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

    Returns list of releases of the given version.

    Args:
      parent: string, Required. The version, which owns this collection of releases. Format: {product}/platforms/{platform}/channels/{channel}/versions/{version} (required)
      filter: string, Optional. Filter string. Format is a comma separated list of All comma separated filter clauses are conjoined with a logical "and". Valid field_names are "version", "name", "platform", "channel", "fraction" "starttime", and "endtime". Valid operators are "<", "<=", "=", ">=", and ">". Channel comparison is done by distance from stable. must be a valid channel when filtering by channel. Ex) stable < beta, beta < dev, canary < canary_asan. Version comparison is done numerically. Ex) 1.0.0.8 < 1.0.0.10. If version is not entirely written, the version will be appended with 0 for the missing fields. Ex) version > 80 becoms version > 80.0.0.0 When filtering by starttime or endtime, string must be in RFC 3339 date string format. Name and platform are filtered by string comparison. Ex) "...?filter=channel<=beta, version >= 80 Ex) "...?filter=version > 80, version < 81 Ex) "...?filter=starttime>2020-01-01T00:00:00Z
      orderBy: string, Optional. Ordering string. Valid order_by strings are "version", "name", "starttime", "endtime", "platform", "channel", and "fraction". Optionally, you can append "desc" or "asc" to specify the sorting order. Multiple order_by strings can be used in a comma separated list. Ordering by channel will sort by distance from the stable channel (not alphabetically). A list of channels sorted in this order is: stable, beta, dev, canary, and canary_asan. Sorting by name may cause unexpected behaviour as it is a naive string sort. For example, 1.0.0.8 will be before 1.0.0.10 in descending order. If order_by is not specified the response will be sorted by starttime in descending order. Ex) "...?order_by=starttime asc" Ex) "...?order_by=platform desc, channel, startime desc"
      pageSize: integer, Optional. Optional limit on the number of releases to include in the response. If unspecified, the server will pick an appropriate default.
      pageToken: string, Optional. A page token, received from a previous `ListReleases` call. Provide this to retrieve the subsequent page.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Response message for ListReleases.
      "nextPageToken": "A String", # A token, which can be sent as `page_token` to retrieve the next page. If this field is omitted, there are no subsequent pages.
      "releases": [ # The list of releases.
        { # A Release is owned by a Version. A Release contains information about the release(s) of its parent version. This includes when the release began and ended, as well as what percentage it was released at. If the version is released again, or if the serving percentage changes, it will create another release under the version.
          "fraction": 3.14, # Rollout fraction. This fraction indicates the fraction of people that should receive this version in this release. If the fraction is not specified in ReleaseManager, the API will assume fraction is 1.
          "fractionGroup": "A String", # Rollout fraction group. Only fractions with the same fraction_group are statistically comparable: there may be non-fractional differences between different fraction groups.
          "name": "A String", # Release name. Format is "{product}/platforms/{platform}/channels/{channel}/versions/{version}/releases/{release}"
          "pinnable": True or False, # Whether or not the release was available for version pinning.
          "serving": { # Represents a time interval, encoded as a Timestamp start (inclusive) and a Timestamp end (exclusive). The start must be less than or equal to the end. When the start equals the end, the interval is empty (matches no time). When both start and end are unspecified, the interval matches any time. # Timestamp interval of when the release was live. If end_time is unspecified, the release is currently live.
            "endTime": "A String", # Optional. Exclusive end of the interval. If specified, a Timestamp matching this interval will have to be before the end.
            "startTime": "A String", # Optional. Inclusive start of the interval. If specified, a Timestamp matching this interval will have to be the same or after the start.
          },
          "version": "A String", # String containing just the version number. e.g. "84.0.4147.38"
        },
      ],
    }

`list_next()`

    Retrieves the next page of results.

            Args:
              previous_request: The request for the previous page. (required)
              previous_response: The response from the request for the previous page. (required)

            Returns:
              A request object that you can call 'execute()' on to request the next
              page. Returns None if there are no more items in the collection.
