AddedmaxEffortLevel setting (top-level or per model under `modelSettings`): caps the effort level on every provider, including Bedrock, Vertex and Foundry; users can still pick a lower level
Added--system-prompt-snapshot off to render the system prompt fresh on every request instead of reusing the conversation's recorded prompt (for iterating on prompt text)
Claude TagAdded a "Use a custom connector" link to the preset connection forms in Claude Tag admin settings, so you can switch to a custom connection without starting over
~changed 2
Self-hosted runnerChanged--use-anthropic-git-proxy to be reported to the server at registration and to print a warning for each session that still clones through the legacy git proxy
GatewayChangedforward_user_identity upstreams to return a 429 as-is to a developer whose email was forwarded, instead of failing over to the next upstream, so the proxy's per-user limits hold
↑improved 7
Improved the /diff panel: it no longer flashes "0 files changed" and a spinner before settling, and its empty state is centered in the panel
Improved the Bash tool's description guidance so Claude describes what a command does in plain words instead of echoing the command
Improved sandbox guidance so Claude suggests `/copy` when clipboard commands such as `pbcopy` fail inside the sandbox
Improved--resume first-render time for sessions with many Bash tool calls
Improvedprompt input responsiveness: keystrokes no longer occasionally wait a frame behind spinner or streaming repaints
Improvedprompt-cache stability: subagents and sessions started with `--system-prompt` or `--append-system-prompt` now record the system prompt and tool definitions once instead of re-rendering them
ImprovedArtifact tool publish errors: when a publish is refused, the message now says why and what to do about it
✓fixed 41
Fixed Cowork scheduled tasks in the cloud failing at startup for organizations whose managed settings require sandboxing
Fixed/context and other local command output rendering blank on mobile clients
Fixed shift+enter and option+backspace not working after reconnecting to a tmux or ssh session inside an agent view
Fixed the dim last-prompt header not appearing at the top of the conversation when scrolling up in fullscreen mode
Fixed Workflow agent() calls with large output schemas being refused in auto mode instead of being checked by the safety classifier
Fixed a case where a marketplace entry path containing a backslash could bypass the containment check for fetched marketplaces on macOS and Linux
Fixed expired AWS or Google Cloud credentials under a host app such as Claude Desktop retrying ten times with a generic "request failed" before the re-authenticate error appeared
Fixed resuming a session after `/compact` or another slash command ran via `-p --resume`: a spurious "Continue from where you left off." turn is no longer inserted
Fixed resuming a large session (transcript over 5 MB): parallel tool calls and their hook output are no longer dropped from the reloaded conversation
Fixed managed allowedHttpHookUrls, `httpHookAllowedEnvVars` and `allowedChannelPlugins` to admit nothing, not everything, when unreadable
Fixed/login on machines whose managed settings require Claude apps gateway sign-in: Esc now closes the dialog instead of doing nothing
Fixed artifact publishes cut off by a dropped connection mid-upload: they now retry once when Claude Code can tell the upload never completed, instead of reporting an unknown outcome
Fixedeffort: frontmatter on custom commands, skills, and subagents being ignored on models whose default effort is still pinned (Opus 4.7, Opus 4.8, Fable 5)
Fixed artifact publish failing with an unhelpful error when the page file isn't valid UTF-8 or contains a replacement character (U+FFFD); the error now names the line and column to fix
Fixedclaude agents `@` directory menu not listing repositories created after the session started
FixedRemote Control clients that join a Claude Desktop or VS Code session showing a stale permission mode until it was changed again
Fixedclaude remote-control exiting and dropping every attached session when its server credential expires (about 30 days after start); the host now re-registers and keeps going
Fixed the usage-limit warning flickering on and off during a session when requests for different models or modes report different limit windows
Fixed earlier reasoning being dropped when an MCP server re-sends, or a built-in tool re-renders, a tool the model already loaded
Fixed a tool that disappears mid-conversation, from a disconnected MCP server or an upgrade, rewriting the tool list and discarding earlier thinking
Fixed a background worker forked from a conversation adding EnterWorktree to the conversation's tool block mid-session, which broke prompt-cache reuse
Fixed mid-session MCP and plugin tools being added to the tool list in sessions without ToolSearch, which broke prompt-cache reuse; supported models now receive them as deferred definitions
Fixed switching models with /model re-sending every tool definition (a prompt-cache miss); commit and PR attribution text now arrives as a conversation note that updates on model changes
Fixed resumed sessions rewriting the inline tool set when an MCP connector reconnects at a different moment than before
Fixed resumed sessions re-rendering tool descriptions instead of replaying the recorded ones when the first turn ran a tool
Fixed prompt-cache misses and dropped extended thinking when a claude.ai connector's tools change between a session and its resume
Fixed resumed sessions rewriting earlier MCP tool announcements (and dropping extended thinking) before their connectors reconnect
Fixed a prompt-cache break when a print-mode (`-p`) conversation is resumed interactively: the system prompt prefix no longer changes
VSCodeFixed the extension host hanging at 100% CPU when forking, editing an earlier message, or rewinding in a conversation whose saved transcript contains a cyclic parent link
VSCodeFixed pasting a screenshot on WSL2/WSLg inserting raw image bytes into the chat input; the image is now attached when the clipboard provides it, otherwise the paste is ignored
VSCodeFixed chat diff blocks always rendering with a dark editor theme; they now follow the active VS Code color theme, including high contrast
VSCodeFixed mixed right-to-left and English text rendering in the wrong order while typing in the message input
VSCodeFixed accepting an edit in the diff view on a file with Windows (CRLF) line endings failing with "String not found in file"
Claude Code on the webFixedgh and GitHub API calls failing in organizations without the Claude GitHub App; they now use your connected GitHub account and say so when none is connected
Claude TagFixed Claude replying "The API rejected the request as invalid" when the organization has run out of usage credits; the reply now says so and explains how to add more
Claude TagFixed thread requests to edit or delete a message Claude posted at the channel's top level being answered with a correction instead of reaching the session that posted it
Claude TagFixed **Connect** on Tool access requests under Admin settings > Review requests failing with "Authorization failed" or showing the requested access bundle as deleted
