 ## Unreleased
 
-### Changed
-
-- Release artifacts now introduce themselves properly as `sesamo-vMAJOR.MINOR.PATCH.zip`, with a matching checksum. Mystery meat belongs in freezers, not Downloads folders.
-- Replaced the austere keyhole mark with a hand-painted kawaii sesame wizard casting an illuminated `↑ ↓ B A` spell at a storybook gate. The old door has been reassigned to infrastructure.
-
 ### Planned
 
 - WordPress integration, accessibility, RTL, and mobile-admin verification.
 - Official Plugin Check and WordPress.org readme validation.
