What's changed
Added a visible warning when memory usage is critical, with steps to free memory or restart safely
Added CLAUDE_CODE_MCP_STARTUP_WAIT_MS to bound how long the first non-interactive turn waits for connecting MCP servers ( 0 = don't wait)
Added effort attribute to the claude_code.llm_request OpenTelemetry trace span, matching the api_request event
Added claude_code.managed_settings_resolved OTel event: managed-settings sources and policy helper state; redacted settings and digests with OTEL_LOG_MANAGED_SETTINGS=1
Added store.connect_timeout_seconds to the Claude apps gateway config to lengthen the Postgres connect timeout (default 5 seconds), and improved the boot error when the database is unreachable to point to store.postgres_url and the configured timeout
Added enduser.sub , the IdP subject, to the telemetry Claude Desktop and Cowork send through a Claude apps gateway
Added a Claude apps gateway warning when a replica has more requests open than the 256 it sends upstream at once, and a startup log line showing that limit
Added click-to-expand for collapsed teammate and agent messages in fullscreen mode
Fixed sessions getting stuck endlessly retrying "unexpected tool_use_id" 400 errors: corrupted transcripts now self-heal where possible, and otherwise a clear error (with a /rewind hint) ends the loop
Fixed MCP servers configured as http that only speak legacy HTTP+SSE failing to connect when they answer the first request with 422 or another 4xx error
Fixed Streamable HTTP MCP tool calls timing out after about 5 minutes even when a longer per-server timeout was set
Fixed MCP prompts and resources not refreshing when a server sends list-changed notifications without declaring listChanged
Fixed MCP tool calls refused with 403 insufficient_scope being reported as an expired sign-in: the error now names the missing permissions and points to /mcp re-authentication
Fixed hook-driven sessions (such as an active /goal ) ending with "Prompt is too long" instead of compacting when the context overflowed again after a reactive compaction
Fixed an active /goal being lost when resuming ( --continue / --resume ) a session that had compacted
Fixed claude agents losing --model , --effort , --permission-mode , --allow-dangerously-skip-permissions and --agent after an auto-update relaunch
Fixed a per-turn slowdown when a language server publishes project-wide diagnostics for thousands of files
Fixed subagents with model: "opus" on Bedrock, Vertex or Foundry leaving the session's model when its id has no recognizable model family (unless ANTHROPIC_DEFAULT_OPUS_MODEL is set)
Fixed self-hosted runner sessions failing every turn with a 401 after a few failed token refreshes, until the next scheduled refresh; the runner now keeps retrying, and fetches a new token after a 401
Fixed clickable links to local file paths doing nothing in VS Code and other terminals that require a file:// URI
Fixed the transcript renumbering ordered lists in your own messages (typing "3. 2. 1." displayed "3. 4. 5."); numbers and "N)" markers now show as typed
Fixed AskUserQuestion preview notes being attached to a previously chosen option instead of the highlighted one
Fixed AskUserQuestion preview mode dropping the highlighted option when submitting a note with Enter
Fixed a resumed background agent keeping half of an interrupted tool batch when one of its calls was approved with a message
Fixed a local claude -p --resume started with CLAUDE_CODE_RESUME_INTERRUPTED_TURN not reporting background tasks the previous process left unfinished
Fixed the first turn of a cloud session sometimes starting without the tools of an SDK-hosted MCP server that was still connecting
Fixed background agent notifications claiming the agent had no live background work when it was still waiting on its own background task and would resume
Fixed error hints in Claude Desktop sessions to suggest slash commands like /usage-credits instead of CLI flags that cannot be used there
Fixed /schedule saving a routine's prompt without its message role when Claude writes the routine in the shape that listing routines returns
Fixed /status not showing the apiKeyHelper failure that its own error banner told you to check
Fixed /fast on in non-interactive sessions reporting on and then turning off under an organization's managed fast mode policy; it now says the organization has disabled it
Fixed the Artifact tool asking you to approve an update to an artifact that it then refused because the session had not read the latest version
Fixed Cowork and claude.ai cloud sessions with network access on treating reads of a teammate's artifact as if network access were off
Fixed a plugin or marketplace directory with no git repository of its own taking its version from an enclosing git repository, such as a git-managed ~/.claude
Fixed --strict-mcp-config with an empty --mcp-config holding the first non-interactive turn for up to MCP_TIMEOUT on incidental MCP servers
Fixed Stop prompt hooks re-sending their whole prompt on every block in a conversation; repeat blocks now name the condition with a 500-character label
