There is a setting if you'd like to continue to see it: showThinkingSummaries.
See the docs: https://code.claude.com/docs/en/settings#available-settings

Piece of free PR advice: this is fine in a nerd fight, but don't do this in comments that represent a company. Just repeat the relevant information.
> Thinking summaries will now appear in the transcript view (Ctrl+O).
