It names the contributions behind the release: [Wouter Lemaire](actor:lemaiwo) for the first Cloud Foundry deployment and the first multi-backend implementation, [Sami Bouguerra](actor:samibouge) for NetWeaver 7.50 fixtures and activations that looked successful but were not, [Clément Ringot](actor:clementringot) for BTP login and Cloud Connector fixes, and [Geert-Jan Klaps](actor:geert-janklaps) for S/4HANA Public Cloud support. It places SAP's own [ADT MCP Server](artifact:sap-adt-mcp-server) as the choice for a developer inside VS Code or Eclipse and ARC-1 as a shared service on BTP, and it stops short of a licence answer: the ADT web endpoints are not listed as published APIs in the SAP Business Accelerator Hub, so readers are told to ask SAP whether their agreement allows third-party tools to use them before a broader or production rollout.","short":"Release of ARC-1 1.0 with experimental multi-system mode","authors":["actor:marianfoo"],"published":"2026-08-03","offers":["concepts"],"part_of":"content:how-i-use-ai-for-development-and-why-context-matters","position":10,"provenance":{"discovered_via":[{"source":"source:zeis"}],"first_seen":"2026-09-15"},"drafted_with_ai":true,"published_on":"source:zeis"},"readings":{"liveness":[{"label":"Checked against the source","tier":"unknown","evidence":"nobody has checked it"},{"label":"Source reachable","tier":"unknown","evidence":"not crawled"},{"label":"Age","tier":"good","evidence":"published 2 months ago"}],"compatibility":[{"label":"Version","tier":"good","evidence":"arc-1 1.0.0"},{"label":"Moved since?","tier":"poor","evidence":"arc-1 1.1.0, 1.4.0 — 1 recorded break"},{"label":"Findings","tier":"good","evidence":"none flagged"}],"reach":[{"value":null,"unit":"views"},{"value":null,"unit":"comments"},{"value":null,"unit":"likes"}]},"signals":null,"series":{"container":false,"of":10,"at":10,"parts":[{"position":1,"title":"How I Use AI for Development and Why Context Matters","url":"https://blog.zeis.de/posts/2026-04-20-how-i-use-ai/","published":"2026-04-20","state":"indexed","id":"how-i-use-ai-for-development-and-why-context-matters"},{"position":2,"title":"ABAP and Agentic AI: The Hidden Problem in Real Projects","url":"https://blog.zeis.de/posts/2026-04-22-ai-abap-development/","published":"2026-04-22","state":"indexed","id":"abap-and-agentic-ai-the-hidden-problem-in-real-projects"},{"position":3,"title":"Introducing ARC-1: A Secure ADT MCP Server for Enterprise SAP Development","url":"https://blog.zeis.de/posts/2026-04-27-arc-1/","published":"2026-04-27","state":"indexed","id":"introducing-arc-1-a-secure-adt-mcp-server-for-enterprise-sap-development"},{"position":4,"title":"ARC-1 on SAP BTP: Secure ABAP Agentic Development Beyond the Laptop","url":"https://blog.zeis.de/posts/2026-04-29-arc-1-btp/","published":"2026-04-29","state":"indexed","id":"arc-1-on-sap-btp-secure-abap-agentic-development-beyond-the-laptop"},{"position":5,"title":"ARC-1 with Copilot Studio: SAP System Context Beyond Developers","url":"https://blog.zeis.de/posts/2026-05-05-arc-1-copilot-studio/","published":"2026-05-04","state":"indexed","id":"arc-1-with-copilot-studio-sap-system-context-beyond-developers"},{"position":6,"title":"ARC-1 with Joule Studio: Bringing Real ABAP System Context into Joule","url":"https://blog.zeis.de/posts/2026-05-08-arc-1-joule-studio-clean-core/","published":"2026-05-06","state":"indexed","id":"arc-1-with-joule-studio-bringing-real-abap-system-context-into-joule"},{"position":7,"title":"From SEGW and Legacy UI5 to RAP with ARC-1","url":"https://blog.zeis.de/posts/2026-05-11-segw-to-rap/","published":"2026-05-11","state":"indexed","id":"from-segw-and-legacy-ui5-to-rap-with-arc-1"},{"position":8,"title":"ABAP Development Automation with ARC-1 and GitHub Workflows","url":"https://blog.zeis.de/posts/2026-05-12-arc-1-abap-cicd-review/","published":"2026-05-12","state":"indexed","id":"abap-development-automation-with-arc-1-and-github-workflows"},{"position":9,"title":"Before You Upgrade S/4HANA: Static UI5 Checks with MCP","url":"https://blog.zeis.de/posts/2026-05-20-ui5-upgrade-mcp/","published":"2026-05-20","state":"indexed","id":"before-you-upgrade-s4hana-static-ui5-checks-with-mcp"},{"position":10,"title":"ARC-1 1.0: One Deployment, Multiple SAP Systems","url":"https://blog.zeis.de/posts/2026-08-03-arc-1-update/","published":"2026-08-03","state":"indexed","id":"arc-1-1-0-one-deployment-multiple-sap-systems"}]},"edges":{"authors":[{"ref":"actor:marianfoo","name":"Marian Zeis","json":"/actors/marianfoo.json"}]}}