Fixed extra empty editor windows opening at startup on Linux under Wayland when running inside the Cursor or VS Code terminal
Fixed an unhandled promise rejection in the Claude apps gateway when Postgres drops a connection during a spend check
Fixed Claude apps gateway cutting every open stream on SIGTERM: it now lets in-flight requests finish for up to 25 seconds before exiting ( CLAUDE_GATEWAY_DRAIN_TIMEOUT_MS )
Fixed installed_plugins.json being rewritten on nearly every start-up when plugin policy comes from remote managed settings, which made Claude Desktop reload every open session's plugins
Fixed headless and SDK sessions making a separate model call for every background task that finished; completions already queued are now answered by one call
Fixed the Bash tool re-sourcing the shell profile (a multi-second stall on the next command) after every plugin reload; it now does so only when the plugins' bin/ directories changed
Fixed plugins with a top-level $schema in hooks/hooks.json showing an "unknown key" notice
Fixed MCP connection errors and the MCP login tool's description showing secrets resolved from ${VAR} placeholders in MCP configs
Fixed Bash permission checks for commands that loop over or assign certain special shell variables; these commands now ask for permission
Fixed worktree-isolated sessions accepting Bash commands with certain nested shell expansions; these are now refused
Fixed the Edit permission prompt preview sometimes showing a different location than the approved edit in files with multi-byte characters
Fixed background commands being stopped after 30 idle minutes on machines under mild memory pressure; they're now stopped only when memory is critically low, and the debug log says why
Fixed a message a subagent sends to the main session disappearing from the Claude Desktop transcript after a relaunch
Fixed a plugin loaded from a .zip being served from a stale extraction after several overlapping reloads
Fixed a sub-agent's progress summary being replaced by a runaway multi-paragraph reply
Improved startup in --input-format stream-json sessions: the first turn no longer waits up to 2s for still-connecting MCP servers whose tools tool search defers; they arrive on a later turn
Improved Monitor tool notifications: a script's final output and its exit now arrive as one notification instead of two, saving a model turn
Improved Artifact tool errors: when you are not signed in to claude.ai the terminal now says so on the first attempt, and Claude is told to stop retrying a rejected call sooner
Improved artifact publishing: a publish built on an older version is stopped before it is sent, with the newer page to merge
Improved safety checks before removing an agent worktree that contains submodule checkouts
Improved OTEL_LOG_RAW_API_BODIES=file: output: a new index.jsonl and request_body_id / message.id event attributes link each response to its request file and transcript message
Improved Claude apps gateway boot: it now tries the first Postgres connection up to three times before exiting, so a database that is reachable a few seconds late no longer fails the boot
Improved the Claude apps gateway's spend-limit check under load: it now takes one database round trip instead of four, so fewer checks time out on a busy gateway
Improved Claude apps gateway sign-in rate limit errors: /login now explains the refusal, and the gateway log says which limit was hit and which setting to change
Changed Bedrock, Vertex, Foundry and telemetry-disabled installs to use the v2 MCP client and MCP 2026-07-28 negotiation with direct HTTP servers by default, as other installs already do (opt out: MCP_SDK_GENERATION=v1 or MCP_PROTOCOL_NEGOTIATION=legacy )
Changed /code-review to use leaner inline review prompts for every model that has no tuned settings of its own, instead of spawning many review subagents
Changed "type": "sdk" MCP entries in .mcp.json , settings, plugins and agent files to be skipped with a warning: only an SDK host application can register in-process servers
Changed artifact watching in local sessions: a new version published elsewhere no longer starts a turn; Claude learns of it from a later Artifact tool result
Changed plugin and marketplace clones to leave Git LFS files as pointers instead of downloading them; git lfs pull in the checkout fetches them
Changed self-hosted runners to skip a read-only repository the git host refuses at the access check instead of failing the session start
Changed the /status GitHub line to read "Cloud sessions", and /web-setup , /ultrareview , and teleport messages to say "cloud session" instead of "Claude Code on the web"
[VSCode] Added continuation of the step a window reload interrupted, labeled in the chat, with a Claude Code: Continue After Reload setting to turn it off
[VSCode] Added Memory and Instructions entries to the Customize menu: Memory shows the auto-memory toggles, the saved memories and the memory folders, and Instructions edits the CLAUDE.md files
