Arc browser announces shutdown: a million weekly active users still couldn't buy it a future.
According to news from Bijie, the company behind the Arc browser has announced that it will completely shut down the macOS and Windows versions of Arc on December 22, 2026, and has already closed new user registration. Starting November 23, mobile AI features, login, and tab syncing will also be phased out. Going forward, the team will fully shift its focus to the AI browser Dia. Arc was launched in 2022, initially available only to Mac users via invitation, fully opened up in 2023, and gradually expanded to Windows and mobile platforms in 2024. Although Arc had more than 1 million weekly active users, it failed to achieve widespread adoption. Founder Josh Miller admitted in 2025 that Arc was too complex for ordinary users and had too high a learning curve. The team decided to stop maintenance on the grounds that browser security in the AI era requires sustained investment, and engineering and security resources must be concentrated on Dia.

Vercel takes aim at long-lived API keys: flagged as "insecure" by year-end, phased out entirely next year.
CoinWorld news: Vercel has announced that it will phase out long-lived static keys in its marketplace. Starting November 30, third-party services that still rely on long-lived keys and do not support Vercel OIDC authentication will be marked as "insecure," and by January 2027, non-compliant services will be removed. Long-lived keys are like keys that never automatically expire; once leaked, attackers can use them for a long time. The OIDC authentication promoted by Vercel allows programs to obtain short-lived credentials based on their own identity, limiting the scope of access and permissions. After the credentials expire, the SDK can automatically reacquire them and reduce extra requests through caching. Vercel itself has also suffered security incidents. In April, the third-party AI tool Context.ai was compromised, and attackers used it to breach Vercel's internal systems and read some customers' environment variables. Vercel's investigation found that only 8.4% of SaaS providers support more secure authentication methods.
