What To Do

​

Program: presale 0.1.1

​

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
