## Version history (last 4 releases)

### 1.3.0 — 2026-05-20

**Live mid-race review** — scrub back through earlier finishes and place marks while the race is still recording. Recorder and reviewer iPads stay in sync.

**Multi-iPad backup recording** — pair two or more iPads on the same race for redundant camera angles. Switch between views during review; drag panes to rearrange.

**Bib-number marking** — assign athletes to marks by bib number with automatic name lookup, alongside or instead of lane assignment. Per-race mark mode (Lanes / Bibs / None) persists.

**Spectator timer screen** — open the iPad's `/timer` URL on any device on the local network to show a live race clock plus provisional results. Times now display naturally ("10.12" instead of "00:10.12") for sub-minute races.

**Laptop archive download + offline review** — pull a race archive to your laptop and review it in the browser without keeping the iPad nearby.

**Smoother video review** — triple-buffered primary video for flicker-free frame stepping across segments. Frame-accurate marks at 60, 120, or 200 fps. Configurable arrow-key scrub speed (default 1.5×).

**Reliability fixes** — single-source-of-truth race files for consistent state across review, export, and live mode. Robust chunk rollover for long live recordings. Lane-color bracelets in the assign UI. Backup audio capture of the starting sound. Larger LISTENING banner while waiting for the gun.

### 1.2.0 — 2026-03-30

Multi-Person Timing Workflow — One person operates the camera and timer on the iPad while others review video and mark finish times from any browser on the local network. The built-in review server streams race video, syncs marks in real-time, and supports multiple simultaneous reviewers. Password protection available for shared networks.

Bluetooth Keyboard Controls — Operate the timer hands-free with a connected keyboard. Return to start/pause/resume, S to stop, Escape to cancel, L for listen mode. Works through all screens including the race review overlay.

Remote Control — Start, stop, and manage races from a phone or laptop browser at /remote. Race picker remembers your position, create new races without touching the iPad, and keyboard shortcuts match the iPad controls.
