I reckon the answer to that is they will be released via the
beta website, however if you have the 'Switch' in
Preferences > General > Check for updates automatically on startup (weekly) ticked then you do not need to go to the beta website.
Conor will try to keep on top of Search Plug-in changes/problems as best he can and any macOS or iOS or tvOS that severely impact the current version 6 .* pedia's, though these updates will be few and possibly far between.
My current worry is that the 'Support' page/s is down on the Bruji website as well as the 'Doghouse' website is not currently working 100% considering this was to replace amazon as a search and gather website replacement. Though I believe the phpbb software needs to be updated and then adapted for Bruji requirements and that is no small task.
What will be, will be I suppose.
