Changelog

User-visible additions, changes, and fixes for Alpha Compose.

0.8.0 - 2026-08-05

Replaced the homepage's all-or-nothing video list with responsive rich cards, public playlist metadata, accessible user-controlled rotation, and independent player and metadata fallbacks.

Opened Alpha Compose access to eligible people with a verified Google account, without requiring prior membership approval.
Added a signed-out homepage signup for important product updates without retaining the submitted address in application storage, logs, or analytics.
Explained that Alpha Compose is currently completely free, will always offer a free tier, and will add paid premium features later.
Added a responsive signed-out homepage carousel that follows the live Alpha Compose YouTube playlist and keeps playlist context when opening a selected video.
Added private video preview preparation for browser-incompatible source videos. The original Drive file is unchanged, each private preview expires after 24 hours, and every charged attempt uses the displayed processing allowance.

Prepared private videos now honor nonzero byte-range requests when seeking during playback.

Added a public, release-specific changelog and visible semantic version plus immutable build identity across the complete Alpha Compose web experience.

Local builds identify themselves as build dev; deployed builds identify the exact source commit using its first seven characters.

Added direct, resumable Google Drive source-video uploads, an accessible branching compose wizard, and a choice of 8-bit or 10-bit transparent ProRes overlays.

Added explicit Project JSON export and import, route-aware review, frame-accurate output selection, optional timer and SpO2 overlays, and owner-bound playback of completed H.264 videos.

Added private Google Drive source playback, shared-clock and matching-moment synchronization, recording-clock confirmation, keyboard and fullscreen timing controls, contextual help, and the public product FAQ.

Added the Alpha Compose finished-video workflow, authenticated Google Drive delivery, key-moment previews, early-access requests, member administration, personal API tokens, and operational logs.

Added bounded transparent ProRes rendering with generated heartbeat audio and support for Polar CSV, Garmin FIT, and OxiWear heart-rate and SpO2 activity data.
