AddedserverToolUses to the result of a mod's `turn.step` hook: the tool calls the API ran itself (the advisor), each with its id, name, input, start and end
AddedagentId to the `tool.check` event of plugin hooks, so a hook can tell a subagent's permission check from the main session's
Addedceiling to the question and verdict a mod's `tool.check` hook reads, naming the approval an organization requires for a tool
AddedThemeKey and `Color` types to the plugin hooks typings, so an editor lists the theme colors a mod's drawing can name
Added to claude plugin validate: each hook a mod registers at a gating site is listed with whether it has a `.catch` (`gatingHooks` under `--json`)
Added a Deny button to the Claude apps gateway's sign-in approval page: it ends the pending sign-in, so the waiting terminal stops within seconds
Addedclaude attach <name> and `claude logs <name>`: part of a session name works in place of the id
Added/claude-api managed-agents-onboard <url> to set up the Managed Agents pattern a page describes as `ant apply` files
Added/claude-api managed-agents-onboard <quickstart-name> to build a Console quickstart template, such as `deep-researcher`, with the `ant` CLI
Added a warning when a managed settings file is a link to a file outside the managed settings folder
Added a /status and doctor warning when managed settings ignore user-configured sandbox allowRead paths or allowed domains
VSCodeAdded a screen reader announcement, "Message queued.", when you send a message while Claude is working
VSCodeAdded a way to review and run a plugin marketplace's install or update command from the Manage plugins dialog
Claude TagAdded fast mode in Slack: mention Claude with `!fast` to switch a thread to fast mode, moving it to Opus if needed, and `!fast off` to switch back; replies show (fast) while it's on
Claude TagAdded the optional Path prefixes field when creating a custom connection in an access bundle, so its allow rule can cover only those paths instead of the whole host
~changed 25
ChangedCLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC to also skip the startup connection warm-up
Changed Claude in Chrome so that a project's settings files can no longer turn it on; use `--chrome`, `/chrome` or your user settings
Changed the Bash tool to ask for permission before running `pyright`, which is no longer treated as a read-only command
Changed what a mod's $.process.spawn rejects with when another mod denies it after the child ran: it now says the call ran and a plugin withheld its result
Changed the background daemon's log to write a multi-line message as one JSON-quoted line
Changed skills and custom commands to refuse a `!` shell command that contains raw control characters other than tab and newline, with a message that shows where they are
Changed/artifacts: opening an artifact in your browser now closes the list
Changed Bash permission checks so that more forms of the `ps` command ask for approval instead of running without asking
Changed plugin hooks so long text is clipped and logged instead of being refused or dropped silently
Changed background sessions whose scheduled task is gone: they now move to Completed about 20 seconds later and can be updated or shut down when idle
Changed the "Press ← again" confirm on a just-cleared prompt: a second ← no longer has to wait a second before it switches, and holding ← down now switches too
Changed the errors shown when the /ultrareview upload fails at a git step: they name the step and what to try, and no longer repeat git's own error text
Changed/code-review at medium effort to also report cleanup and CLAUDE.md conventions findings on models without tuned review settings, including Opus 5.5 and Sonnet 5.5
Changed an in-process teammate's agent_id in Agent results to its agent ID (its `name@team` address stays in `teammate_id`); TeammateIdle hooks no longer fire from its subagents or forks
Changed background sessions waiting on a scheduled wakeup (`/loop`): they are now left running through updates and low memory, where being restarted or shut down could silently lose the wakeup
Changed/model, `/effort` and `/rename` sent from `claude agents` to a busy background session to apply right away, without a confirmation, instead of when the turn ends
Changed the Claude apps gateway's minimum supported PostgreSQL version from 14 to 11
Changed the interactive session's WebSearch budget to refill over time (100 calls/hour; `CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR` sets the rate, 0 turns it off) instead of ending after 200 calls
ChangedCLAUDE_CODE_DISABLE_ATTACHMENTS so a repository's `.claude/settings.json` or `.claude/settings.local.json` can no longer set it; shell, user and managed settings still can
Changedclaude plugin update on a plugin loaded from a directory to print just its reason, without the "Failed to update plugin" prefix, as for built-in plugins
Changed the built-in gh api in cloud sessions: a host other than github.com set in `GH_HOST` or `GH_REPO` is now refused (use `--hostname` or a full URL), and stderr notes requests to other hosts
Changed the claude-api skill's Managed Agents examples to turn off the web tools unless the agent needs them and to use the `auto` permission policy
Self-hosted runnersChangedclaude --environment <id> to create its session through the current Sessions API; printed and JSON session ids keep their session_… form
VSCodeChanged message timestamps to show by default (turn them off with the Claude Code: Show Message Timestamps setting)
Claude TagChanged the channel instructions limit to 8,192 characters instead of bytes, so non-English text gets the same room, and added a character count beside Save on the Configure page
↑improved 19
Improved MCP startup behind a network proxy: a server the proxy blocks (HTTP 403) is no longer retried three times
Improved permission prompts from background agents to show the Ctrl+X Ctrl+K shortcut that stops all background agents
Improved the built-in plugin-authoring skill: Claude now gives the one command another person runs to install a mod you made, and writes it in a README's install section
Improved the reply to /plugin in the desktop app's Code tab: it now says where to install and manage plugins there
Improved the Bash changed-files view: when a chained command includes git merge, pull or checkout, it lists the files without full diffs
Improved the Claude apps gateway's log when an upstream's cloud credentials or connection fail: the warning now ends with the underlying cause
Improved the error shown when a cloud session is started without a claude.ai sign-in: it now names `claude auth login` and /login and no longer blames API-key authentication
Improved the Read tool's message for binary files: it now points Claude to a skill or a shell command that can read the format
Improved the error shown when a git config file stops the `/ultrareview` upload: it is about half as long and says what kind of file is the problem
Improved the errors shown when the /ultrareview upload refuses a checkout: each known cause now has its own message, with a way to fix it
Improved the Claude apps gateway to log a warning during the last 30 days before the certificate it presents to the identity provider expires
ImprovedClaude in Chrome: a `browser_batch` call now gets 90 seconds, up from 60, before it is reported as timed out
Improved the Claude apps gateway's browser sign-in pages: brand fonts, centered layout, and dark mode
Improved responsiveness while resuming large sessions: timers, input and rendering keep running while the transcript loads
Improved the / and @ suggestion lists: the selected row now starts with a ❯ pointer, so you can see it without color
VSCodeImprovedContinue After Reload: tabs reopened after VS Code restarts its extensions now also finish a step the restart interrupted
VSCodeImproved file pills in messages: hovering one now shows the file's path from the project folder, so same-named files can be told apart
Claude TagImproved Claude's notice in your direct messages when your own Claude plan's usage limit is reached: it shows within seconds and says when the limit resets
Claude TagImproved the earlier Claude in Slack app's reply when it can't start a session: it now says what failed and who can fix it, in full only once per thread
