## Removed

## [2.0.15](https://github.com/hyperion-project/hyperion.ng/releases/tag/2.0.15) - 2023-02

### Added

- Audio Grabber to add audio visualization support for both Windows and Linux.

To allow segment streaming, enable "Realtime - Use main segment only" in WLED's Sync Interfaces setup screen
- Allow to keep WLED powered on after streaming and restoring state
- Allow to Disable / Enable all instances (#970) by 
	- Suspend/Resume support for Linux and Windows (#1493,#1282, #978).
	Suspend/Resume/Restart is supported via API, UI, Systray and hyperion-remote
	- Idle scenario via Screen Locking (Linux/Windows), Screensaver invokation (Linux), hyperion-remote or API
	In Idle, all instances, components will be disabled besides the output processing (LED-Devices, smoothing).
	The current priorities will be cleared and the background effect per instance will be executed, if enabled.
	- Commands toogleSuspend and toggleIdle allow to flip between modes, e.g. might be used to trigger modes by a remote
- Reduced pixel processing to reduce resources on big assignment areas
- Support for squared mean color processing
- Support for dominant color processing on assigned LED areas (#1382). A simple and advanced way is provided. Advanced and high accuracy might be combined with reduced pixel processing to lower CPU usage.

### Changed

- REST API - Increased default timeout to address "Operation cancelled" errors
- LED Devices: Allow to differentiate between recoverable/unrecoverable errors
- Renamed LED area assignment naming to provide clarity on the processing algorithms

### Fixed

## [2.0.0-alpha.11](https://github.com/hyperion-project/hyperion.ng/releases/tag/2.0.0-alpha.11) - 2021-10-06

The release is primarily fixing issues introduced with alpha 10, but covering other findings too.
Thanks to everybody highlighting real problem areas, as well as to those proactively providing fixes for integration via pull requests.
Besides bug fixing, you will find some smaller enhancements which make everybody’s life easier.

The fact that WS281x devices must run under root caused many headaches before in getting them running.
We did not weaken security, but provide you with an easy to use script to switch the user-id of hyperion going forward. Furthermore, device configuration is blocked, if the environment does not allow it.

### Added:
- Script to change the user Hyperion is executed with.
To run Hyperion with root privileges (e.g. for WS281x) execute <br> `sudo updateHyperionUser -u root`
- Gif effects can source Gifs via URLs in addition to local files as input

- System info screen: Added used config path and "is run under root/admin"
- LED-Device enhancements
  - WS281x: Ensure that a device cannot be configured via the UI when Hyperion is not run with root privileges
  - Nanoleaf: Support discovering additional Nanoleaf devices, e.g. Shapes
  - Nanoleaf: Ability to restore state when Hyperion stops streaming<br>
    Note: In case previous state was a dynamic/temporary effect, the state cannot be restored
  - Nanoleaf: New Feature: allow to overwrite brightness by Hyperion

### Changed:

- The Systemd/Upstart/System-V-Init service registers Hyperion under the name hyperion instead of hyperiond, as this has caused confusion among users in the past.
- WLED and UDP-Raw: Limit maximum LEDs number to 490
- WS281x: Update DMA default as per rpi_ws281x recommendation
- Smoothing is paused when no input source is available (to save resources)
- Disable LED update streaming, if LED updates are not required, Sync. Video-Streaming between Layout and Simulation
- Load configuration of last instance used when loading the UI page, Streamline API requests to avoid unnecessary invocations (#1311)
- BobLight: Priorities are not limited any longer. BobLight can feed Priorities [2-253], default is still 128 (#1269)
- Amlogic grabber: Limit grabber to 30fps during discovery
- Amlogic grabber: Continuous image feed even when paused (to not have LEDs switched off), plus no delay when pausing/unpausing

### Fixed:

- Fixed that Smoothing with "Continuous Updates" disabled does not provides LED updates (#1068, #1240)
- Fixed Issue Blinking / flickering cursor with QT screen capture on Windows (#1328)
- Fixed Colour effect priority is not deleted when Colorpicker is open (double click on delete is required)
- Fixed reuse local SSDP address (#1324)
- Exclude FB Grabber on Amlogic platform, as FB is included in Amlogic Grabber
- Escape XSS payload to avoid execution (#1292)
- Include libqt5sql5-sqlite packaging dependency
- Fixed embedded Python location (#1109)

- LED-Devices
  - Fixed Philips Hue wizard (#1276)
  - Fixed AtmoOrb wizard
  - Fixed that Lightpack device does not core when lack of permissions error (LIBUSB_ERROR_ACCESS)
  - Fixed Atmo/Karate LED count constraint handling
  - Fixed Hue, Disable LED general options (HW Led count & RGB Byte order) as calculated
  - Fixed SPI, Tpm2.Net - Memory issues
  - Fixed: Nanoleaf does not turn on
  - Fixed LED layout - Additional parameters for classic layout were not saved (#1314)
  - Fixed Network LED-Device UI: Trigger getProperties for the configured host, when no hosts were discovered

### Removed:

- Smoothing: Removed "Continuous Updates" flag as it is obsolete.
In case an LED-device requires continuous updates, use the LED-Device's "Rewrite Time" parameter.

## [2.0.0-alpha.10](https://github.com/hyperion-project/hyperion.ng/releases/tag/2.0.0-alpha.10) - 2021-07-17

The focus of this release is on user experience.
We tried as much as possible supporting you in getting valid setup done, as well as providing enough room for expert users to tweak configurations here and there.
The reworked dashboard provides you now with the ability to control individual components, jump to key configuration items, as well as to switch between LED instances easily.
The refined color coding in the user-interfaces, helps you to quickly identify instance specific and global configuration items.

Of course, the release brings new features (e.g. USB Capture on Windows), as well as minor enhancements and a good number of fixes.

Note:

- **IMPORTANT:** Due to the rework of the grabbers, both screen- and video grabbers are disabled after the upgrade to the new version.
Please, re-enable the grabber of choice via the UI, validate the configuration and save the setup. The grabber should the restart.

- Hyperion packages can now be installed under Ubuntu (x64) and Debian (amd64/armhf) (incl. Raspberry Pi OS) via our own APT server.
Details about the installation can be found in the [installation.md](https://github.com/hyperion-project/hyperion.ng/blob/master/Installation.md) and at [apt.hyperion-project.org](apt.hyperion-project.org).

## [2.0.0-alpha.6](https://github.com/hyperion-project/hyperion.ng/releases/tag/2.0.0-alpha.6) - 2020-05-27
### Breaking
The release package names have been adjusted.\
If you used a `.deb` package please uninstall it before you upgrade
- Check for the package name `apt-cache search hyperion`. You may see now a entry like `hyperion-x86`, `hyperion-rpi`
- Remove with the correct name `sudo apt-get remove hyperion-XX`
