Tensorboard

Bug Fixes
- Relax restriction on protobuf dependency (6887)
- Update usage of numpy to reflect numpy 2.0 changes (6871)
- Fix stacking of notification dot (6875, thanks crisbeto)
- Fix setting dialog styling regression (6885)

The 2.17 minor series tracks TensorFlow 2.17.

Features
- Enable adding hparams columns in scalar data tables in Time Series dashboard (6737 accidentally omitted from notes in release 2.16.0)
- Usability improvements for runs table and hparams in Time Series dashboard (6837, 6839)
- Global pins: Store pinned cards in local storage, so they’d be pinned when similar experiments are loaded. (6850, 6819, 6821, etc)
- Handle large number of Hparams (6777, 6780, 6807)
- Infra: Reduce binary size of [`tensorboard-data-server`](http://pypi.org/project/tensorboard-data-server/) (aka “Rustboard”). (#6765, thanks Corwinpro)

Bug Fixes
- Text plugin: Preserve whitespace. (6833)
- Hparams plugin: load metrics when run name is “.” (6822)
- Resolved Graph plugin compatibility issues with Keras 3. (6759, 6823, 6761, 6857, etc. thanks mloc)
- Restricts the protobuf dependency to be < 5.0.0, due to a recent breaking change (see 6808 for details).
- Fixes internal flag wrapper class to not crash when its `__class__` attribute is accessed, which was blocking debugging with pyCharm (6751, thanks lostinplace)

Bug Fixes
- Remove dependency on tf-keras pip package. (6759)

Bug Fixes
- Depend on tf-keras instead of tf-keras-nightly.

The 2.16 minor series tracks TensorFlow 2.16.

Features
- Time Series dashboard:
- Improved sorting of runs whose names begin with integers. (6664)
- Improved hparams filtering. (6680, 6692)
- Usability improvements and fixes in runs table. (6656, 6658, 6678, 6736)
- Graph plugin:
- Improved support for dark theme. (6691, thanks tummala-manasa)
- Removed dependencies on `google-auth`, `google-auth-oauthlib`, and `requests` libraries. (6705)
- Relaxed restriction on protobuf dependency, given that issue protocolbuffers/protobuf13485 was fixed. (6660, 6746)

Bug Fixes
- Hparams plugin:
- Fixed Download data links. (6719 fixes 6088, thanks louis49)
- Time Series dashboard:
- Fixed color picker usability regression. (6682)
- Brings the `tensorboard-data-server` wheel into conformance with [PEP 600](https://peps.python.org/pep-0600/), enabling support for the `--load-fast` flag in systems with GLIBC >= 2.29. (Requires installing/updating package `tensorboard-data-server==0.7.2`) (#6636 fixes 6578)

Breaking Changes
- `tensorboard dev` subcommand will now show an error message without sending any requests, as our hosted service at http://tensorboard.dev has been shut down.
- Not quite a breaking change, but to something to be aware of: TensorBoard releases generally follow TensorFlow’s releases. However, while TF 2.16 will start using Keras 3 by default, TensorBoard plugins’ implementation remains with keras 2 support only. See keras-team/keras18467 for details.

Breaking Changes

- Updates restriction on protobuf dependency to avoid bad version while still
allowing newer versions.(6660 & 6746)
