- Fix NoSuchMethodError on Android 2.x: Dalvik before 4.0 can't link Object methods (toString/equals/...) called through an interface. Patch the bundled Bouncy Castle (tools/patch_bc_dalvik.py) and our own CertVerifier, and make build.sh fail if tools/scan_dalvik.py finds any such call - Treat a manually entered private address (10.x, 172.16-31.x, 192.168.x, .local) as home, so LAN servers that allow access without sign-in work - Send Plex client headers on media requests (files and transcodes) - Explain a 503 on a file as the server being unable to open it (drive or folder not available) - Connection log: home/away, token presence, Plex's file check and a direct file request in the streaming test Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
