PJ Hyett announced an extension of a sale until Sunday due to the positive response from new signups, addressing initial confusion regarding the upgrade path from free to paid accounts. The sale was initially designed to benefit only new users, but it has now been adjusted to include existing free account holders, allowing them to upgrade to a paid plan without needing to enter credit card information. Hyett also assured users who had previously upgraded and received a receipt before the code update that they could disregard it.
