Dune Firmware Zone

Dune HD Pro 4K (revision tv292b)

This version is a minor update which only fixes regressions appeared in
the previous version 200331_2121_r13.

- Reverted the changes in auto framerate logic (which were introduced in
  the previous firmware version) for preferring video modes with higher
  framerate (such as 50Hz video modes for 25Hz content), because these
  changes cause problems when using TV's motion smoothing function, and
  because of some other problems with optimal handling of specific сases.

- Bugfix: Playback of audio files could unexpectedly stop in some cases.

This version is a small update which adds Dune-HD.TV application (for
Russia only) and a few other improvements and fixes.

- New feature: Added Dune-HD.TV application (available in "Dune HD
  applications" menu), which provides access to Dune-HD.TV TV and VOD
  service (available in Russia only).

- Improvement: Various minor improvements in autoframerate logic to better
  handle 4K video modes, to prefer video modes with higher framerate (when
  possible) for more smooth UI (for example 50Hz video modes for 25Hz
  content), and to better support some specific cases.

- Improvement: Realtek models: Improved support for playback of specific
  HTTP/TS streams, including better buffering handling and buffering
  progress indication and better compatibility with specific streams.

- Improvement: Realtek models: Added bitrate detection for HTTP/TS streams,
  improved bitrate detection for HLS streams.

- Improvement: Realtek models: Improved support for video codec detection.

- Improvement: "Skins" section of "Dune Store" (which was missing on all
  Android models) is now accessible via "Setup / Applications / Skins"
  menu.

- New SDK features (for plugin developers):
  - Added a new "dune_param" parameter "frame_rate" (value example: 50000)
    which allows the plugin to specify the framerate of the media stream to
    be used by the autoframerate mechanism when the framerate detection
    built into the player does not work good for some reasons (currently
    needed and supported only on Amlogic models).
  - Improved handling of the case when a plugin shows a GUI dialog on
    "install" or "update" plugin actions.
  - Added files with the information about the firmware version which was
    installed on first boot or after settings reset:
    /config/factory_boot_firmware_features.txt,
    /config/factory_boot_fw_info.txt

- Updated/improved UI translations for some languages.

- Minor other fixes and improvements.

This version is a small update which includes a few improvements and fixes.

- Bugfix: Photos with vertical orientiation were incorrectly shown in photo
  viewer.

- Bugfix: If an auto-updatable built-in plugin was hidden by deleting it in
  "Setup / Misc / Plugins", it was being restored and shown again after
  reboot.

- Bugfix: YouTube and Music apps: YouTube content could not be played in
  some cases.

- Bugfix: SmartBox 4K model: Online Subtitles feature did not work.

- "Dune HD" menu, which was added in the previous firmware update and which
  provides various information related to Dune HD (such as news, videos,
  user manuals and various other information about Dune HD media player
  models) is updated to the latest improved version. Improvements: 
  - New items are marked as read immediately when focused (w/o the need to
    open the item).
  - Minor bug fixes and internal improvements.

- Minor other fixes and improvements.

This version is a small update which includes a few improvements and fixes.

- Added automatic use of SmartYouTube Android app instead of the default
  YouTube Android app. This feature is enabled when the new setting "Setup
  / Applications / Android Applications/ Use SmartYouTube as YouTube" is
  set to "Yes". It is set to "Yes" by default on Amlogic models (in order
  to fix the problem with the default YouTube Android app is often not
  working on Amlogic models), and is to "No" by default on Realtek models.

- YouTube support in YouTube PHP plugin and Movies and Music applications
  updated to include some fixes.

- Bugfix: The menu "TV" could not work properly in some cases.

- Bugfix: "DISCRETE POWER OFF" IR code (used in some smart home
  integrations) could be handled wrongly in some cases.

- Bugfix: Realtek models: Fixed the problem that switching the player off
  using Bluetooth remote did not work in some cases.

