## What's New

The ZED SDK 1.2 release includes a major update of Unity and ROS plugins, along with new SVO recording modes.

## 1.2.0

### New Features

#### New recording modes

* A new lossy compression mode is introduced in this release. It improves the compression ratio by 5 with minimal loss in image quality and is faster than previous compression modes.

#### Frame drop detection

* Dropped frames can now be detected by calling `getFrameDroppedCount()`.

### SDK

#### Improved SVO recording

* Added lossy compression mode.
* Improved lossless compression and limited frame drops during recording.
* Added `recording_state` structure for `record()` function output. The structure contains status, current and average compression time/ratio.

#### Bug Fixes

* Fixed bug when destroying `Camera` object that could lead to a crash.
* Fixed bug (Jetson only) when calling `retrieveMeasure_cpu()` and `writePointCloudAs()` functions that stored a part of the image.
* Fixed bug when using `setCameraSettingsValue()` in SVO mode.

### Compatibility Notes

* Jetson TK1: This is the last update for Jetson TK1. Next releases will support TX1 only.
