This is a feature and bugfix release.

• Increased GLib minimum version to 2.58 (released in 2018).

• New options: --files=FNAME and --files0=FNAME. These allow reading lists of input files from a file or standard input. Paths can be separated by newlines or a zero byte (--files0). These options can be specified multiple times.

• New option: --link=[auto|on|off]. When used with --label, this controls whether each label should be an OSC 8-style hyperlink to its input file.

• Multiple files can now be decoded in parallel. This greatly speeds up grid mode on multi-core systems. Controllable with --threads.

• ConHost support was removed due to incompleteness and lack of interest.

• Image loaders:

  • Added support for CoreGraphics loaders on MacOS (@saitoha).
  • Added support for HEIF files on all platforms.

• Terminal support:

  • Improved detection of ghostty inside tmux (reported by @timsofteng).
  • Added support for GNU/Hurd console.

• Tests:

  • Expanded symbol matching tests with more cases and detailed diagnostics.
  • Added a test for CLI tool return values in various scenarios.

  293 Don't leave stdin in non-blocking mode (found by @YanceyChiew).
