`list(parent, pageSize=None, pageToken=None, x__xgafv=None)`

    Lists the releases that have been created for the specified site or channel. When used to list releases for a site, this list includes releases for both the default `live` channel and any active preview channels for the specified site.

    Args:
      parent: string, Required. The site or channel for which to list releases, in either of the following formats: - sites/SITE_ID - sites/SITE_ID/channels/CHANNEL_ID  (required)
      pageSize: integer, The maximum number of releases to return. The service may return a lower number if fewer releases exist than this maximum number. If unspecified, defaults to 100.
      pageToken: string, A token from a previous call to `releases.list` or `channels.releases.list` that tells the server where to resume listing.
      x__xgafv: string, V1 error format.
