MKVToolNix 59.0.0 Final + Portable (MKV 동영상 생성/편집/추출/합치기)

# Version 59.0.0 "Shining Star" 2021-07-10

## New features and enhancements

* mkvmerge: WebVTT parser: the parser now follows the specs' rules for parsing

timestamps more closely by being more lenient: it allows arbitrary number of

spaces & tabs at the start of the line & around the arrow; it allows any

number of digits for the hours. Part of #3139.

* MKVToolNix GUI: multiplexer: when adding a Blu-ray playlist without scanning

for other playlists the GUI will now look for disc library information & let

the user select which one to use if there's more than one entry. Implements

#3143.

* MKVToolNix GUI: multiplexer: added an option for sorting files & tracks by

track types when adding them to multiplex settings. The order is: video

first followed by audio, subtitles and other types. Files & tracks can still

be reordered manually later. The option is enabled by default & can be found

in the preferences → "Multiplexer" page → "Adding files" section. Implements