[VSCode] Added a claudeCode.lockEditorGroups setting to stop Claude from locking the editor groups it opens in
[VSCode] Fixed a /btw side question asked in a new conversation's first seconds occasionally showing another session's side-question history

[VSCode] Fixed the Manage Plugins enable toggle and MCP servers dialog rows being unreachable from the keyboard
[VSCode] Fixed sign-ins and sign-outs made in a terminal not showing until a reload after CLAUDE_CONFIG_DIR changed in the Environment Variables setting
[VSCode] Fixed Edit diffs in the chat being cut off at the bottom at some panel widths and for long wrapped lines; diff boxes now fit the rows shown
[VSCode] Fixed overlapping settings writes from the extension leaving ~/.claude/settings.json unparseable or dropping a setting
[VSCode] Fixed Open in New Tab (Ctrl/Cmd+Shift+Esc) sometimes leaving the new tab's message box unfocused, so typing went nowhere until you clicked it
[VSCode] Fixed reopening a closed Claude tab splitting the editor layout when its locked group still holds another Claude tab and a file
[VSCode] Fixed New session opening another locked editor group whenever a file tab shared the group with your Claude tab
[VSCode] Fixed session names shifting sideways in the session picker while typing a search query
[VSCode] Fixed the plan review card cutting off its Send feedback button and reason field when a plan has several comments; the comment list now scrolls

[VSCode] Improved screen reader navigation of the conversation: each message is announced as "You" or "Claude", with the tool name for tool steps
[VSCode] Changed the default global gitignore file to $XDG_CONFIG_HOME/git/ignore when XDG_CONFIG_HOME is an absolute path
[Claude Code on the web] Added a "Compare against" branch picker to a cloud session's diff view, so you can diff its changes against any branch instead of only the base branch
[Claude Code on the web] Fixed git operations in cloud sessions failing with "service unavailable" when GitHub's token renewal briefly errors
[Claude Code on the web] Fixed editing a routine occasionally making it fire twice or re-enabling a routine that had just been paused
[Claude Code on the web] Fixed commits in cloud sessions occasionally failing with a signing error for a few minutes after the session's credentials refreshed
[Claude Code on the web] Fixed the toast after saving a routine whose GitHub trigger couldn't be linked to show the reason, such as a per-repository trigger limit, instead of only "edit to retry"
[Claude Code on the web] Fixed sessions sometimes flipping back to unread right after you mark them read
[Claude Code on the web] Changed routines to skip a run and retry for up to 72 hours when the owner's GitHub connection is missing, instead of switching the routine off at the first failed check
[Claude Code on the web] Changed a routine's on-hold notice: when your subscription is paused it now tells you to turn the routine back on yourself instead of promising an automatic resume
[Claude Tag] Added a Guests setting to the Add channel and Add workspace forms in Claude Tag admin settings, so owners can pick Inherit, Allow, Channel only or Restrict up front
[Claude Tag] Fixed Claude not answering when another Slack app or bot @mentions it; the tag now gets a reply and wakes Claude in a channel it had stopped following after days of inactivity
[Claude Tag] Fixed Claude missing another app's message that tagged @claude right after a new Slack channel was created; it's now delivered once Claude has joined
[Claude Tag] Fixed Claude folding a follow-up sent minutes after its last Slack message into it as a silent edit; late updates such as blockers now post as a new reply that notifies
[Claude Tag] Fixed Claude's Slack search failing with an error whenever it searched within a single channel; it now returns that channel's matching messages
[Claude Tag] Fixed a safety-filter stop silently resetting a Slack thread's context when nobody was waiting; Claude now always says so and no longer cancels background work still running

[Claude Tag] Improved Claude's live progress checklist in Slack: capped at 2,000 characters, reposted at most every 15 minutes in busy threads, with older "Latest task list" links updated
[Claude Tag] Removed the repeated guest-attribution note Claude appended to a Slack canvas each time it edited one in a channel using the "Channel only" guest setting
[Code Review] Fixed re-reviews occasionally leaving a fixed finding's thread open when the new review also filed a lower-severity note under it
[Code Review] Fixed rare reviews ending with "Code review encountered an error" when GitHub or an internal service failed transiently at launch; they now wait and retry
[Code Review] Improved how Code Review words each posted finding: short plain sentences that say who is affected, where the code goes wrong, and the fix up front
[Code Review] Improved the check-run card and PR comment when a review is skipped because of an organization limit: each cause now links the admin page that fixes it
