-## Known issues
+## 15.04.2020 2.0.0
 
-We are working to deliver durable fixes for this non-exhaustive list of known issues:
+## Added
+
+- Face detector changed to Blazeface
+- Standalone support checker component
+- Assets have been moved to cdn.iproov.app for better load speed
 
-- Occasionally flashing may crash if started quickly. This appears to affect all devices.
-- The scan display in some devices may appear warped or squashed.
+## Fixed
+
+- Timing regularity restored
+- We now wait for WASM modules to fully load before interacting with them (stops crashing)
+- SVG repositioning has been tweaked to remove jank
+- Video feeds that change resolution, particularly on iMacs, no longer cause face alignment issues
+- Bundle size has been reduced as part of an ongoing initiative to reduce page load weight
+- King Kong has been tamed 🍌
+
+## Changed
+
+- `@iproov/html5` is now the iProov Web SDK, and so has been renamed to `@iproov/web`
+- Class names are now used to identify language text elements rather than blanket tags
+- The rotate animation has been switched from lottie to gif (saves bundle size)
+- Support is now checked by the support checker component rather than a whitelist of browsers and devices
+- Alignment feedback frequency has been tweaked to work better with a new face detector in a future release
+- Face detection lifecycle has been tidied to facilitate a new face detector in a future release
+- PicoJS's face detector memory allocation and maxFaces have been reduced for performance on lower end/swapping devices
+- Various telemetry improvements around face detection: accuracy, reduction in performance cost, etc
+
+## Removed
+
+- Option `screen_brightness` removed; due to lossless encoding and improved adaptive screen brightness, it is no longer needed. Removing it saves around 300kB from the bundle.
+
+## Deprecated
+
+- The screen_brightness animations and usage in older clients have been deprecated and will be removed in a later release.
+- Loading assets from the iproov.app domain have been deprecated in favour of using the CDN.
