly handled
  * Added missing `params.validate()` call in `handle_initialize_fixed_price_presale_args`
  * Fixed issue where fixed price presale could not complete if `minimum_cap` and `maximum_cap` were configured to unreachable values
  * Fixed bug where presale registry could consume supply from another registry's presale

  ### Added

  * Added option to allow fixed price presale to disable withdraw
  * Added option to allow both fixed price and FCFS presales to prevent ending presale early when cap is reached
  * Added closure of `MerkleRoofConfig` account
  * Added support for the `security_txt!` macro

  ### Changed

  * Presale mode now reserves `presale_mode_raw_data: [u128; 3]`, used for storing mode-specific data (e.g. price in fixed mode)
  * Removed `lock_start_time` and `lock_end_time` fields as they can be represented by `presale_end_time` and `vesting_start_time` and were unused
  * For permissioned mode:

    * In dynamic price presale, `buyer_minimum_cap` must be 1 and `buyer_maximum_cap` must be `presale_maximum_cap`
    * In fixed price presale, `buyer_minimum_cap` must be the minimum possible quote token value and `buyer_maximum_cap` must be `presale_maximum_cap`
    * This change reduces errors when creating whitelist wallet caps that prevent escrow account creation

    ## TypeScript SDK: `@meteora-ag/presale-sdk` `0.0.6`

    [SDK PR #9](https://github.com/MeteoraAg/presale-sdk/pull/9)

    ### Added

    * `disableWithdraw` option on fixed price presale mode. Allow creator to disable withdrawing from the vault after deposit.
    * `disableEarlierPresaleEndOnceCapReached` option. Allow creator to prevent the presale end immediately once the target cap reached on FCFS and fixed price presale.
    * `immediateReleaseTimestamp`. Allow creator to configure the timing of immediate release portion of token.
    * `calculateLockAndVestDurationFromTimestamps` helper function to calculate lock and vest duration from presale end time, lock end time, and vest end time.
    * `getOnChainTimestamp` helper function to get current unix timestamp from on chain clock.
    * `getRegistryRemainingDepositQuota` function on `IPresaleWrapper` to return remaining deposit-able amount on specific registry.
    * `closeMerkleRootConfig` function to be able to close merkle root config account.

    ### Changed

    * `getPendingClaimableUiAmount` and `getPendingClaimableRawAmount` of `IEscrowWrapper` added `currentTimestamp` parameter. Can be retrieved from on chain clock using `getOnChainTimestamp` helper function.
