MIQ 1.5.0

New features:

• Segmentation colouring for Finder thumbnails
• Support for the MIF Bit datatype (bit-packed masks).

Performance improvements:

• Segmentation colouring auto by default for preview and thumbnails.
• Improved handling of NaN and Inf voxels.

Fixes:

• Fixed MIF anatomical orientation ignoring the transform header, which could mislabel left/right on obliquely-transformed volumes.
• Minor GUI fixes in the main app

MIQ 1.4.1

Fixes:

• “Restore default settings” did not cover the “Voxel value” metadata setting.
• Multiple minor bug fixes

Other:

• Automatic update is now the default

MIQ 1.4.0

New features:

• (Automatic) in-place app updates using Sparkle

Improvements:

• Enhanced label file detection to minimize false-positives. Greyscale integer images with a narrow intensity range should now no longer be rendered as labels.
• Improved FreeSurfer LUT detection.
• Faster percentile windowing on large volumes
• Further tweaks for the upcoming macOS 27

Fixes:

• Fixed error handling when Github is not reachable for checking updates.
• Corrected large gzip decompression that could mis-render volumes over 4 GiB
• Fixed malformed headers that could crash instead of showing an error
• Fixed stale renders when a preview is dismissed mid-load

MIQ 1.3.0

Improvements:

• Updated the metadata panel layout to use two columns for better readability.

Fixes:

• Malformed or corrupted image files now fail gracefully instead of crashing the preview.
• The Settings window’s toolbar background no longer disappears when the pointer leaves the toolbar on macOS 26 and later.

MIQ 1.2.0 - Network enhancements

Performance improvements:

• Further improved behavior on network shares for large non-NIfTI files, since NIfTI already allows partial reads.
• In addition, for slow network shares, a new a setting to gate automatic previews of large non-NIfTI files.

Fixes:

• User inferface glitches fixed

MIQ 1.1.0

New features:

• Segmentation coloring: Applies a color LUT when a label file is detected. For aseg/aparc label files, it uses canonical FreeSurfer colors.
• Inspect the voxel value at the crosshair position (in interactive mode)

Performance improvements:

• Up to 50% faster rendering performance.
• Network shares: Faster initial preview of large 4D NIfTI files. The app now reads only the first volume up front instead of the entire file. Thumbnail generation on network shares is now configurable and off by default.

Fixes:

• Unresponsive fullscreen mode.
• Switched to significant digits instead of fixed decimals for displaying scaling.

Other:

• Initial compatibility with macOS 27 Beta 1, with minor remaining UI issues in the main app.

MIQ 1.0.0

New feature

Thumbnail renderer! Display an image slice as the file thumbnail/icon in Finder. Optional feature, off by default

Bug fix

Missing metadata line above Volume scrubber in 4D mode

MIQ 0.5.0

New features

• Support for previewing 4D files (volume scrubber)
• Usage tab in the main app, explaining the interactive controls.
• Per-volume intensity window setting

Improvements

• General performance and stability enhancements
• UI tweaks

MIQ 0.4.2

Performance improvements

• General optimizations, up to 2x render speed in testing
• Massive speed-up (up to 100x load speed) for large gzip-compressed 4D NIfTI files through partial decompression (for now only .nii.gz)
• Improved slice-scrolling behavior
• Instant interaction without clicking first

New feature

• Window/level adjustment via right-click and drag

MIQ 0.4.1 - Update checker

• Update checker in the main app
• Improved overlay color setting
