Claude Code now keeps a record of which tasks own background shells that run quietly, and clears that record when its task tracking is reset. Tasks it registers are also now marked differently depending on whether they were set up to run quietly.\n\n**Why**\n\nThis points to changes in how Claude Code notifies you about background shells.\n\n- Area: Sessions\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
