• Change: model_path and log_path enclosed in single quotes separately
  "libvmaf='log_path=C\:/path/to/log:model_path=C\:/path/to/model.json'"

v1.1.0 beta 1

• New: OxyPlot library upgraded to version 2.1.0
  Much faster renderer used (vital when many long files analyzed in one go)

  They replace previously existed command line parameters "-save-results" and "-save-results-file="
• New: A number of distorted files displayed in program main window title

v0.9.9

• New: The best and the worst values per metric highlighted in the grid (#55)
• New: New project option: "Skip" -- a duration that will be skipped at the beginning of video stream
  Note: only a few small values are in dropdown as the skipping process is slow (#61)
• New: Metrics calculation time is measured and displayed in ToolTip (#62)
• New: Files on the list can be re-arranged using Drag & Drop

• Change: Timeout for process of getting supported VMAF model types increased from 2 to 5 seconds (this could help with #57)
• Change: Options "Scaling method" and "Write FFMpeg Commands in log" are program options now, not project options.
  So they are not stored in project file any longer.
• Change: Option "Analyze" renamed to "Duration"
• Change: Values in "Skip" and "Duration" dropdowns that will go out of ref's file duration marked in red
• Bugfix: Frames' Axe on plot not reset if calculation cancelled and no data gathered (#54)

v0.9.8

• New: Percentile 1, 5, 10, 25 calculated and displayed in metric value Tooltip (#25)

  It is used only if distorted file's resolution is not equal to reference file's resolution. Default -- bicubic.
• Change: Processes for getting ref's media info and ref's thumbnail are off-loaded to background process.
  So these processes are not blocking UI on startup any longer (#39)
• Change: UI: Block with options is resizable
• Change: UI: Block with ref file is resizable
• Change: UI: Minimum program windows width decreased
• Change: UI: Progress indicator is displayed while getting ref's thumbnail (#40)
• Change: UI: Progress indicator is displayed while getting files' media info (#38)
• Change: Timeout for process of getting ref's thumbnail increased from 3 to 5 seconds
• Change: Timeout for process of getting media info increased from 5 to 10 seconds (#36)

• Change: All FFMpeg commands logged now (if appropriate option is turned ON) (#30)

v0.9.5

• New: VMAF models types supported by FFMpeg (json or pkl) detected automatically on program startup (#10)
• New: Frames statistics (MeanA, MeanG, Min, Max, StdDevP), frame's info and bitrate added to CSV results file (#17)
• New: Bad frames could be extracted as png (#26)
• New: Ref's thumbnail shown in UI
• Change: Files list area is resizeable and all 12 files could be visible at once without scrolling (handy for taking screenshots)
• Change: FFMpeg process priority changed to "Below Normal" for all calls

v0.9.4

• New: Progress is shown in task bar (#20)
• Change: 5, 10, 15, 20, 30 minutes added to "Analyze" duration dropdown (#14)
• Change: FFMpeg external process timeout for getting media info increased from 2 to 5 seconds (should help with #19)
• Change: Program version number returned to title
• Bugfix: "Save Project As" not updating title (#21)

• Bugfix: Crash if integer returned by FFMpeg as frame metric value ("42", expected: "42.0")
• Bugfix: Crash when FFMpeg process finished prematurely with partial output
  On my system this was caused by combination of LAVSplitter + AviSynth + DirectShowSource(VP9 or AV1)
