This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

latkit@0.2.0

Minor Changes

• 9e476cc: Patches are bytes written in TypeScript, datasets change in place, and types come from latkit's schema both ways.

  • Added: Patch without WebAssembly (Patch.to(dataset), fromBytes, stream, extend), Data.read for latkit bytes and GeoJSON, data.snapshot(), queries' ids, total, and contains, outputs.ts (events, hits, stats, work, descriptions), and the documentation on Read the Docs.
  • Changed: data.apply(patch) changes the dataset in place; selections, row fits, select and delete events, and neighbors are row sets { data, table, ids }; Hit.mark is the mark's name; picks, locations, and layouts reject with timeout past a deadline; view.arrange() answers patches that name their datasets; field kinds name geometries (point, path, parts, polygons); pictures and videos no longer make the pipelines only input needs.
  • Renamed: put to replace, a query's where to filter, vertices' status to ring, rings and (off plots) trace to geometry, { colormap: value, map } to { colormap: map, value }, { scale: value, range } to { scale: [low, high], value }, grid pitches to { lines: { pitch } } and { dots: { pitch, snap } }, the 'earth' space to 'mercator', forms.ts to inputs.ts, and the error code load to io.
  • Removed: geojson() (Data.read), Data.fromBytes, patch handles and their destroy(), removeTiles (removeData), and bare numbers as row counts ({ count }).

• 9e476cc: Histories fetched in spans, and a frame's work follows what changed.

  • Added: time tiles. view.setTiles(name, url) opens a frames.json manifest, as latkit tile writes it, and fetches the spans of each sampled field's history its lines draw, at the detail they draw; a span still loading draws the coarser one above it.
  • Added: Patch.frames(table, field, { level, first }, at, values), a run of a sampled field's entries, as a time tile holds them.
  • Changed: errors reading JSON (scenes, cameras, fits, queries, rows, budgets, shots) name the path to what could not be read, such as scene.marks[2].vertices.color.
  • Changed: a patch evaluates only the pages it wrote; a transition evaluates once and blends each frame; rows drawn through tiles keep their places while the camera moves, so only arriving rows upload; the views of a Gpu share its budget, none planning past it together.

• 9e476cc: Views open in the time of their slowest pipeline with no frame held back and compile a third fewer pipelines, a patch costs the rows it changed, an edit of a diagram derives only what it reaches, text sets its fields on the GPU, geometry no longer answers the pointer unless asked, and diagrams draw what focus and drags mean.

  • Added: gpu.step(now) draws one frame now, and from the first no animation frames are asked for: a harness steps every frame itself; gpu.done() resolves once the GPU finished what was submitted, every readback landed, and every pipeline asked for compiled; gpu.landed() once work a view waits on lands after the call, or a view asks for a frame; view.wantsFrame.
  • Added: Work.late counts pipelines made without being asked for ahead; Waiting names compiling while the pipelines a view draws with compile.
  • Changed: a view asks for every pipeline its scene can use the first time it draws, and the browser compiles them off its GPU thread, the largest first: what it draws with all at once, the view drawing once that landed and keeping its last frame until then; what lights rows, probes, and answers picks a few at a time while frames draw, those waiting until it landed. No frame waits on a compile and nothing compiles where it is first used; complete waits for all of it.
  • Changed: the wasm is built without wasm-opt: as small over the wire, and views open sooner, the browser no longer compiling one giant function before their first frame.
  • Changed: one probe program per kind of mark answers the hover, picks, boxes, and locate, a step at a time: a page compiles about a third fewer pipelines and finishes opening sooner.
  • Changed: pick lists every row within reach, however many: a mark with more than 1,024 asks again with room for all of them.
  • Changed: text sets its distance fields on the GPU, every run set in a frame at once: the host only rasterizes, so labels fill in faster.
  • Changed: an edit of the values a diagram sizes and places rows by derives only the rows it wrote and what they reach: their boxes, the groups around them, and the wires they move. A text column written over codes only the rows written.
  • Changed: appends one after another to a table, as a stream of frames makes, write as one change.
  • Changed: unless pick says, rows that are things answer the pointer (vertices, edges, faces, a plot's traces) and geometry does not (areas, and lines along paths: coasts, borders, roads); pick: true makes a map's states or cells answer it.
  • Changed: a fit in a diagram frames its sheet, blocks and wires, at once without a readback; labels place once a fit has moved the camera; a mark with no rows no longer holds a fit back.
  • Changed: a patch of values in a table drawn in part writes only the rows whose values changed.
  • Changed: a drag event's position is where the dragged row goes: where it was grabbed, moved as the pointer moved, snapped to a diagram's dots when its grid snaps.
  • Changed: error paths run through the mark's kind, as its JSON does: marks[2].vertices.color.
  • Changed: the expression node types are named for what they are: FieldNode, ColorNode, … ColormapNode; a size in units is Units, your own colormap CustomColormap.
  • Fixed: lines seen up close no longer break up or vanish: a stroke reaching behind the eye is cut at the near plane instead of dropped, and its pixels are placed on screen however differently deep its ends lie.
  • Fixed: a hovered or selected group glows about its border instead of hiding what it holds; a lit block keeps its ports on top; wires stop at the rims of ports, so arrowheads show; rounded wires draw no stray junction dots; an unlabeled block makes room for its ports; great circles settle while their vertices animate.
  • Fixed: ports and group borders read against light themes.

• 9e476cc: Establish the LATK v1 format and tighten the npm, Rust, and CLI release contracts.

  • LATK now has a versioned header, 64-bit absolute sample indexes, explicit stored detail levels, and bounded decoding. Regenerate earlier unversioned files and time tiles from their source data.
  • Added latkit/core for DOM-free builders and CPU-only Rust expressions, queries, and data loading.
  • Fixed video cancellation and output cleanup, arbitrary query field names, URL resolution, and shared GPU device callback ownership.
  • Public declarations and API/CLI references now come from checked sources. Packages include consistent MIT licensing and third-party notices.
  • Releases verify the installed npm tarball and both Cargo artifacts, and resume missing publications safely before tagging.

Patch Changes

• 9e476cc: Keep font-atlas uploads in command order when several views render before one GPU submission.
  Multi-panel pictures and videos now retain every panel's titles, axis labels, and legends.
