Free · official sources only
A dated log of what the official sources actually did — not what commentators said about it. Every entry links the page or the text it came from.
What we watch: EUR-Lex and the European Commission's Article 50 pages — the transparency guidelines, the Code of Practice on Transparency of AI-generated Content, and the Commission's AI Act FAQ. That list is the whole list. We do not watch "everything", we do not watch national authorities in 27 member states, and we do not watch the trade press.
What we do not promise: a schedule, or how fast anything appears here. One person maintains this. You get the entry when it is checked and written, and the date on it is the date it was checked.
As of 21 September 2026. Last checked: 21 September 2026 — no new events.

2 December 2026
The transitional period for machine-readable marking of AI systems placed on the market before 2 August 2026 runs out. It is a deadline for the providers of those AI tools, not for the businesses using them.
No change to your disclosures required.
2 August 2026
The AI Act’s transparency obligations become applicable: telling people they are interacting with AI, disclosing AI-generated or manipulated content that could pass for authentic, disclosing AI-written text published to inform the public, and machine-readable marking of synthetic output.

27 July 2026
The Digital Omnibus on AI moved the AI Act’s high-risk phase-in dates and created a transitional period, to 2 December 2026, for the machine-readable marking of systems already on the market before 2 August 2026. It did not postpone Article 50 itself.

"Guidelines on the implementation of the transparency obligations for certain AI systems under Article 50 of the AI Act" — the Commission’s own reading of who must disclose what, with definitions, exemptions and practical examples. Interpretive guidance; the binding text remains the Regulation.

10 June 2026
The closing plenary published the final Code. It is voluntary, and aimed mainly at providers of AI systems that generate content. The Commission and the AI Board have assessed it as an adequate voluntary tool for demonstrating compliance with the transparency obligations. That assessment does not make the Code binding, and it does not replace Article 50: adherence is voluntary, the Article 50 duties are not.

This page tracks the law: what official sources published, and when. The changelog tracks us: what we changed in the widget, the texts and the guides, and why. They are deliberately separate — an official event does not always need a product change, and a product change is never a legal event.
Want to know which of these duties are yours in the first place? The free 60-second check answers that, and the FAQ covers the rest.
