Upstream ElectrumX has released v1.8.8, which includes name script support. (ElectrumX then subsequently released some other minor revisions, which seem to mostly be bug fixes; the latest release is currently v1.8.12.) If you run a Namecoin ElectrumX server, please consider upgrading to the latest ElectrumX release so that your users will be able to use name scripts.
(And a reminder that we need more ElectrumX instances… please consider running one if you have a server with spare resources!)
