Hello Sir
firstly all the ticket in our website has a reply, unless today's ticket .
for your question, we are updating add-on by add-on, we have more than 40 add-ons + more than 50 custom add-ons for client that should be upgraded to v5. we are doing our best to update as soon as possible, we regret that we causing you a trouble in your add-ons, wish add-on are trivial for you, i will push it in our backlog to speed the update for it.
generally a lot of add-on still working in v4 and v5.