  Bugfix: Realtek models: Resuming playback of some video files was very
  slow in some cases after playing these files with enabled subtitles.

- Bugfix: Realtek models: Playback error message could be shown in some
  cases when stopping the playback too quickly after time seeking.

- Bugfix: Models with Hi-Fi audio output (Ultra 4K and Max 4K): Fixed
  several bugs in the handling of Hi-Fi audio output and XMOS, which could
  lead to audio not not playing in certain cases (for example after playing
  video in Blu-ray menu mode, or after using Android applications).

- Bugfix: Models with Hi-Fi audio output (Ultra 4K and Max 4K): when
  playing SACD ISO (DSD) files, they could be wrongly played via the
  regular player rather than via Hi-Fi player.

- Bugfix: Pro 4K model (revisions tv292a and tv292b): Fixed the problem
  that USB 3.0 port could work with USB 2.0 performance.

- Bugfix: Neo 4K, Neo 4K T2, Neo 4K T2 Plus, Sky 4K Plus models (revisions
  tv173b, tv174a, tv174b, tv274a): Fixed the problem that storage devices
  formatted into ExFAT filesystem did not work in some cases.

- Minor improvements in the text messages and icon of "Setup / Misc /
  Support" menu.

- Removed some unsupported / non-working items from the setup menu.

- Updated/improved UI translations for some languages.

- Minor other fixes and improvements.

This version includes various new features, improvements and fixes.
In particular, this version includes new "Online Subtitles" feature
(possibility to download subtitles from Internet directly during file
playback).
NOTE: There were a lot of internal changes, so this version probably
includes some bugs (will be fixed in further versions).

This version is a small update with a few bugfixes for the version
190601_0246_r13.

- Bugfix: Realtek models: BD3D playback could work with problems.

- Bugfix: Realtek models: Time seek did not work when playing HLS video
  streams.

- Bugfix: Realtek models: Video parameters detection could work wrongly
  when playing multiple HLS video streams one after another.

  cases.

- Bugfix: Realtek models: Choosing player via POP UP MENU did not work in
  some cases.

- Bugfix: Realtek models: HLS video streams with multiple bitrates were
  played incorrectly in some cases.

- Bugfix: Music application updated to fix not working video playback.

- Bugfix: Kartina.TV application updated to fix some problems.

- Improvement: Realtek models: Optimized playback start time for HTTPS
  video streams.

- Minor other fixes and improvements.

- Realtek models: Updated to newer versions of core components of Realtek
  SDK. This makes it possible to implement various fixes and improvements
  for media playback functionality, but also could cause some regressions
  and new bugs (to be fixed in future firmware updates).

- Realtek models: Maximum supported number of audio tracks per one video
  file is increased to 256.

- Realtek models: Maximum supported number of subtitle tracks per one video
  file is increased to 256. (Up to 256 embedeed subtitle tracks, and up to
  64 external subtitle tracks.)

- Realtek models: Fixed problem that some AVI files were playing with
  stuttering when using internal player. Internal player is now again used
  by default for AVI files (instead of SPMC).

- Realtek models: DSD audio playback (ISO, DSF, DFF) is now supported not
  only via "Internal player (Hi-Fi)" playback engine, but also via
  "Internal player" playback engine, and is now supported on all Realtek
  models (not only on Max 4K and Ultra 4K, as before). This new way for DSD
  audio playback is optimized and is recommended for audio output to the
  standard digital audio outputs (HDMI output and standard S/PDIF output).
  Known limitations: only stereo DSD is supported; audio file should not be
  too long (maximum supported duration is approximately 67 minutes).

- Max 4K model: Added correct support for minor hardware changes (power
  control of the built-on fan) in the recent batches of Max 4K (which are
  shipped starting with May/2019).

- Amlogic models: DSD audio playback (ISO, DSF, DFF) is now supported.
  Known limitations: only stereo DSD is supported; audio file should not be
  too long (maximum supported duration is approximately 67 minutes).

