Multi-beat day: 4 AI, 3 Bitcoin, 4 Privacy
No dominant theme today. AI shipped infrastructure plumbing: llama.cpp added flash-attention tuning for Metal, ElevenLabs Swift SDK brought client-error parsing and audio-thread optimization, NanoClaw posted a breaking Slack integration overhaul. Privacy tools posted four releases, most incremental: Tuta and Tuta Calendar hit matching Android and iOS builds with unspecified fixes, Notesnook Android logged a point release, Mullvad announced Multihop mode changes without a version tag. Bitcoin delivered BTCPay Server 2.4.3, a security release recommended for multi-user deployments, BitBox02 Firmware 9.27.0 with full-amount display and message-signing for m/45' keys, and Stack Wallet 2.7.1 with ShopInBit and Firo Spark fixes.
