## [Unreleased](https://github.com/hyperion-project/hyperion.ng/compare/2.0.12...HEAD)

### Breaking

### Added

- Allow to build a "light" version of Hyperion, i.e. no grabbers, or services like flat-/proto buffers, boblight, CEC
- Allow to restart Hyperion via Systray
- LED-Device: Support retry attempts enabling devices, e.g. to open devices after network or a device itself got available (#1302)
 (Fixes that devices got "stuck", if initial open failed e.g. for WLED, Hue)
- LED-Devices: New UDP-DDP (Distributed Display Protocol) device to overcome the 490 LEDs limitation of UDP-RAW
- LED Matrix Layout - Support vertical cabling direction (#1420)
- Support additional Yeelight models
- LED-Devices: Show warning, if get properties failed (Network devices: indication that network device is not reachable)
- hyperion-remote: Show image filename in UI for images sent
- mDNS support for all platforms inkl. Windows (#740)
- LED-Devices mDNS discovery support and ease of configuration (Cololight, Nanoleaf, Philips-Hue, WLED, Yeelight); removes the need to configure IP-Address, as address is resolved automatically.
- Forwarder: mDNS discovery support and ease of configuration of other Hyperion instances 
- Grabber: mDNS discovery for standalone grabbers

## [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).