- Amlogic models: Improved support for playback of WavPack (.wv) lossless
  audio files.

- Amlogic models (latest generation only: tv174c, tv175e, tv175f, tv175p):
  Added support for launching HTML applications (which can use Dune JS STB
  API) not only via /config/stb_home mechanism (as was supported before),
  but also from PHP plugins.

- All models: Implemented subtitle synchronization correction function
  (same as was previously available on Sigma models, with an improvement
  that synchronization correction is applied to each subtitle track
  individually).

- All models: The setting "Setup / Playback / Control / UP/DOWN buttons"
  now has an additional possible choice "Show playlist menu", which can be
  convenient when watching TV channels, watching TV series, or listening
  music playlists.

- All models: "Movies" menu: Updated per-years categories, added category
  "2019+".

- All models: PowerPoint presentations in PPTX format (.pptx file
  extensions) are now also supported (in addition to previously supported
  PPT format).

- All models: "Android applications" menu now includes a preinstalled item
  for "START.RU" VOD service ( https://start.ru ), which automatically
  installs and launches AndroidTV version (optimized for TV screen) of
  START.RU Android application.

- All models: Kartina.TV application updated to include some new features,
  improvements and fixes which were previously implemented in Kartina.TV
  STBs.

- All models: Small improvements and performance optimizations for TV
  plugins (improved loading of icons and EPG information).

- Some other minor improvements/fixes.

This version is exactly the same as the version 190412_0053_r13 with just
one change: fix for the problem that the player could hang during boot
sometimes.

This version adds a lot of new features such as UltraHD (BD4K) BD Menu (for
Realtek models), Netflix 5.1 audio support (for Realtek models), CUE sheets
supports, improved support for various music formats (WavPack, APE, FLAC),
various improvements in the music player, various improvements related to
the use of Hi-Fi audio output (for Max 4K and Ultra 4K models), "TV" menu
item, initial setup wizard improvements, and various other improvements.
NOTE: There were big changes in the core parts of the firwmare, so some
functions may be potentially broken in this version.

- New feature: A new graphical design for the internal audio player: now it
  shows a bigger album picture, with the information about track / album /
  artist below it (similarly to how "Now Playing" screen looks in the new
  Dune Control mobile app), and uses a new background picture.

- New feature: Screensaver is now supported in the internal audio player
  (same as was previously implemented on Sigma platforms).

- New feature: Added support for CUE sheets (same as was previously
  available on Sigma-based models) in internal player.

- New feature: Added a decoder for WavPack audio files (same as was
  previously available on Sigma-based models) in internal player.

- New feature: Realtek models: Added a support for playback of audio files
  in APE (Monkey's Audio) format (same as was previously available on
  Sigma-based models) for internal player. (On Amlogic models, APE playback
  was already supported.

- New feature: Realtek models: Added a new decoder for FLAC audio files
  (same as was previously available on Sigma-based models) in internal
  player, for improved compatibility with various FLAC file format
  variations. This in particular fixes problems with impossibility to time
  seek in some FLAC files. (On Amlogic models, there were no such
  problems.)

- New feature: Added a new main screen item "TV" which can be used as a
  convenient shortcut for quick start of the preferred TV application. The
  TV application can be any Dune HD application or any Android application.
  Added a feature for automatic searching of suitable community TV
  applications in Internet (similarly to how comminity Movies extensions
  are searched). The new setup section "Setup / Applications / TV" can be
  used to modify reconfigure "TV" item and to hide it.

- New feature: The initial setup wizard now has "auto" and "manual" modes,
  "auto" mode tries to avoid asking any questions and configure everything
  automatically. No questions are asked in case of Ethernet connection, and
  only Wi-Fi network is asked to be configured in case of Wi-Fi connection.

- New feature: The initial setup wizard now allows to skip network
  configuration by choosing "None" option.

