v0.1.9

Upgrade H5Web

• ✨ < 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 for v14.0.0

NX Line CSV export	Exact notation	int64 with full precision

Other changes

• ✏️ Open output file after exporting dataset/slice to CSV or JSON #53

v0.1.7

Support JLD2 files

JLD2 is a file type natively created by the Julia programming language, which is heavily used in high-performance scientific programs. JLD2 makes heavy use of committed datatypes, which were poorly supported in H5Web and h5wasm.

• 🐛 These issues have been corrected, which means that JLD2 files can now be opened safely. #46 #47
• 🧩 Additionally, the extension is now configured to open .jld2 files automatically. #48

Upgrade H5Web

• ✨ 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 for v13.0.0

Preserve dimension mapping	Enum visualisation

v0.1.6

Upgrade H5Web

• ✨ Support virtual datasets with compressed local sources
• ✨ < NX Line, NX Heatmap > Support complex auxiliary signals
• ✨ < Line > Replace Autoscale toggle in toolbar with domain widget to allow customising the y axis domain
• ✨ < Compound > Visualize compound scalar datasets
• ✨ < Raw > Add toggle to fit raw JPEG/PNG images to viewport (on by default)
• 🐛 < Raw > Disable dark mode on raw JPEG/PNG images
• 🐛 Don't capitalize attribute names in metadata viewer
• ⚡ Reduce delay when slicing through a dimension whenever the target slice is already in the cache
• Make variable-length string types explicit in metadata viewer
• Allow inspecting HDF5 string padding metadata with h5grove (>=2.2.0), h5wasm and HSDS providers

For the full list of changes, please refer to the release notes for v12.0.0

Complex auxiliary signals	Scalar compound

v0.1.5

✨ Allow opening HDF5 files larger than 2 GB #41

Previously, when you tried to open a file larger than 2 GB, you would see an error in the H5Web webview editor. Now, you will be able to browse for the file manually from inside the webview, and in doing so, bypass the file size limitation.

v0.1.4

Upgrade H5Web

• ✨ < RGB > Allow flipping RGB visualizations on X and Y
• ✨ Add Nx Note visualization with support for JSON MIME type
• Improve support for empty datasets and attributes

For the full list of changes, please refer to the release notes for v11.2.0

RGB x/y flip	NX Note visualization

v0.1.3

Upgrade H5Web

• ✨ < Raw > Display JPEG/PNG images stored as opaque datasets
• 🐛 < Raw > Fix error when encountering bigints in compound datasets
• ✨ < Heatmap > Add toolbar control to flip X axis
• ✨ < NX Heatmap > Support NeXus auxiliary signals
• 5️⃣ Propagate HDF5 errors to viewer so they can be properly handled and displayed

For the full list of changes, please refer to the release notes for v11.1.0 and v11.1.1

Opaque JPEG/PNG	Flip X axis	Auxiliary signal selection

v0.1.2

• 📂 Add Blosc2 and Bitshuffle compression plugins.
• ✨ Bump H5Web from v10.1.0 to v11.0.0
  • [H5WasmProvider] Support lazy-loading Blosc2 and Bitshuffle compression plugins
  • [H5WasmProvider] Correctly parse the following advanced HDF5 types: H5T_OPAQUE, H5T_VLEN, and H5T_REFERENCE so they no longer appear as Unknown in the metadata viewer.
  • For the full list of changes, please refer to the release notes for v11.0.0

v0.1.1

• 🐛 Fix compression plugins failing to load under symlinked user directory.

v0.1.0
