MKVToolNix 96.0 “It’s My Life”

# Version 96.0 "It's My Life" 2025-11-08

## New features and enhancements

* all programs: added a command-line parameter `--no-bom` that disables
  writing byte order marks to text files encoded with one of the UTF
  variants. Implements #6166.
* MKVToolNix GUI: multiplexer: added variable `<MTX_CHAPTERS_FILE_NAME>` to
  the "run program after job completion" mechanism containing the absolute
  path to the chapters file name. Implements #6172.

## Bug fixes

* mkvmerge: OBU reader: fixed probing files in which the first frame ends
  after the 1MB mark, which is how big the memory buffer used for probing
  content is. Fixes #6165.
* mkvmerge: VobSub reader: VobSub `.idx` files that start with a byte-order
  mark (BOM) are now read again correctly. Fixes #6162.
* mkvextract: AV1/IVF: fixed inserting a temporal delimiter OBU at the start
  of each frame if there is none. Mostly fixes #6120.
* mkvextract: AV1/IVF: fixed a potential calculation error when deriving frame
  rate numerator & denominator from Matroska's default duration. Part of the
  fix of #6120.
* mkvextract: AV1/IVF: fixed calculation of IVF frame number calculation from
  Matroska's frame timestamps by rounding instead of truncating. Part of the
  fix of #6120.
