v1.5.5

[This is an update for users of nerves 1.5.x who can't update. Please use later releases if you're not in this situation.]

• Bug fixes
  • Fixes an issue where query parameters would be percent-encoded twice.
    Packages that use query_params argument option to artifact_sites could
    be impacted. For example, packages storing build artifacts in AWS S3
    require the X-Amz-Credential query parameter key whose value
    includes the reserved character /. This symbol is double encoded to
    %252F. This failed on systems with Erlang OTP-23.2 and above.
    See #604 for additional context.
