    connection can be made.
    Allow connections to be added, updated, and removed while
    already holding the connection lock.

    Fixed the CSV writer to automatically detect headers.
DataProvider module
    Fixed conversion of soft binary, bool, float, int, and number
    "or nothing" types from an empty string to NOTHING.

    required (not-null) types.
    Fixed a bug handling the trunc option in mappers when bulk

    when an access token was acquired.

SalesforceRestClient
    Fixed a bug where the REST headers were not set up to accept
    JSON responses when the REST client was used with a token, this
    also caused breakage in the SalesforceRestDataProvider module.

    columns.

    Fixed support of nullable object properties.
Fixed bugs handling base64-URL-encoded strings.
