What has changed since

An entry is only as true as the day it was written.

Flags move on the server after a release ships. Anthropic's own notes land days later and their documentation later still. Sometimes an entry turns out to be wrong and gets corrected by hand. All of that is recorded against the entry it happened to, and this is the whole of it in the order it happened.

Nothing here replaces an entry. Every line links to the page its release published, still saying what that release said, because a correction is added and dated rather than swapped in.

v2.1.284tengu_lantern_wick_text Flag reading movedThe flag server now returns "Usage limit reached; a short grace allowance remains, then this turn is cut off without warning. Judge what's left: if it's genuinely only a few steps, finish it properly, then stop and say so without extra polishing. Otherwise don't attempt it all: finish the piece in hand and at most two more like it, then stop. The allowance also pays for any subagents you have running: they don't get this message and will keep going, so it's up to you how to handle them. Either way, end by telling the user their usage limit was reached, what's done and what's left." for tengu_lantern_wick_text, read as this account.

v2.1.281SessionStart Documentation arrivedA small documentation edit on Hooks reference touched a line naming SessionStart after this was published.
the line in the docs

Setup hooks have access to `CLAUDE_ENV_FILE`. Variables written to that file persist into subsequent Bash commands for the session, as in [SessionStart hooks](#persist-environment-variables). Only `type: "command"` hooks run on `Setup`. A …
v2.1.288/clear Documentation arrivedA small documentation edit on Manage costs effectively touched a line naming /clear after this was published.
the line in the docs

* **Clear between tasks**: Use `/clear` to start fresh when switching to unrelated work. Stale context wastes tokens on every subsequent message. Use `/rename` before clearing so you can find the session later, then `/resume` to return to …
v2.1.283HTTP_PROXY Documentation arrivedA small documentation edit on Securely deploying AI agents touched a line naming HTTP_PROXY after this was published.
the line in the docs

Note that not all programs respect `HTTP_PROXY`/`HTTPS_PROXY`. Most tools (curl, pip, npm, git) do, but some may bypass these variables and connect directly. For example, Node.js `fetch()` ignores these variables by default; in Node 24+ yo…

v2.1.287pluginConfigs Documentation arrivedAnthropic's documentation has since written up pluginConfigs, on How Claude remembers your project.
the line in the docs

You can also set the value in a settings file instead of `/config`. Add it to [`pluginConfigs`](/docs/en/settings-reference#pluginconfigs) under `cc-plugin-agents-md@builtin`, the ID of the built-in plugin that reads `AGENTS.md`. Claude Co…