- Improvement: Added a special optimization which disables Android feature
  to automatically scan of all the connected user storage devices for media
  files (which can be used by some Android applications). This Android
  feature was almost never useful, but was causing unneeded background
  activities and system load (especially when a huge HDD with a lot of
  files is attached), which could nevatively affect the performance of the main
  functionality of the player.

- Improvement: Added a special optimization which disables Android feature
  to automatically create Android system folders and files (used by some
  Android applications) on the connected user storage devices. This Android
  feature was almost never useful, but was causing unneeded writes to user
  storage devices and appearance of undesired files on the storage devices.
  Now such folders and files are created only on a dedicated partition of
  the internal flash memory.

- Realtek models: New version of BD Menu playback engine:

    - New feature: BD Menu playback mode now supports Ultra HD BD images
      (BD4K).

    - New feature: When using the new Dune Control mobile app, in BD Menu
      playback mode, the name of the currently played file is shown in the
      mobile app.

    - New feature: When using the new Dune Control mobile app, in BD Menu
      playback mode, it is now possible to time seek (change playback
      position) in the mobile app; also the current playback position in
      the mobile app is now displayed more correctly.

    - Improvement: Improved support for remote controls with a reduced set
      of buttons:
        - Playback menu can now be shown by first pressing INFO RC button
          to show INFO OSD and then pressing POP UP MENU RC button.
        - Playback can now be stopped by choosing "Exit player" action in
          the playback menu.

    - Improvement: Optimized the performance of handling of BD Menu for
      some BD images, some BD images and some BD scenes in some BD images
      now start faster.

    - Bugfix: Some BD images did not work correctly in some cases.

    - Bugfix: When starting BD Menu playback simultaneously with the
      internal player working in background mode, a hint about TOP MENU RC
      button could be wrongly displayed on the screen.

- New feature: Realtek models: When using Netflix application,
  multichannel (5.1) audio playback is now supported.

- New feature: Amlogic models: when playing IPTV stream via HTTP/TS or HLS
  media streaming protocol, the user can not record the currently played
  stream to the local storage by pressing "REC" RC button (same as it was
  previously implemented on Sigma based models).

- New feature: Amlogic models: the use can now see the current bitrate of
  the currently played media stream in the INFO OSD menu (same as it was
  previously implemented on Sigma based models).

- Improvement: Amlogic models: Improved playback of HLS streams in some
  cases.

- Improvement: Kartina.TV application updated to include some new features,
  improvements and fixes which were previously implemented in Kartina.TV
  STBs.

- Improvements for PHP plugins and PHP API:

   - Added "style=smart_label" feature for button GUI controls.

- Updated/improved UI translations for some languages.

- Some other minor improvements/fixes.

NOTE: The main feature of this firmware update is the support for the new
mobile app ("Dune Control"). It does not include the support for BD4K menu
and the support for CUE in the internal player -- these features will be
included into next versions.

- New feature: Added support the new mobile app ("Dune Control"):
    - Main new features of the new mobile app:
        - Navigator (new):
            - Browse and choose media content via Dune UI shown directly on
              your mobile device.
            - Access local and network sources, Favorites, Recent, My
              Collection, Movies, Dune HD PHP plugins, etc.
            - The menu shown on the mobile device mirrors the menu shown on
              the TV screen.
            - Enter text into text fields in Dune UI using native keyboard
              on your mobile device.
            - Photo viewer mode: view photos from the Dune HD device on the
              mobile device, control photo slide show.
        - Now Playing (new):
            - See the information about the currently played media content,
              including (when available) movie poster, movie title, music
              cover, music album/artist/track information.
            - Control the playback (play/pause, stop, previous/next,
              playback position, volume).
        - Remote (similar as in the old mobile app):
            - Fully replaces the standard IR remote control.
            - Uses Wi-Fi to connect to the local network.
            - Automatically searches for Dune HD devices in the local
              network.
            - Allows to control multiple Dune HD devices and easily switch
              between them.
    - More information and mobile app download:
        - http://dune-hd.com/dunecontrol/

- New feature: Added support for music tags and covers (same as it was
  implemented previously on Sigma-based models.

