Week 42, 2026
Coverage window 9 – 15 October 2026.
For the interpretation of this week, and why configuration written once for an agentic tool now needs a calendar, see the companion essay: Weekly AI Tools That Matter to Me: Part 12, Week 42. This page is the record; the essay is the read.
This week’s record
Claude Desktop removed the old names of several managed-configuration keys and documented that a profile still using them now behaves as if the setting were absent, which for extension signing means unsigned extensions load.
- Google made Gemini 4 Argon generally available in the Gemini app, the API and Gemini Enterprise, where it stays off by default until the toggle switches on from 27 October.
- Gemini Enterprise Workflow Builder can now connect to Salesforce, Microsoft Teams and Notion to search data and automate actions.
- Google began rolling out skills in the Gemini app and delayed skills in Workspace to launch them “in a safe and reliable manner”.
- Claude Desktop now completes an admin-enabled import from a third-party deployment, including local MCP servers and skills, without asking each user to confirm.
- Antigravity 2.23.0 added a permissions preset picker in the message box; OpenAI put Composer predictions in Codex into beta.
What changed this week
| Platform | What changed | Source |
|---|---|---|
| Anthropic Claude DesktopReleased (Oct 13)Admin / breaking | v2.37337.1: former managed-configuration key names removed (isDxtEnabled, isDxtSignatureRequired, isDxtDirectoryEnabled, enduserAttribution, trustBootstrapLocalExec, inferenceGatewayHeaders). A profile that still uses one now has an unrecognised key whose setting no longer applies; for the extension keys “unsigned extensions load”, which the vendor notes “differs from earlier notes for third-party deployments”. Also developerModeEnabled; provider, gateway and collector hosts no longer added to the egress list automatically; OAuth connectors ask to sign in again once | Changelog |
| Anthropic Claude DesktopReleased (Oct 15)Admin / agents | v2.42304.0: where device management turned on the import from a third-party deployment, Claude adds and starts local MCP servers, installs allowed extensions and plugins and uploads skills that grant tools or declare hooks “all without asking you to confirm” (not for organisations under the HIPAA restriction); app-run Git operations no longer run repository hooks; the persistent “Always allow” switch now also governs Code sessions | Changelog |
| Google AntigravityReleased (Oct 12)Agents / permissions | 2.23.0: permissions preset picker in the message box, with Use Global Settings to revert a project; .zip and folder attachments; Fix with Agent for MCP servers that fail to start; plugin command prompts show the plugin’s name; fix for a custom agent that ignored skills, rules, plugins and hooks listed with relative paths. 2.23.1 (Oct 13) fixes the license picker | Changelog |
| Google Gemini 4 ArgonGA (Oct 13)Model | Generally available in the Gemini app for Pro and Ultra subscribers, in the API with a 1,048,576-token limit and configurable thinking levels, and in Gemini Enterprise web, mobile and AI developer tools: “Turned off by default. The toggle defaults to on beginning October 27, 2026.” A Cyber Permissive variant is GA behind the Fairwind Program allowlist | Gemini Enterprise release notes · Agent Platform release notes · Gemini app updates |
| Google Gemini EnterpriseReleased (Oct 13 – 14)Agents / connectors | Workflow Builder connects to Microsoft Teams, Notion and Salesforce to search data and automate actions; Gemini 4 Argon in Workflow Builder (Oct 14, same default rule); Gemini 3.8 Flash GA in the UK with in-country data residency (Oct 14) | Release notes |
| Google WorkspaceRolling out / delayed (Oct 13)Rollout | Skills in the Gemini app rolling out from 13 October to mid-November, with no admin controls for app skills; skills in Workspace delayed until further notice for Rapid and Scheduled Release domains | Workspace Updates |
| Google Workspace StudioRolling out (Oct 9)Automation | Nested conditionals, Gmail triggers that skip replies, Meet outputs with full invitee lists and follow-up draft templates, and a Search for a Doc step; on by default | Workspace Updates |
| OpenAI CodexBeta (Oct 9)Product | Composer predictions: a suggested next message in Codex threads, accepted with Tab and never sent automatically; on by default for personal Pro users aged 18 and over in the Codex desktop app | ChatGPT release notes |
Late captures in this edition. Claude Desktop v2.31226.0 (8 October): the desktopHome key for Unified Claude (beta), which combines Chat and Cowork; without the key an organisation stays on the current split “until November 10, when Unified Claude goes on for all orgs”; scheduled tasks now stop and show the prompt for a tool marked “ask” instead of skipping it; a skill switched off in Customize is no longer offered (Changelog). Anthropic published a Usage Policy update on 8 October, effective 12 November, with a new section on deceptive campaigns and artificial activity, “whether political or commercial” (Anthropic), and launched the Anthropic Cyber Mission the same day. OpenAI added plugin access by role for Enterprise and Edu workspaces on 8 October (Enterprise and Edu release notes). Gemini Enterprise let administrators enable Claude Opus 5.5 and Sonnet 5.5 in AI developer tools on 8 October, off by default with consumption billing. Antigravity 2.22.0 (8 October) added plugin UI extensions in the side pane.

How this is compiled. Each edition is assembled from official release notes, changelogs and newsrooms. An AI assistant does the first-pass scan, reading release notes in a browser or through vendor-published Markdown routes, and I review and edit before publishing. Items are checked against the primary source; anything I could not confirm is marked inline. Dates and status reflect what was published as of the current-as-of date and can change.
Corrections and method notes. Spot an error? Tell me and I will fix it in the next edition. Several items dated 8 October, the closing day of the previous window, were published after that edition was compiled and are recorded here as late captures. Cross-note: Gemini Enterprise’s Salesforce connection and Anthropic’s commercial deceptive-campaign rules are also relevant to MarTech Watch, Week 42.
AI Watch is compiled and edited by Andrea Veggiani, Head of Cross-Channel Marketing & MarTech Solutions at BitBang.
