Lumen Code 0.1.2

What's new in 0.1.2

This version speaks Lumen Code protocol 1.0, now final and frozen. Nothing changed on the wire: 0.1.2 works with 0.1.0, 0.1.1 and the web pages in both directions.

• A transfer can no longer get stuck. If a received file fails its check (a damaged packet slipped through, or two transfers had the same ID), the receiver drops what it collected and starts again by itself. Before, it kept showing "checksum mismatch" forever.
• Glare on one corner no longer stops a transfer. The file's descriptor now moves around the frame instead of always sitting in the top-left corner.
• Safer receiving. Files larger than 256 MB are refused with a message, compressed data cannot expand beyond the announced size, and received file names are cleaned before they are shown or saved.
• Photosensitivity warning. The send screen says that the code flashes up to 60 times a second.

Specification: docs/PROTOCOL.md (中文).

The Windows build is not code-signed yet: SmartScreen asks once ("More info" > "Run anyway"). The webcam receiver is tested on macOS; the Windows (Media Foundation) and Linux (Video4Linux) camera paths are new and untested on real machines — reports welcome.

Phones: build the iOS and Android apps from src/ios and src/android, or use the web pages (send.html, recv.html) in any browser.

Checksums: SHA256SUMS (Windows, Linux) and SHA256SUMS-macos (macOS images, attached by hand after signing).
