Compiled by the Toolstash team · Updated

  1. Anthropic · Claude API

    The Messages API can now compact a conversation on demand on the Claude API, in beta with the…

    Send the top-level compaction parameter, and the API returns a signed compaction block that summarizes the messages you sent. On later requests, send that block first, in place of those messages. You choose when to compact, the request can run in the background, and you can keep recent turns word for word after the summary. On models with preserved thinking, the thinking in those kept turns can stay valid. With the thinking-binding-controls-2026-08-01 beta header, the input_transformations response field gains a second entry type, thinking_mismatch_allowed.

Switch to one of the recommended models, and update saved configurations, custom agents, and scripts that select gpt-5.3-codex-spark. For faster responses with a supported model, see Fast mode.

    Plugin MCP namespacing, conversation memory leak fixes, oversized file guardrails, and unsandboxed rule…

    Enhances startup migration diagnostics for unsandboxed permission rules, speeds up /resume with stale caches, automatically namespaces plugin MCP servers to avoid collision, resolves step-cache goroutine leaks, and fixes critical issues with Gemini API thinking block retention, oversized binary file loading, artifact reviews, and database cleanup.

    Quick chats with Pets and Appshots on Windows

    Keep ChatGPT close while you work in other apps. In the ChatGPT desktop app on macOS and Windows, you can now type a quick chat from the floating Pets controls and press Enter to send it. Use @ to add context and $ to choose a skill. Select the bell icon to follow progress in your threads, then select a thread to open the full conversation. Choose a companion or show just the controls in Settings > Pets. Press Option+Space on macOS or Windows+Alt+P on Windows to show the controls and focus Quick Chat. Pressing the shortcut again keeps Quick Chat open. You can change Show pet in Settings > Keyboard shortcuts. To hide the controls, select Hide pet in the command menu or Settings > Pets. On macOS, you can also send an appshot to the floating controls. Keep the main ChatGPT window in the background and choose Automatic for Appshot destination. Learn more about Pets. Appshots are now available in the ChatGPT desktop app on Windows. Press both Alt keys to share the frontmost app window with ChatGPT, then ask a question or describe what you want to do. An appshot includes a screenshot and available text from that window. You can customize the shortcut and choose which chat receives it in settings. Other improvements and bug fixes. Open files directly from a conversation's Sources panel, or download files that ChatGPT can't preview. Assign a Codex Micro key to Insert text and add your own reusable text to the active prompt without sending it. Reset a pet to its default size in settings. Custom pets also stay in place when you refresh their artwork. Keep unfinished comments on response text when you switch chats and return. ChatGPT dictation now respects your saved Main language preference. Keep tab widths and scroll positions more stable as you close browser tabs in full and split views.

    Claude Code 2.1.268

    11 new59 fixes26 other

    Added to the Claude apps gateway: with pricing: set in gateway.yaml, signed-in Claude Code clients receive the same rates through managed settings, so /cost and telemetry match the spend meter. Added a startup warning for gateways when access_control.allow_cidrs is empty, and a one-time warning the first time a request arrives from a public address.

  11. Anthropic · Claude API

    Claude Managed Agents permission policies now include auto: the server evaluates each agent or MCP tool call…

    Smart reports (beta)

    We’ve launched smart reports, which analyze how a team uses Claude and report on the work getting done, what it costs, where sessions run into friction, and which repeated patterns are worth packaging as shared skills. Smart reports are available in beta on Claude Enterprise plans. Learn more in Get started with smart reports.

  18. Anthropic · Claude Code

    Claude Code 2.1.267

    3 new41 fixes9 other

    Added maxEffortLevel 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).

  19. Anthropic · Claude API

    For cache diagnostics, the API now stores a request’s fingerprint only when the request includes the…

    A request that sends only the cache-diagnosis-2026-04-07 beta header is still accepted, but no fingerprint is stored. A later turn that points previous_message_id at it reports previous_message_not_found. Include diagnostics on every turn, with "previous_message_id": null on the first.

  20. OpenAI · Codex CLI

    Codex CLI 0.154.0

    6 new6 fixes2 other

    GPT-6-Astra is now available in the model picker and Amazon Bedrock catalogs. Experimental worktree support lets you create isolated checkouts for new or forked sessions using --worktree or /worktree, then browse and resume them.

    Model API retry resilience, headless print optimizations, and detailed tool approval prompts

    Improves resilience to transient model API errors with extended exponential backoff, accelerates startup and sign-in by reading cached credentials, streamlines headless execution and error reporting, enhances tool approval prompts with contextual action descriptions and reasons, and fixes issues across plugin reinstalls, plugin MCP working directories, subagent lifecycle states, and command memory leaks.

    Introducing new Documents section and several UX enhancements for organization and control

    External files such as Google Drive links, PDFs, and Office documents now have their own Documents section in the sidebar. This release also adds a virtualized viewer for large code and data artifacts, an option to hide whitespace-only changes in diffs, and clearer warnings when a configuration file fails to parse.

  23. Anthropic · Claude Code

    Claude Code 2.1.266

    1 fix

    Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented CLAUDE_CODE_USE_GATEWAY environment variable, previously ignored unless ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, apiKeyHelper, or custom auth headers failed every request with "Not signed in to the Cloud gateway". The variable on its own is ignored again; no configuration change is needed.

  24. Google · Gemini CLI

    Gemini CLI 0.59.0

    2 fixes2 other

    prevent SSRF in MCP OAuth metadata discovery and authentication. enforce fail-closed workspace trust and filter mcpServers in restricted mode.

    Added user.email and user.groups to the telemetry Claude Desktop and Cowork send through a Claude apps gateway, matching terminal sessions. Added support for pointing --plugin-dir at a folder of plugins: each child folder with a manifest loads, and children added or removed while running are picked up.

  26. OpenAI · Codex app

    Codex app

    Added a configurable shortcut to open web links in your default browser. Added Open with > New tab to file diffs so you can open a source file at the selected line in the app. Performance improvements and bug fixes.

    Codex MCP server removed

    The codex mcp-server command and standalone codex-mcp-server binary have been removed after their deprecation on August 24, 2026.
