The prior "official" version of ARC for D2 V1.33 was ARC V1.2.2.
The current "official" version is ARC V1.2.4. That's the version that is still on the public download page. It appears that it has a problem for folks whose room and speaker setup results in a "significant amount of bass EQ" for some speakers. The problem is that the overall bass level sent to those speakers ends up WAY too high. Based on the description of the problem it looks like it would only affect some users.
However ARC V1.2.4 has only one change that a D2 user might want -- it increases the range of subwoofer volume trim that ARC can Upload to the D2. If you do not need that fix, and if your ARC V1.2.2 setup is working fine at the moment, then you might as well just continue with ARC V1.2.2 for now. For AVM owners, on the other hand, ARC V1.2.4 is crucial -- it is the first ARC version to support the AVM units upgraded to add the second DSP hardware.
Anthem tech support runs a password protected download page where they put out beta (test) versions of new software. It is no big secret, but they keep it password protected to try to keep track of who might be using such versions. In the past, for example, they put up test versions that were designed for specific combinations of Anthem hardware version and certain source and display devices, knowing that they would not work with certain other combos. They would get the configuration details from the customer and only steer them to the test software if it was likely to work.
ARC V1.2.5 is on there now. It looks like it is a fix for the problem in ARC V1.2.4, but it is still early days yet.
IF you have deleted your ARC V1.2.2 setup and can't retrieve it from a backup, or if you need the subwoofer level Upload fix that V1.2.4 provides, then you will probably be fine with ARC V1.2.4 from the Anthem public download page. Or you could wait a few more days until we have more comments here either from folks using V1.2.4 or folks trying the test version V1.2.5. I've no idea how to predict whether V1.2.4 will give you a problem in your particular setup. Personally, my V1.2.2 is working fine and I'm not switching to V1.2.4 or V1.2.5 yet.
If you decide you need to go to V1.2.5, contact Anthem tech support and explain your situation and they will give you access to the password protected download page. But be aware that using beta software will sometimes result in unpleasant surprises, so don't be in a rush to use test software unless you really need to.
