-Note: The legacy code discussed in `torchtext v0.7.0 release note <https://github.com/pytorch/text/releases/tag/v0.7.0-rc3>`_ has been retired to `torchtext.legacy <https://github.com/pytorch/text/tree/release/0.9/torchtext/legacy>`_ folder. Those legacy code will not be maintained by the development team, and we plan to fully remove them in the future release.

-[BC Breaking] Legacy
-====================
-
-In the v0.9.0 release, we moved the following legacy code to `torchtext.legacy <https://github.com/pytorch/text/tree/release/0.9/torchtext/legacy>`_. This is part of the work to revamp the torchtext library and the motivation has been discussed in `Issue #664 <https://github.com/pytorch/text/issues/664>`_:
-
-* ``torchtext.legacy.data.field``
-* ``torchtext.legacy.data.batch``
-* ``torchtext.legacy.data.example``
-* ``torchtext.legacy.data.iterator``
-* ``torchtext.legacy.data.pipeline``
-* ``torchtext.legacy.datasets``
-
-We have a `migration tutorial <https://colab.research.google.com/github/pytorch/text/blob/release/0.9/examples/legacy_tutorial/migration_tutorial.ipynb>`_ to help users switch to the torchtext datasets in ``v0.9.0`` release. For the users who still want the legacy components, they can add ``legacy`` to the import path.
-
-In the v0.10.0 release, we retire the Vocab class to `torchtext.legacy <https://github.com/pytorch/text/tree/release/0.9/torchtext/legacy>`_. Users can still access the legacy Vocab via ``torchtext.legacy.vocab``. This class has been replaced by a Vocab module that is backed by efficient C++ implementation and provides common functional APIs for NLP workflows.
