 ## Features
 
-- First-class zsh history support, including extended history lines and zsh-metafied command decoding
+- First-class zsh history support, including extended history, multiline commands, and zsh-metafied command decoding
 - Dry-run by default
 - Reasoned removals for every dropped entry
 - Duplicate removal while keeping the latest occurrence
