Dev-boringcrypto question

Hi Go team,

We are very interested in dev.boringcryptoX.YZ branches and I am trying to automate the build, test and promotion of these branches internally.

I read the document:

Is there a document that someone can point me to how these branches are created ?

Is there a way to determine if dev.boringcrypto.goX.YZ has been GA’ed, in the sense that active development has been completed, even a tag with the keyword “GA” would suffice.

Thanks in advance.
