What's changed

Added CLAUDE_CODE_RETRY_WATCHDOG_MAX_USAGE_LIMIT_WAIT_MS so unattended retry mode (CLAUDE_CODE_RETRY_WATCHDOG) ends a request at a usage limit that resets too far away instead of waiting Added OpenTelemetry tracing guidance to the claude-api skill, including setting up trace destinations with the ant CLI Added the % motion to vim mode: jump to the matching bracket, alone or with d/c/y Added rows to a mod's Input: a text field of several lines in the terminal, where Enter submits and Shift+Enter or a backslash before Enter starts a new line Added classifier_verdict and permission_mode to OpenTelemetry tool_decision events, so auto mode classifier decisions can be told apart from permission rules Added classifier_category to OpenTelemetry tool_decision events, naming the built-in rule a classifier block matched, when OTEL_LOG_TOOL_DETAILS=1 Fixed quitting removing a worktree made by a WorktreeCreate hook without asking when it may hold unpushed commits Fixed the fable (and best) model alias erroring on the Anthropic API when the newest Fable model is not available to your organization: Claude Code now retries once on the previous Fable model Fixed a misleading "Please run /login" error when a full disk keeps the login from being refreshed; the error now names the disk and says to delete files Fixed Grep and Glob reporting no matches when the search program failed unexpectedly before returning any results; they now return an error saying the search failed Fixed workflow agents sometimes skipping their step, and the run still reporting success, after reading the harness note that their task text carries no user authority Fixed artifact updates being refused where a PreToolUse hook covers Edit or Write; Claude now edits the file and then republishes instead of changing it in the publish call Fixed skills and commands with very many or very long argument names stalling for seconds when invoked; only the first 64 names, each up to 64 characters, are now filled in Fixed skills, commands and hooks using very large amounts of memory when their arguments fill many placeholders Fixed stray characters such as >0q covering the folder trust prompt, and >4m before the shell prompt at exit, in terminals built on VTE older than 0.53 such as MATE Terminal on RHEL 8 Fixed stray GOK text appearing in the prompt at startup in some versions of iTerm2 Fixed switching to a model whose name contains application-inference-profile running your awsAuthRefresh command and delaying model-switch hooks when the provider is not Bedrock Fixed sign-in refresh timeouts and unexpected sign-outs after a short command such as claude auth status or claude plugin list exited in the middle of a token refresh Fixed a tool call cut off by a message sent mid-turn during its permission check being reported to the model as rejected by the user Fixed a case where switching to a model with a smaller context window could spend usage credits on a summary by the previous model without asking first Fixed conversations being compacted over and over, on a model you didn't pick, behind an LLM gateway whose responses name a different model than the one requested Fixed vim mode sometimes staying in INSERT after Escape on a slow or busy machine Fixed Esc discarding a typed AskUserQuestion answer in vim mode: the free-text field now supports vim NORMAL mode, and Esc cancels only from NORMAL Fixed the Read tool reading binary files such as .xlsm, .parquet, .epub and .heic as text Fixed a Markdown table with only a header row drawing nothing when too wide for the terminal, including in plans on the plan approval card Fixed the /claude-api skill saying CMEK external-key endpoints aren't available on Claude Platform on AWS Fixed skills no longer being listed to the model after using /rewind Fixed the compaction row in a resumed session offering ctrl+o for history that is not loaded; it now says where the earlier messages are saved, and also shows in fullscreen Fixed the "new task? /clear to save tokens" hint coming back right after you interrupt a response Fixed the permission prompt for a plugin or skill hook's ask decision not showing which plugin or skill the hook comes from Fixed /diff not noticing a conflicted cherry-pick or revert in reftable repositories when one of its git checks timed out or failed Fixed workflow scripts asking for permission or being refused when read, edited or re-run after a Bash cd in the same session Fixed dim text on the dark ANSI theme and 16-color terminals: faint inside filled boxes, not faint under selection and search highlights, and list descriptions dimmed like other secondary text Fixed a mod's $.model.fork returning nothing-to-fork when called before the first response of a new Claude Code process had finished, as in claude -p runs and cloud sessions Fullscreen mode: Fixed /compact and auto-compact briefly freezing the UI while the visible transcript is rebuilt Self-hosted runner: Fixed sessions started from Slack being unable to find or attach a repository when managed settings restrict MCP servers; use deniedMcpServers to keep those tools off Self-hosted runner: Fixed sessions being reported as having a deleted source branch, and not retried, when an unrelated setup or session failure quoted git's missing-ref wording Self-hosted runner: Fixed the log promising a retry of a failed or declined session release for a session that is ending; repeated failures now show a count Windows: Fixed stopped background PowerShell commands missing the closing [killed] line in their output file Improved switching to a model with a smaller context window: a conversation too long for the new model is now summarized by the previous model first Improved rendering performance while a long-running subagent works: its progress trail now updates incrementally instead of being reprocessed in full on every render Improved artifacts: pages Claude writes now paint the band above a sticky header, so scrolled text no longer shows there in the mobile apps Improved mods: in VS Code and the desktop and mobile apps, a tree drawn above the question dialog can now hold Markdown and up to 48 rows; the terminal keeps 12 plain rows Changed a mod hook's .catch handler to run only when the hook throws or times out; events raised beneath the hook's own calls now skip that hook without asking its .catch Changed a mod's $.env.set to resolve with {} once the variable is set or unset, or with { deny } saying why when the write is not made [VSCode] Added LaTeX math rendering in Claude's responses, including $$ and multi-line \[ … \] blocks and inline $…$ and \(…\) math [VSCode] Added a "Get more usage" link to the usage-limit banner for Pro and Max plans in the VS Code and JetBrains panels [VSCode] Fixed a conversation that crashes or freezes the panel being reopened on every reload [VSCode] Fixed the chat panel slowing down during long thinking: it no longer re-parses the whole thinking text on every update [VSCode] Fixed diagnostics showing "[object Object]" instead of the rule code (e.g. MD013) for some language servers [VSCode] Fixed the native dictation audio module being loaded, to check microphone permission, where dictation is not offered (non-claude.ai sign-ins, remote windows)
