ClaudeCodeLog · x · 2026-07-22
Claude Code 2.1.217 shipped a small but concrete CLI update.
- Removed the TESTENABLESESSIONPERSISTENCE env var from the CLI surface.
- Bundle size grew by +222.6 kB, with prompt files up 3 and prompt tokens up 7,002.
- Prompt token mix shifted slightly toward system tokens, while tool tokens fell.
- The release also clarifies the grep tool docs, recommending it for search tasks and refining parameter descriptions.
The quoted reply adds more context from the changelog: emoji shortcode autocomplete, transcript-write failure warnings, and safer handling when session saving is disabled via inherited environment variables.
