# spacy-legacy: Legacy functions and architectures for backwards compatibility

This package includes outdated registered functions for

[spaCy](https://spacy.io) v3.x, for example model architectures, pipeline

components and utilities. It's **installed automatically** as a dependency of

spaCy, and allows us to provide backwards compatibility, while keeping the core

library tidy and up to date. All of this happens under the hood, so you

typically shouldn't have to care about this package.

[![tests](https://github.com/explosion/spacy-legacy/actions/workflows/tests.yml/badge.svg)](https://github.com/explosion/spacy-legacy/actions/workflows/tests.yml)

[![pypi Version](https://img.shields.io/pypi/v/spacy-legacy.svg?style=flat-square&logo=pypi&logoColor=white)](https://pypi.org/project/spacy-legacy/)

## How it works

Whenever a new backwards-incompatible version of a registered function is

available, e.g. `spacy.Tok2Vec.v1` → `spacy.Tok2Vec.v2`, the legacy version

is moved to `spacy-legacy`, and exposed via [entry points](setup.cfg). This

means that it will still be available if your config files use it, even though

the core library only includes the latest version.

Legacy functions are exposed with the prefix `spacy-legacy`, e.g.

`spacy-legacy.Tok2Vec.v1`. When spaCy resolves your config and a function is not

available in the core library, e.g. `spacy.Tok2Vec.v1`, it will check if there's

a legacy function available and fall back to that. You can also explicitly refer

to legacy functions in your config, to indicate that a newer version is

available.
