Quiet multi-beat day: Coldcard CVE, three AI releases
Bitcoin Optech flagged a severe COLDCARD vulnerability plus two Core Lightning denial-of-service bugs. The Bitcoin beat saw a Bisq hotfix for the BitcoinJ chainwork bug, Coldcard Firmware 6.6, and a Fedimint Web RPC stream fix. AI infrastructure shipped three updates: llama.cpp added a driver version check for Windows Intel GPUs to mitigate crashes, InvokeAI 6.14.0 added video generation via Wan 2.2, and Cline CLI 3.0.48 moved history rendering into the TUI. Privacy side saw Tuta Calendar 355.260730.0 and a Proton blog post on document management systems. Self-hosting saw rclone 1.75.0.
