Microsoft has announced Xbox Backward Compatibility for PC, a new preservation program that will let players run select classic Xbox games on Windows PCs and handhelds like the ROG Xbox Ally. Tom's Hardware reports: "This marks the beginning of a broader effort to preserve XBOX games from the past and bring them to PC over time," the company said in a blog post authored by Xbox "VP next generation" Jason Ronald. Alongside backward compatibility, the company says games will also include new features. The four titles in the announcement are: BLiNX: The Time Sweeper; Conker: Live and Reloaded; Crimson Skies: High Road to Revenge; and Fuzion Frenzy. You can now buy all of these games on PC, and they're also included in all Xbox Game Pass plans. Anyone who already owns these titles digitally on console can also now play them on PC or handheld, with support for Xbox Play Anywhere and Xbox Cloud Gaming. Crucially, this appears to be a digital-only preservation effort, so it won't help anyone who only owns physical copies of these games. Xbox has reportedly been testing a way to digitize physical games as far back as Xbox One, but that hasn't yet materialized yet. Alongside the preserved original gameplay, Xbox claims these games will let users customize graphics settings, with up to 4x resolution scaling, VSync support, Fullscreen and Windowed modes, anisotropic filtering, and enhanced anti-aliasing, with more features to come in the future. Notably, Xbox will add achievements to select original Xbox games on console and PC.

Longtime Slashdot reader williamyf writes: FireFox 153 was released today. The most important user-facing changes are improvements to PDF handling (you can now merge PDFs and add images to them), and HDR video playback (on Windows, provided HDR is active systemwide). Other under-the-hood changes include browser-wide containers and QWAC support. The full list is in the change notes. But the most important feature is that this version is an ESR and, therefore, defines the ESR feature set for the next year. Why is being an ESR so important, you ask? 1.) ESR, rather than "normal" (a.k.a. Rapid Release), Firefox is the out-of-the-box browser for many important distros, including Debian, RHEL, Kali, Tails, SUSE Linux Enterprise, Slackware, and others. 2.) Many organizations, large and small, standardize on Firefox ESR as their default browser, regardless of the default browser included with their OS. 3.) Firefox ESR is the basis for many downstream projects, such as Waterfox and KaiOS. All these projects will inherit, for a year, whatever ESR brings to the table today. 4.) Many ISVs and SaaS providers, if they certify their wares for Firefox at all, certify for the ESR version only. Please note that ESR 153 will not be offered as an automatic update until two months from now (ESR 140 will still be supported). If you want it now, you will need to download and install it manually. Also of note, ESR 115 will be supported until March 2027. If you use an unsupported version of macOS or Windows (like Windows 7 or 8.x), this is the version to get. However, even Mozilla cautions against running a supported browser on an unsupported OS: "Note that Microsoft ended official support for Windows 7, 8, and 8.1 in January 2023. Unsupported operating systems receive no security updates and have known vulnerabilities. Without official support from Microsoft, maintaining Firefox for outdated operating systems becomes costly for Mozilla and risky for users."

Today, the Linux Foundation launched the x402 Foundation to standardize internet-native payments for AI agents, APIs, and applications, based on Coinbase's contributed x402 protocol. Backed by companies including AWS, American Express, Cloudflare, Google, Mastercard, Stripe, and Visa, the effort aims to make payments work directly over HTTP (assuming users are comfortable letting AI agents handle financial transactions). "The whole idea is to give agents access to money and, through that financial independence, improve their set of capabilities to pretty much anything on the internet," Lincoln Murr, Coinbase's AI product lead, told CNBC last month when the company announced the protocol. "In the 2010s, every internet company dealt with the transition from desktop and web into a mobile environment. And now in the late 2020s, we're seeing the exact same thing happen where agents are going to be the new primary economic actors on the internet."
