v12.7.0

✨ Open files in SWMR (Single Writer Multiple Readers) mode by default

Thanks @MridulS !

v12.6.1

• 🐛 Relax version ranges of Jupyter Lab packages to support version ^4.5 #153 #154

v12.6.0

✨ Upgrade H5Web to v16

• 🎉 Support NeXus default_slice attribute
• 🎉 < NX Line > When auxiliary signals are present, show picker next to visualization tabs to allow showing/hiding any of the signals, including the main signal
• 🎉 < Line > Support piecewise constant interpolation
• < Line > Move Line/Points/Both control into new Aspect menu
• Always show all supported NeXus visualizations instead of only the one for the specified interpretation (e.g. both NX Line and NX Heatmap for 2D+ datasets)
• Use Opt instead of Alt in interactions help menu on Mac

For the full list of changes, please refer to the release notes for v16.0.0

✨ Upgrade H5Web to v16.0.1

• Improve fallback message when no visualization is available for the selected entity

v12.5.0

🧩 Support more file extensions

• Classic HDF5: .hdf, .hf5
• NeXus: .nx5
• JLD2: .jld2
• EBSD-HDF5: .h5ebsd, .edaxh5, .oh5
• DREAM.3D: .dream3d
• GEOH5: .geoh5
• Oxford Instruments NanoAnalysis: .h5oina
• AnnData: .h5ad

Upgrade to H5Web 14.0.1

• Put x-axis column first in NeXus CSV export for consistency with typical XY and XYE files
• Add column with x indices when exporting 1D dataset to CSV for consistency with typical XY files

Upgrade to H5Web 15

• ✨ < NX Heatmap, NX Line > Support NXdata group with mixed real and complex signals
• ✨ < Heatmap > Allow flipping heatmap along x and y axes when viewing complex dataset
• ✨ < RGB > The last dimension that holds the three channel values now appears in the dimension mapper as a locked dimension (i.e. so users know that it's there but cannot map an axis to it)

v12.4.0

Upgrade to H5Web 14

• ✨ < NX Line > Support CSV export — the following columns are exported, in order, when the corresponding datasets are present in the NXdata group: values, abscissas, errors, aux1, aux1 errors, aux2, aux2 errors, ...
• ✨ < Compound > Include field names when exporting to CSV
• ✨ < Matrix > Respect transposition when exporting 2D dataset/slice to CSV
• ✨ < Matrix, Compound > Replace Fixed-point notation with Exact notation in toolbar to allow viewing and copying exact values
• ✨ < Scalar, Matrix, Compound > Display int64 values with exact precision
• 🐛 Don't crash when switching to log scale while visualizing a dataset with a negative domain — fall back to the default domain [0.1, 1] so user can switch back to a supported scale
• 🐛 Fix broken layout when inspecting dataset with long attributes

For the full list of changes, please refer to the release notes.

NX Line CSV export	Exact notation	int64 with full precision

v12.3.0

Upgrade to H5Web 13

• ✨ Preserve dimension mapping and slicing when possible, notably when toggling inspect mode or selecting another dataset with the same dimensions
• ✨ Support visualizing enum datasets and signals
• ✨ Support variable-length datasets
• ✨ Support inspecting metadata of committed datatypes

For the full list of changes, please refer to the release notes.

• ✨ < Compound > Visualize compound scalar datasets
• ✨ < Raw > Add toggle to fit raw JPEG/PNG images to viewport (on by default)
• ✨ Make variable-length string types explicit in metadata viewer
• ✨ Allow inspecting HDF5 string padding metadata
• 🐛 < Raw > Disable dark mode on raw JPEG/PNG images
• 🐛 Don't capitalize attribute names in metadata viewer
