> [@idkpmiller](#): > > AmazonEchoControl plugin But that’s already a 2.x version binding and there is no legacy version of that binding. So that binding is under discussion because it will already be supported. So far the only legacy binding you’ve listed is MQTT but you’ve not sighted any specific capability gaps, just that _might_ be capability gaps. To the contrary as far as I’m aware, everything that the MQTT 1 binding could do the MQTT 2 binding supports as well, though per usual, _how_ it supports it might be pretty different. For examples: - REGEX Filter: [MQTT 2.5 M1+ How to implement the equivalent to MQTT1 REGEX filters](https://community.openhab.org/t/mqtt-2-5-m1-how-to-implement-the-equivalent-to-mqtt1-regex-filters/68350) - Event Bus: [Marketplace MQTT Event Bus](https://community.openhab.org/t/mqtt-2-5-event-bus/76938) - Generic MQTT Things cover the rest. All of the major bugs and problems with the MQTT binding have to do with Homie and HA automatic discovery which are features the MQTT 1 binding does not and could not support. So, unless there actually is some capability in MQTT 1.x that is not supported by MQTT 2.5 then what the argument really boils down to is “I want the maintainers to do and continue to do work in supporting 1.x version bindings so I don’t have to do any work to upgrade.” That isn’t a very compelling argument. If you do know of a capability that is missing from MQTT 2.5, then please file an issue. > [@idkpmiller](#): > > simple as we are not in a position to influence the outcome, by a simple poll, a developer with people like Kai and other sustaining members can force through what ever the current set of developers want. and the rest of the members really have little choice but to leave and go elsewhere if there are not onboard with the direction. The above poll was created by one of the active developers on OH and there have been replies from several other active developers on the openHAB project. From what I can tell, they are using this poll to prioritize their efforts to make sure that the minimal number of users are impacted with _a loss of capability_ when/if the 1.x compatibility layer is dropped. It is not a goal to ensure that there is no work that needs to be done by users to upgrade their 1.x bindings to 2.x versions. The architecture and how 2.x works is fundamentally different. Of course there is going to be some work. > [@idkpmiller](#): > > @Kai, can you advise if normal members are able to help with the direction how we go about doing this? The best way is to file issues. --- _[View the full topic](https://community.openhab.org/t/poll-which-oh1-x-addons-do-you-use/79121)._
