# MSC2140

## V1 vs V2
In the [MSC2140](https://github.com/matrix-org/matrix-doc/pull/2140) the v2 prefix was introduced.

Default values:
```.yaml
matrix:
  v1: true   # deprecated
  v2: true
```

To disable change value to `false`.

NOTE: the v1 is deprecated, therefore recommend to use only v2 and disable v1 (default value can be ommited):
```.yaml
matrix:
  v1: false
```

## Terms

Example:
```.yaml
policy:
  policies:
    term_name: # term name
      version: 1.0 # version
      terms:
        en:  # lang
          name: term name en  # localized name
          url: https://ma1sd.host.tld/term_en.html  # localized url
        fe:  # lang 
          name: term name fr  # localized name
          url: https://ma1sd.host.tld/term_fr.html  # localized url
      regexp:
        - '/_matrix/identity/v2/account.*'
        - '/_matrix/identity/v2/hash_lookup'
```
Where:

- `term_name` -- name of the terms.
- `regexp` -- regexp patterns for API.
