- Changed
  - **[BREAKING CHANGE]** removed post-processing options (Draco compression and binary output)
    - We encourage users to post-process the raw glTFs generated by this library in their own pipelines,
    using Node.js modules and CLI tools like [gltf-pipeline](https://github.com/AnalyticalGraphicsInc/gltf-pipeline)
    or [gltfpack](https://github.com/zeux/meshoptimizer#gltfpack)
    - See [test/remote-svf-to-gltf.sh](test/remote-svf-to-gltf.sh) for an example of such integration

## [1.2.1] - 2019-12-13

- Added
  - Scaling the output model based on SVF distance units (added by @dykarohora)

  - Missing folders when post-processing ([#11](https://github.com/petrbroz/forge-convert-utils/issues/11), fixed by @AlexPiro)

  - Filtering of objects to be included in the output glTF

## [1.1.1] - 2019-11-13

- Changed
  - When exporting to glTF+Draco, resources are no longer embedded into the manifest ([#7](https://github.com/petrbroz/forge-convert-utils/issues/7))

## [1.1.0] - 2019-11-08

- Added
  - Opt-in feature to move the model to origin
- Changed
  - Forge models are now reoriented based on their metadata to align with the glTF coordinate system (X=left, Y=up, Z=front)

> Note: scene hierarchies in the generated glTFs now contain two additional levels:
all scene objects are grouped into an _xform node_ that applies additional
transformations (for example, moving the model to origin), and the _xform node_
is a child of a _root node_ which transforms the entire scene to the glTF
coordinate system.

## [1.0.2] - 2019-11-01

- Removed
  - Support for sqlite output
    - Since [sqlite3](https://www.npmjs.com/package/sqlite3) is a native Node.js module, it was a [pain](https://css-tricks.com/what-i-learned-by-building-my-own-vs-code-extension/) to use this library in [vscode-forge-tools](https://github.com/petrbroz/vscode-forge-tools)
    - The experimental serialization/deserialization to/from sqlite is now developed in [forge-convert-sqlite](https://github.com/petrbroz/forge-convert-sqlite)

## [1.0.1] - 2019-10-31

- Fixed
  - Calls to `GltfWriter.prototype.write` now await postprocessing (if there's any)

## [1.0.0] - 2019-10-31

- Changed
  - **[BREAKING]** gltf/glb is now written with a single call (`await writer.write(svf, outputDir)`)
- Removed
  - `debug` dependency (using `console.log` instead)

## [0.8.0] - 2019-10-29

- Added
  - The `sqlite` flag now generates a sqlite manifest with both the glTF data and the property database
  - When deserializing sqlite back to glTF, you can now pass in a filter of dbids
    - The filter can be either a `SELECT dbid FROM properties WHERE ...`, or a list of dbids
- Fixed
  - Iterating of object properties
- Changed
  - Adding multiple SVFs into single glTF is now considered unsupported
    - Trying to do so will cause an exception in the `GltfWriter.write` method
