Hello,
I'm developing some custom plugins for CB, and I'd like to store also on the JED as on my website.
As the JED, from Jan 2017, has set as mandatory the Joomla Update System for all textensions published, there is a way to implement in CB dedicated plugins that updating system?
Or if now, can I in some ways enter automaticalli in DB table "#__update_sites" my daya, during the plugin installation process? Maybe using the "queries" tag?
I'm not albe to find a great new documentation for all the tags in xml file of of CB plugins.

Thanks for the help.
Greg

I'm sorry to reply but, as JED reports from last January it's mandatory for all new extensions:
Under the URL "extensions.joomla.org/support/knowledgebase/item/joomla-update-system-requirement/" is written what I'm saying.

New Listing Requirement: All extensions uploaded to JED after 10th January 2017 are required to use the Joomla Update System. This will help to ensure that site owners are always notified of when a new version of their installed extensions is available. Keeping extensions up to date can help to improve security.

Anyway I know and understand isn't possible for a CB plugin to be updated through Joomla update system, I just try to find a nice workaround for this. Something like to create a script to write on DB in the right table a new row to enter the address of update site for the CB plugin. Then of course, after the user is notified about the update, he should go manually to update the plugin through CB, but in this way the extension is listable on JED.
For this I was looking for some documentations to understand how to use the tags "quesies" and "database" in the xml files of CB plugins.
