Welcome back to The Code Brew! ☕ Security Alert: Troy Hunt just added 630 million passwords to HIBP, courtesy of the FBI. In other big news, Dan Abramov launched the RSC Explorer, and Gemini 3 Flash is now on Vercel. For .NET devs, we have deep dives into C# 14, the new .slnx format, and a roadmap for the Critter Stack.
