Why QUIC Shipped a Version 2 With No New Features
Internet protocols were built to be upgradable. In 2017, a Chrome update tested that in Montgomery County, Maryland, where upwards of 30 percent of the district's roughly 50,000 school Chromebooks got stuck looping at the login screen, locking students out.
The cause was a web filter that didn't recognize the new greeting the browser sent when it connected. It had been built assuming nothing would change, and it wasn't alone. Engineers spent the following years working around boxes like it.

News in Context
In February 1994, Martijn Koster sold early web developers on robots.txt with one line: it "doesn't require any server/client/protocol changes." A site owner posted a text file naming pages that automated crawlers should skip. Nothing else had to change.
Kevin Kelley's October 30 Internet-Draft makes the same offer for AI training. Robots.txt groups its rules under crawler names. Kelley invents a name no crawler carries, __usage_ai-training, and puts ordinary Allow and Disallow lines under it. Older software sees instructions for some other crawler and skips them.
As in 1994, cost decides where the rule goes. A preference about what models may learn from now lives in a file built to say which pages may be downloaded. It counts only where software learns the new name. Google says it aims to start in 2027.

Mobile Money Still Runs Inside the Operator's Session
In Nigeria and Kenya, money moves through text menus on ordinary phones, using a 1990s design that was never meant to carry it. That design assumed the mobile network writing a menu also owned the call the menu ran over. Then banks started writing the menus, while the networks kept the calls. In October 2019, Nigeria's largest network announced a charge of ₦4 for every 20 seconds a customer spent in a bank's menu, metering money transfers the way it meters phone calls.
Screen Reader Users Never Took the Page at Its Word
On the web, code written for blind users is picking up visitors it was never built for. Hidden labels in a page tell blind users' software "this is a button," and those users learned the labels don't always deliver. The web standards body's guide calls such a label a role and warns developers, "A role is a promise," because tagging a plain box as a button doesn't make it work like one. Now AI agents that use websites on people's behalf are reading those same labels.