- New feature: Added support for chapters in MKV files (same as it was
  implemented previously on Sigma-based models.

- New feature: Added simple parental control mechanism for file browser.
  Put "pin_code = NNNN" line into "dune_folder.txt" file in any folder to
  protect this folder by the specified pin code.

- New feature: It is now possible to add the following items to Favorites
  menu: network folders, storages, "Internal Memory" folder.

- New feature: Recent menu now shows movie posters for files which are
  recognized as movies (works when the file was recognized as a movie when
  the file was added to Recent menu).

- New feature: When viewing Movie description in the Movie screen, it is
  now possible to move focus into the description area by pressing RIGHT
  button, and then scroll through the description via UP/DOWN buttons.
  (Helpful when using remote controls w/o P+/P- buttons.)

- New feature: Realtek models: Added automatic detection of the encoding of
  external subtitles, similarly to how it was implemented previously on
  Sigma-based models.

- New feature: Realtek models: The setting "Setup / Audio / Digital audio
  output mode" now have 3 possible choices: "Auto", "PCM (decode)",
  "Original (bitstream)" (default is "Auto").
    - "Auto": use PCM or Bitstream on HDMI output based the capabilities of
      the connected HDMI equipment (automatically detected via HDMI EDID);
      use Bitstream on S/PDIF output.
        - This choice should be suitable in most cases.
    - "PCM (decode)": use PCM on both HDMI and S/PDIF outputs.
        - This choice is useful to force PCM on HDMI output when the
          connected HDMI equipment works incorrectly and provides wrong
          EDID information, or when the connected S/PDIF receiver does not
          support bitstream audio formats (Dolby/DTS), or when it is
          desired to decode bitstream audio formats (Dolby/DTS) on the
          media player side for any other reason.
    - "Original (bitstream)": use Bitstream on both HDMI and S/PDIF
      outputs.
        - This choice is useful to force Bitstream on HDMI output when the
          connected HDMI equipment works incorrectly and provides wrong
          EDID information.

- New feature: Realtek models: Added new setting "Setup / Audio / Maximum
  digital outputs sample rate" with possible choices "Auto" and "192 KHz"
  (default is "Auto" when "Digital audio connector" setting is set to
  "HDMI", "192 KHz" when "Digital audio connector" setting is set to
  "S/PDIF").
    - "Auto": the system automatically detects the maximum allowed sample
      rate based on HDMI EDID information.
        - This choice usually should be used when audio is output via HDMI.
    - "192 KHz": the system allows output of up to 192 KHz sample rate via
      S/PDIF even if HDMI EDID information does not allow 192 KHz.
        - This choice is useful when outputting video directly to a HDMI TV
          (which does not support 192 KHz) and simultaneously outputting
          audio via S/PDIF to an A/V receiver, given that the used A/V
          receiver and the used S/PDIF cable support 192 KHz.

- Improvement: Movie posters are now always displayed with the
  correct/original aspect ratio (previously movie posters could be slightly
  stretched); GUI layout of the screens with movie posters is slightly
  modified correspondingly.

- Improvement: The special support for launching playback via an external
  SPMC/KODI application can now be used not only with SPMC version 16.x (as
  before), but also with SPMC version 17.x and with KODI of any version. If
  any of these alternative SPMC/KODI versions is installed by the user (and
  no other SPMC/KODI versions are installed), the installed version will be
  used (instead of automatically installing SPMC 16.x, as took place
  before). NOTE: The default SPMC 16.x should not be installed or should be
  deleted (if it was installed) in order to use this feature.

- Improvement: Improved support for USB keyboards.

- Improvement: My Collection: when choosing a folder to add to My
  Collection, "Add to collection" action is now always available via POP UP
  MENU. (Helpful when using remote controls w/o SELECT button.)

- Improvement: RC button presses are now better handled during initial
  setup wizard in some cases.

