Unclear The finding does not say how the second normalized form differs from the first.
What
When Claude Code looks up a session (a saved conversation) by its title, it compares what you typed against the titles in a normalized form, meaning a cleaned-up version of the text. It now also tries a second normalized form of what you typed, and a match on that form counts as exact.
Why
More of the ways you might type a session's name now count as an exact match for that session.
