Three things that changed on 2026-10-28

1DoorDash signed an agreement with Maplebear Inc.

What happened

On 2026-10-28, DoorDash signed an agreement with Maplebear Inc. Merger agreement to acquire Instacart; Instacart becomes DoorDash wholly owned subsidiary. 1 source on record.

Why it matters

Maplebear is Instacart's corporate name, so this is the biggest restaurant-delivery app agreeing to buy the biggest grocery-delivery app. If it closes, one company would set the fees, delivery-worker pay and store partnerships for a large share of the doorstep economy, which is why antitrust regulators will want a close look.

Takeaway

Watch for a regulatory review announcement and whether Instacart's fees or membership terms change in the months after closing - because fewer rivals usually shows up in the price.

2Google released Gemini 4 Carbon

What happened

On 2026-10-28, Google released Gemini 4 Carbon. 1 source on record.

Why it matters

Google has added a new model to the Gemini 4 family, but the one source on record doesn't say what Carbon is for, what it costs, or how it compares with Google's other models. Until that's published, treat it as a product-line update rather than a proven step forward.

Takeaway

Check Google's model page for Carbon's price, speed and intended use before switching anything to it - a new name isn't a new capability until the numbers say so.

3GitHub changed a policy: Copilot included with Enterprise

What happened

On 2026-10-28, GitHub changed a policy: Copilot included with Enterprise. 1 source on record.

Why it matters

Copilot, GitHub's coding assistant, now comes with the Enterprise plan instead of being something companies decide to buy on top, so far more workers at those companies will likely have it by default. That makes AI-written code an ordinary part of company software, and it raises questions about review and security, not just whether to adopt it.

Takeaway

Ask your employer, if it uses GitHub Enterprise, whether Copilot is now switched on and what the rules are for reviewing its suggestions - because included by default means used by default.