- Improvement: Kartina.TV application updated to include some new features,
  improvements and fixes which were previously implemented in Kartina.TV
  STBs.

- Improvement: Ultra 4K: In Audio Setup, in ESS DAC source setting,
  "Internal source" renamed to "Media player" for better clarity.

- Bugfix: Ultra 4K and Max 4K: When Hi-Fi audio output (XMOS) is used,
  Hi-Fi audio output may become not working in some cases when using
  HiByMusic external app and after that using another player.

- Bugfix: Ultra 4K and Max 4K: When Hi-Fi audio output (XMOS) was enabled,
  and "Digital audio output mode" setting was set to "Bitstream", Hi-Fi
  audio output did not work for bitstream audio formats (Dolby/DTS). Now,
  when Hi-Fi audio output (XMOS) is enabled, the media player automatically
  decodes bitstream audio formats (Dolby/DTS) not depending on "Digital
  audio output mode" setting.

- Bugfix: Realtek models: Stability improvements. Fixed the problem which
  could cause frequent "Application stopped" errors and other system
  instabilities in some cases.

- Bugfix: Realtek models: When Bitstream audio output was enabled, output
  of AAC audio could not work in some cases.

- Bugfix: Realtek models: It was impossible to configure some 4K video
  modes when using specific 4K HDMI equipment which does not fully support
  all HDMI 2.0a features (such as Epson 8300/9300 projectors).

- Bugfix: Realtek models: Switching subtitles could not work in some cases.

- Bugfix: Realtek models: Some HTTP/TS streams could not be played
  correctly (playback restarts and hangups could happen) in some cases.

- Bugfix: Realtek models: When CEC was enabled, TV wakeup could not work
  properly on exiting software standby mode in some cases.

- Bugfix: Amlogic models: Fixed problem with unneeded CPU usage when CEC
  was disabled.

- Bugfix: Amlogic models: Fixed problem that an external storage could not
  be mounted in some cases (because of a problem when attempting to check
  it for filesystem errors)

- Bugfix: Amlogic models: Fixed problem with DHCP client working
  incorrectly in some cases (network connectivity could be lost after a
  while in some cases).

- Bugfix: Amlogic models: Fixed problems with playback of network streams
  in some cases.

- Bugfix: Amlogic models: Some HEVC video files could not be played.

- Bugfix: Amlogic models: When video mode was set to Auto (EDID), this
  could work incorrectly when auto framerate was used in some cases.

- Bugfix: Amlogic models: Extra unneeded HDMI reinitialization could take
  place during boot.

- Bugfix: Traveler: Battery status could be indicated wrongly after
  power-on in some cases.

- Bugfix: When playback was started by IP Control command and screensaver
  was active, screensaver was not cancelled.

- Bugfix: Errors during playback of catchup TV streams could be handled
  wrongly in some cases (restoring Live TV playback instead of restoring
  catchup TV playback).

- Bugfix: Some HLS streams could not be played.

- Bugfix: Fixed problem that navigation buttons (left/right/up/down) did
  not work via IP Control in mouse emulation mode.

- Bugfix: Fixed problem that long-press of POWER RC button was wrongly
  detected faster than in 2 seconds in some cases.

- Bugfix: POP UP MENU could work wrongly in text edit fields in some cases.

- Bugfix: "Play with..." function could work incorrectly in some cases and
  could crash in some cases.

- Bugfix: When Composite video output was used, Setup menu could crash in
  some cases.

- Bugfix: Office files (such as .xlsx) were wrongly not recognized as
  office files in some cases.

- Bugfix: Icons shown in Favorites menu could become incorrect in some
  cases.

- Bugfix: "dune_firmware.dff" file was wrongly highlighted as audio (SACD
  DFF) file.

- Bugfix: GUI hint about D button could be shown incorrectly in some cases.

- Improvements for PHP plugins and PHP API:

    - New feature: Added support for color button actions without captions
      in control folders and regular folders.

