mrv2 v0.3.8

v0.3.8

• Changed language handling in preferences. Now the locale code is stored.
• Removed all languages except for English and Spanish. Note that on Windows,
  if you had Spanish selected, it will revert to English. You will need to
  change it once again.
• Added reporting of memory use to HUD.
• Added Cache in Gigabytes to Settings Panel. When this is non-zero the
  Read Ahead and the Read Behind are calculated automatically based on
  the Gigabytes number set here. It divides it by image size, pixel type,
  fps and number of active movies. It also takes into account audio, but
  poorly.
• Fixed a resizing issue on Python Panel, not resizing the tile group.
• Documented Python API in both English and Spanish, with Search browser.
• Fixed sorting of recent files so that they don't change order.
• Fixed reccent files to not list files that cannot be found on disk.
• Made recent files list the files in order of how they were loaded, with last
  loaded first.
• Fixed original pixel lookups on clips that have a pixel aspect ratio != 1.0.
• Fixed original pixel lookups on YUV420P_U16, YUV444P_U16 format.
  Missing testing YUV422P_U16, but it should work.
• Made audio volume and audio mute / track selection not active if the clip
  has no audio.
• Added number of Cache Ahead and Behind Video and Audio frames to HUD.
  If Ahead Video cache becomes 0 when playing forwards, playback will stop.
• Fixed Text tool input on Wayland.
• Removed libharfbuzz from the Linux distribution as it was causing trouble
  with some newer Linux distros.
• Added a Render->Black Background option to quickly switch from a gray
  background to a black background on images or movies that have an alpha
  channel.

mrv2 v0.3.7

v0.3.7

• Added a half OCIO default to handle OpenEXR half images.
• Added timeRange and inOutRange to timeline module.

  time/frame/seconds.
• Fixed timeRange conversion to string (str) and repr (repr).
• Fixed Presentation toggle from the menus and from the right mouse button menu.
• Added media.firstVersion(), media.previousVersion(), media.nextVersion(),
  and media.lastVersion() to move from one version of the clip to the next.
• Allowed saving of sequences if you use something like bunny.0001.exr.
• Allowed saving of .otio files with relative paths.
• Flushed the cout buffer.
• Added creating playlists from python.
• Fixed audio slider which would jump from 0 to 1 abruptly.
• Fixed resizing of panel windows when they were created first as windows,
  not from undocked.
• Windows now remember their undocked state even after being docked once.
• Added help text to viewport. Now it will report when you click once on the
  viewport to Play or Stop the playback.
• Switching languages on Windows now works properly, both from the command-line
  and from the GUI.
• Fixed a crash on exiting the application.
• Made upgrading mrv2 more painless, as it will now update the OCIO config
  automatically to the new version, unless the path does not contain mrv2.
• Removed the outdated nuke-default OCIO config, replacing it with OCIO2's
  cgstudio config.
• Added Cut/Copy/Paste to Python editor (it was possible before, but just
  from the keyboard shortcuts).
• Renamed Python Editor's Python menu to File.

mrv2 v0.3.6

• Fixed Python Editor crashes (memory trashing).
• Made Python Editor remember its text when closed and reopened.
• Fixed Python Editor's coloring sometimes getting mixed up.
• Improved Python Editor's tabulation when a colon ends the line
  (to handle for, def, class, etc).
• Fixed Color Panel that had gotten broken due to adding python.
• Added a contactSheet.py demo for showing all the layers of an OpenEXR image or
  sequence in Compare Tile mode.
• Fixed Compare Tile mode selection and unselection of multiple clips in Compare Panel.
• Made cmd.compare() use the item index instead of item itself to avoid
  confusion when the same file was loaded more than once.
• Made CompareMode be part of the media module instead of the timeline module.
• Made mrv2 exit cleanly once the process calls _wexecv on Windows.
• Fixed the bad release of mrv2 v0.3.5 on Windows which would open a command

  • Control the timeline.
  • Change colors and LUT config.
  • Compare two images and change the compare settings.
  • Change the layer of the image.
  • Change the R, G, B, A channels of the image.
  • Change the foreground (A) and compare (B) images either by index
    or by file media item.

  The modules are:

     	 import mrv2
	 from mrv2 import cmd, math, imaging, media, timeline

Full Changelog: v0.3.3...v0.3.4

mrv2 v0.3.3

v0.3.3

• Added a spin option to Environment Maps to instead of panning around with
  middle mouse, it allows you to push and spin in one direction.
• Added all licenses to docs/Legal.
• Fixed file attachments on Linux.
• Fixed unistaller on Linux to remove icon and desktop file from
  /usr/share/*.
• Fixed installer on Windows to not popup the file association panel if not
  requested to do so (it asks now, instead of listing as one the things to
  insall). This is better as it allows us to translate into other natural
  languages that part of the installer.
• Added Natural Language translations (.mo files). Currently only Spanish is
  provided.
• Added comprehensive documentation on how to translate mrv2 to other natural
  languages.
• Fixed a bug in thumbnails changing the group that it was attached. This
  would effect the FilesPanel, ComparePanel, and PlaylistPanel.

• Fixed a race condition in the mrv2 File requester when creating thumbnails.
  This was most noticeable on Windows, where the thumbnails would get corrupted.
• Fixed a thread crashing on Linux when creating thumbnails.

  selecting a new .ocio oonfig file.
• Made File/Open and Open button in the Files Panel open the movie and then
  play it if the Preferences' autoplay button is on.
• Fixed favorites directory in custom file requester not getting saved on Linux.
• Fixed xcb_ and _XRead multithread errors on custom file requester on Linux.
• Added stacktrace and signal handler routines on Linux and Windows.
• Fixed log window/dock to pop up when an error occurs.
• Mostly fixed audio problems on Linux when switching clips. There can still
  be issues, but it is a matter of switching the clip again to make it work.
• Fixed text tool not working in v0.3.2.
