snarkOS tag/v2.2.7

That tag is almost 1 year old; I'd recommend using the current mainnet branch instead.

@zosorock we might want to push some newer tags to avoid confusion in the future.

[AndreaLanfranchi]

Thank you for your response.
Seems like switching to mainnet branch allows a clean build.

Actually, as you mentioned, isn't probably better to state clearly that mainnet branch is current release ? (your latest release is tagged 2.2.7)

[ljedrz]

It is stated in the readme:

Start by cloning this GitHub repository:
git clone --branch mainnet --single-branch https://github.com/AleoNet/snarkOS.git

[AndreaLanfranchi]

I understand that but this, at least to me, sounds odd.
First thing I always look at and which I also find consistently in other projects is this

The instructions you linked do not state the difference amongst mainnet branch and a release.
A release is supposedly a stable version.

[ljedrz]

Indeed, and that's why I tagged the applicable member so this can be adjusted 👍.