    - Bugfix: Parameters for handle_user_input in control dialogs could be
      handled wrongly in some cases.

    - Bugfix: P+/P- buttons could not work correctly in cntrol dialogs in
      some cases.

    - Bugfix: Restoring GUI state in could work wrongly in some cases.

    - Bugfix: When the playback of the current playlist list item (e.g. TV
      series episode) finished in plugin playback mode, and the main menu
      was shown, the system wrongly did not automatically start the
      playback of the next playlist item.

- Improvements in IP Control protocol:

    - IP Control protocol extended with a lot of new features to support
      the new mobile app. In particular, added support for getting detailed
      information about the current UI state, and for controlling the UI
      state, to allow external applications to implement external browsers
      for Dune UI. For more information, see the description of protocol
      version 5 here:
        - http://dune-hd.com/support/ip_control/dune_ip_control_overview.txt

- Updated/improved UI translations for some languages.

- Some other minor improvements/fixes.

This version is a minor update, it includes:

- Various UI improvements to better support remote controls w/o 0..9,
  SELECT, SETUP buttons (such as the new Dune HD Bluetooth remote control).

- New feature: The setting "Setup / Playback / Control / Stop by RETURN"
  can be used to configure the behavior of RETURN button. The default
  setting is "Yes" (helpful when using remote controls w/o STOP button).
  The setting "No" is helpful when using remote controls with STOP button
  and when the user prefers the old behavior of RETURN button.

- New feature: The setting "Setup / Playback / Control / P+/P- buttons for
  files" can be used to choose "Time seek" (old) or "Switch files" (new)
  behavior. By default the behavior is now "Switch files" (which means
  switch to next/previous file in the playlist, same as when using
  NEXT/PREV buttons). Helpful when using remote controls w/o PREV/NEXT
  buttons.

- Improvement: Kartina.TV application updated to include some new features
  which were previously available only in Kartina.TV STBs and to support
  some changes on Kartina.TV server.

- Some other minor improvements/fixes.

- New feature: BD3D is now supported in full Blu-ray menu mode too (in
  addition to BD Lite mode, which was supported for BD3D before).
    - Additionally, full Blu-ray menu playback engine reworked and
      optimized to better handle fast forward and rewind, for various other
      playback improvements, for better compatibility with some discs.
    - Note: BD4K is still supported only in BD Lite mode and is not
      supported in full Blu-ray menu mode (work on this is in progress).

- New feature: Office files in formats ".ppt", ".pdf", ".doc", ".docx",
  ".xls", "xlsx" can now be opened directly from the file browser just by
  pressing ENTER on these files. A suitable application is automatically
  launched to open them (and automatically installed if it is not installed
  yet).

- New feature: Added the integration of the famous HiByMusic application
  for playback of audio files:
    - A special TV-optimized version of HiByMusic application (which can be
      fully controled via RC) is installed automatically when needed.
    - HiByMusic application can be launched for playback of audio files in
      various ways -- via POP UP MENU / "Play with..." action, via the new
      setting "Setup / Playback / Parameters / Player for audio files",
      etc.
    - When HiByMusic application is playing audio in background (after
      exiting it via TOP MENU RC button), it can be stopped via STOP RC
      button in Dune HD UI.

- New feature: DSD audio files in DSF and DFF formats can now be launched
  directly from the file browser just by pressing ENTER on these files.
  HiByMusic application is automatically launched to play them (and
  automatically installed if it is not installed yet).

- New feature: When attempting to play SACD ISO (DSD ISO) audio files or
  CUE audio playlist files, a recommendation to use HiByMusic application
  is shown (with the option to directly launch the application) (after that
  these files should be manually found and launched by the user inside
  HiByMusic application; unfortunately, HiByMusic application does not
  support direct launch-file action for these file types).

- New feature: Added a new setting "Setup / Playback / Parameters / Player
  for audio files". May be helpful to use a specific player (e.g.
  HiByMusic) for audio files by default (a an alternative to pressing POP
  UP MENU and then choosing "Play with..." action).

