Since questions about Magento 2 are popping up lately, I think we need a way to organize the tags for them.
I don't think a tag magento2-pre-alpha is enough. Like @Dan says here
Features in it can change daily, stuff removed, stuff added. It is very likely that questions that would be asked about "How can this be done", "How is this implemented" etc... would have different answers once the full version is released.
and I agree.
If you take a look at versions 220.127.116.11-dev45 and 18.104.22.168.-dev46 you can see huge differences.
Almost any answer for questions pre-dev46 may now have close to 0 value.
I suggest that beside the magento2-pre-alpha tag we should also add tags with the versions: 22.214.171.124-dev46.
Waiting for other opinions.
