Claude Code 2.1.323 removed subagentStatusLine, and a contributor says the removal needed a grace period

The v2.1.323 release notes, published November 12, list "Removed the subagentStatusLine setting". Subagent rows now use the default look, and settings files that still hold the key load without error. The issue's author reports that 2.1.322 ran the configured command and 2.1.323 never calls it, with no startup warning. By the users' account, the custom rows showed each running subagent's context use, token and dollar spend, model, reasoning effort and prompt-cache state. They also say mods cannot redraw those rows, because no mod render site covers the agent panel, and that a request for one filed October 29 has had no answer. The thread had 22 thumbs-up when we read it.

A contributor who said he made the change replied that plugins shipping a settings file made little sense with only two supported keys, and that he should have given a grace period. He said a grace period for the key will go in the next release, that the replacement is planned for mods, which have not landed yet, and he gave no ship date. One commenter's stopgap is to pin 2.1.322 with auto-update off, which gives up every later fix. The statusline documentation page no longer mentions the setting when we read it, although the issue says it did.

Why it matters: If you built per-agent cost or context displays on this setting, 2.1.323 broke them, and what is on offer is a temporary grace period, not a restoration. Until that release ships, the choices in the thread are pinning 2.1.322 or going without the rows. We did not check whether the grace period has shipped.
