looping can be enabled for individual elements through a right-click option.

Bug fixes

- 965 - pr_curve_streaming_op no longer results in duplicate plots (PR 1053)

before doing `pip install tensorboard`. See "Known Issues" below if you run into
problems using TensorBoard after upgrading.

The 1.6 minor series tracks TensorFlow 1.6.

Highlights

- (Beta) New Profile dashboard, which provides a suite of tools for inspecting
TPU performance. See for details:
https://github.com/tensorflow/tensorboard/tree/1.6/tensorboard/plugins/profile
- (Alpha) New Debugger dashboard, which provides a visual interface to `tfdbg`,
the TensorFlow debugger. See for details:
https://github.com/tensorflow/tensorboard/tree/1.6/tensorboard/plugins/debugger

Known issues

- Package `tensorboard` is installed but command and/or module are missing or
have the wrong version - this may be due to conflicts with other packages that
provide `tensorboard` scripts or modules. Please uninstall *all* such packages
including `tensorboard`, `tensorflow-tensorboard` and `tb-nightly` and then
reinstall `tensorboard`.
- Bazel 0.9.0+ required to build from source - this change was necessary in order
to add support for building at Bazel 0.10.0 and above. Please update Bazel.

NOTICE: TensorBoard 1.6.0+ will move to the `tensorboard` package name on PyPI,
instead of using `tensorflow-tensorboard`. Only bugfix updates on 1.5.x will be
applied to the old package name. To upgrade to TensorBoard 1.6.0+ please *first*
`pip uninstall tensorflow-tensorboard` before doing `pip install tensorboard`.

The 1.5 minor series tracks TensorFlow 1.5.

Bug fixes

- 554 - line charts no longer "shrink" after run changes on other tabs
- 889 - fixed xComponentsCreationMethod default in vz-line-chart
- 898 - fixed offset of checkbox label in projector dashboard - thanks marcj
- 903 - disabled margin plot smoothing to avoid line going out of bounds
- 916 - made `futures` dependency py2-only to avoid install failures
- 924 - fixed graph dashboard bug causing blank PNG download and minimap
- 926 - made projector plugin API available in pip package

Documentation updates

- FAQ updated to describe custom scalars plugin use cases

The 1.5 minor series tracks TensorFlow 1.5.

Highlights

- New Custom Scalars dashboard, which can display configurable custom line and
margin charts based on the same data as the regular Scalars dashboard. See
for details: https://github.com/tensorflow/tensorboard/tree/1.5/tensorboard/plugins/custom_scalar
- Many projector plugin enhancements thanks to francoisluus, which enable
cognitive-assisted labeling via semi-supervised t-SNE
- t-SNE specific features: semi-supervision (811) plus perturb (705) and
pause/resume (691) buttons
