History
=======
1.8 (2019-07-05)
-----------------
* Draw label text on image with bounding box provided.
* crc32c speed up (optional by installing crc32c manually)
* Rewrite add_graph. onnx backend is replaced by JIT to support more advanced structure.
* Now you can add_mesh() to visualize colorful point cloud or meshes.

1.7 (2019-05-19)
-----------------
* Able to write to S3
* Fixed raw histogram issue that nothing is shown in TensorBoard
* Users can use various image/video dimension permutation by passing 'dataformats' parameter.
* You can bybass the writer by passing write_to_disk=True to SummaryWriter


1.6 (2019-01-02)
-----------------
* Many graph related bug is fixed in this version.
* New function: add_images(). This function accepts 4D iamge tensor. See documentation.
* Make add_image_with_boxes() usable.
* API change: add_video now accepts BxTxCxHxW instead of BxCxTxHxW tensor.

1.5 (2018-12-10)
-----------------
* Add API for Custom scalar
* Add support for logging directly to S3
* Add support for Caffe2 graph
* Pytorch 1.0.0 JIT graph support (alpha-release)

1.4 (2018-08-09)
-----------------
* Made add_text compatible with tensorboard>1.6
* Fix the issue of strange histogram if default binning method is used
* Supports passing matplotlib figures to add_image()
* Resolve namespace confliction with TF tensorboard
* add_image_boxes function
* Supports custom timestamp for event

1.2 (2018-04-21)
-----------------
* Supports tensorshape information in graph visualization. Drop support for 0.3.1
* Adds add_video function

1.1 (2018-02-21)
-----------------
* Supports pytorch 0.3.1 (hacky)

1.0 (2018-01-18)
-----------------
* Supports graph (the pretty one)

0.9 (2017-11-11)
-----------------
* Supports markdown for add_text function
* It's ready to log precision recall curve (needs tensorboard>=0.4)
* Adds context manager for the SummaryWriter class

0.8 (2017-09-25)
-----------------
* Package name renamed to tensorboardX to fix namespace confliction with tensorflow's tensorboard
* Supports multi-scalars and JSON export
* Multiple Embeddings in One Experiment 
* Supports Chainer and mxnet

0.7 (2017-08-22)
-----------------
* remove tensorflow dependency for embedding function
* fixed incorrect image<->label pairing in embedding function (#12)
* unifies API call and adds docstring. Documentation is available at: http://tensorboard-pytorch.readthedocs.io/

0.6.5 (2017-07-30)
------------------
* add travis test (py2.7, py3.6)
* add support for python2 (in PyPI)

0.6 (2017-07-18)
-----------------
* supports embedding

0.5 (2017-07-18)
-----------------
* supports graph summary
* fixed np.histogram issue

0.4 (2017-07-12)
-----------------
* supports text summary

0.3 (2017-07-03)
-----------------
* supports audio summary

0.2 (2017-06-24)