- New feature: Added a new setting "Setup / Playback / Parameters / Player
  for AVI files". May be helpful to use a specific player (e.g. SPMC) for
  AVI files by default (a an alternative to pressing POP UP MENU and then
  choosing "Play with..." action).

- New feature: AVI files are now played by default via SPMC player, to
  workaround the problems with stuttering of AVI files (these problems with
  AVI files stuttering are caused by low level parts of RTD1295 SDK and may
  be fixed in a better way in future, but at the moment they can only be
  fixed by using an external player such as SPMC). In the use of SPMC
  player for AVI files is undesired, the previous behavior of using the
  internal player can be chosen via "Setup / Playback / Parameters / Player
  for AVI files" setting.

- New feature: When SPMC or KODI application is running in background
  (after exiting it via TOP MENU RC button), it can be stopped via STOP RC
  button in Dune HD UI.

- New feature: When using internal player, RETURN RC buttons works as STOP
  (except the case when TV playback is performed and RETURN button is
  configured to work as "Return to previous TV channel"). Helpful when
  using remote controls w/o STOP button.

- New feature: Video files with ".webm" extension can be played now
  directly from file browser.

- New feature: HTTPS media streams now can be played also via M3U files and
  via launch_media_url IP Control command.

  enter English text in text fields in Dune HD UI.

- New feature: PHP API: IP Control commands "light_stop" and
  "set_playback_state" can now be used when PHP plugin is working.

- New feature: PHP API: "update_epg" action can now used even when the main
  menu is shown over the playback.

- New feature: PHP and JS API: Added support to use Widewine DRM with DASH
  video streams from PHP plugins and HTML applications: the new dune_param
  parameters "drm_scheme" and "drm_license_url" can be used to specify the
  required Widevine DRM parameters.

- New feature: Debug dump file can now be generated not only by pressing
  REW or PAUSE button 3 times in the file browser (as before), but also by
  pressing POP UP MENU button, and then pressing TOP MENU buttons. Useful
  when there is no REW and PAUSE buttons.

- Improvement: Debug dump files now should be more useful and contain more
  complete information.

- Improvement: When Setting Reset is performed, this also resets OpenWRT
  settings (previously OpenWRT settings were not reset).

- Improvement: Recovery menu now provides an option to reset OpenWRT
  settings.

- Improvement: V+/V-/MUTE RC buttons now always control playback volume,
  even when playback is not started yet.

- Improvement: Volume control OSD UI improved to not show unneeded UI
  elements.

- Improvement: Volume control OSD UI now handles DOWN/UP buttons as
  MUTE/UNMUTE actions (useful when the used remote control does not have
  MUTE button) and handles LEFT/RIGHT buttons as V-/V+ actions (useful when
  volume control OSD UI is triggered not by V+/V- buttons but by some other
  buttons, and there is no V+/V- buttons). ENTER and RETURN can be used to
  hide volume control OSD UI w/o waiting for timeout.

- Improvement: When playing DASH video streams, the last bandwidth is now
  remembered to ensure more smooth playback start.

- Improvement: When playing DASH video streams, streams with errors (such
  as missing segments) are now played more smoothly.

  wrongly when "Software standby" setting was used -- "Power off" action
  was wrongly performed, which causes impossibility to power on the box via
  IP Control.

- Bugfix: Copying big files into "Internal Memory" folder could not work in
  some cases.
   - NOTE: To fix this problem, it is required to reset settings once after
     installing the new firmware (in order to reformat the internal flash
     memory partition).
   - NOTE: Resetting settings once after installing this firmware is
     recommended anyway, even if "Internal Memory" feature is not used.
     this will fix some problems in the internal flash memory partition
     which can potentially cause some instabilities.

- Bugfix: When "software standby" mode was used, HDMI output was only
  blanked but was not switched off completely.
