please refer to [AliceVision changelog](https://github.com/alicevision/AliceVision/blob/develop/CHANGES.md).


## Release 2019.2.0 (2019.08.08)

Based on [AliceVision 2.2.0](https://github.com/alicevision/AliceVision/tree/v2.2.0).

Release Notes Summary:

 - Visualisation: New visualization module of the features extraction. [PR](https://github.com/alicevision/meshroom/pull/539), [New QtAliceVision](https://github.com/alicevision/QtAliceVision)
 - Support for RAW image files.
 - Texturing: Largely improve the Texturing quality.
 - Texturing: Speed improvements.
 - Texturing: Add support for UDIM.
 - Meshing: Export the dense point cloud in Alembic.
 - Meshing: New option to export the full raw dense point cloud (with all 3D points candidates before cut and filtering).
 - Meshing: Adds an option to export color data per vertex and MeshFiltering correctly preserves colors.

Full Release Notes:

 - Move to PySide2 / Qt 5.13
 - SfMDataIO: Change root nodes (XForms instead of untyped objects) of Alembic SfMData for better interoperability with other 3D graphics applications (in particular Blender and Houdini).
 - Improve performance of log display and node status update. [PR](https://github.com/alicevision/meshroom/pull/466) [PR](https://github.com/alicevision/meshroom/pull/548)
 - Viewer3D: Add support for vertex-colored meshes. [PR](https://github.com/alicevision/meshroom/pull/550)
 - New pipeline input for meshroom_photogrammetry command line and minor fixes to the input arguments. [PR](https://github.com/alicevision/meshroom/pull/567) [PR](https://github.com/alicevision/meshroom/pull/577)
 - New arguments to meshroom. [PR](https://github.com/alicevision/meshroom/pull/413)
 - HDR: New HDR module for the fusion of multiple LDR images.
 - PrepareDenseScene: Add experimental option to correct Exposure Values (EV) of input images to uniformize dataset exposures.
 - FeatureExtraction: Include CCTag in the release binaries both on Linux and Windows.
 - ConvertSfMFormat: Enable to use simple regular expressions in the image white list of the ConvertSfMFormat. This enables to filter out cameras based on their filename.

## Release 2019.1.0 (2019.02.27)

Based on [AliceVision 2.1.0](https://github.com/alicevision/AliceVision/tree/v2.1.0).

Release Notes Summary:
 - 3D Viewer: Load and compare multiple assets with cache mechanism and improved navigation
 - Display camera intrinsic information extracted from metadata analysis
 - Easier access to a more complete sensor database with a more reliable camera model matching algorithm.
 - Attribute Editor: Hide advanced/experimental parameters by default to improve readability and simplify access to the most useful, high-level settings.  Advanced users can still enable them to have full access to internal thresholds.
 - Graph Editor: Improved set of contextual tools with `duplicate`/`remove`/`delete data` actions with `From Here` option.
 - Nodes: Homogenization of inputs / outputs parameters
 - Meshing: Better, faster and configurable estimation of the space to reconstruct based on the sparse point cloud (new option `estimateSpaceFromSfM`). Favors high-density areas and helps removing badly defined ones.
 - Draft Meshing (no CUDA required): the result of the sparse reconstruction can now be directly meshed to get a 3D model preview without computing the depth maps.
 - MeshFiltering: Now keeps all reconstructed parts by default.
 - StructureFromMotion: Add support for rig of cameras
 - Support for reconstruction with projected light patterns and texturing with another set of images

Full Release Notes:
 - Viewer3D: New Trackball camera manipulator for improved navigation in the scene
 - Viewer3D: New library system to load multiple 3D objects of the same type simultaneously, simplifying results comparisons
 - Viewer3D: Add media loading overlay with BusyIndicator
 - Viewer3D: Points and cameras size are now configurable via dedicated sliders.
 - CameraInit: Add option to lock specific cameras intrinsics (if you have high-quality internal calibration information)
 - StructureFromMotion: Triangulate points if the input scene contains valid camera poses and intrinsics without landmarks
 - PrepareDenseScene: New `imagesFolders` option to override input images. This enables to use images with light patterns projected for SfM and MVS parts and do the Texturing with another set of images.
 - NodeLog: Cross-platform monospace display
 - Remove `CameraConnection` and `ExportUndistortedImages` nodes
 - Multi-machine parallelization of `PrepareDenseScene`
 - Meshing: Add option `estimateSpaceFromSfM` and observation angles check to better estimate the bounding box of the reconstruction and avoid useless reconstruction of the environment
 - Console: Filter non silenced, inoffensive warnings from QML + log Qt messages via Python logging
 - Command line (meshroom_photogrammetry): Add --pipeline parameter to use a pre-configured pipeline graph
 - Command line (meshroom_photogrammetry): Add possibility to provide pre-calibrated intrinsics.
 - Command line (meshroom_compute): Provide `meshroom_compute` executable in packaged release.
 - Image Gallery: Display Camera Intrinsics initialization status with detailed explanation, edit Sensor Database dialog, advanced menu to display view UIDs
 - StructureFromMotion: Expose advanced estimator parameters
 - FeatureMatching: Expose advanced estimator parameters
 - DepthMap: New option `exportIntermediateResults` disabled by default, so less data storage by default than before.
 - DepthMap: Use multiple GPUs by default if available and add `nbGPUs` param to limit it
 - Meshing: Add option `addLandmarksToTheDensePointCloud`
 - SfMTransform: New option to align on one specific camera
 - Graph Editor: Consistent read-only mode when computing, that can be unlocked in advanced settings
 - Graph Editor: Improved Node Menu: "duplicate"/"remove"/"delete data" with "From Here" accessible on the same entry via an additional button
 - Graph Editor: Confirmation popup before deleting node data
 - Graph Editor: Add "Clear Pending Status" action at Graph level
 - Graph Editor: Solo media in 3D viewer with Ctrl + double click on node/attribute
 - Param Editor: Fix several bugs related to attributes edition
 - Scene Compatibility: Improves detection of deeper compatibility issues, by adding an additional recursive (taking List/GroupAttributes children into account) exact description matching test when de-serializing a Node.
