No tag release for the backends

Hi,

There is not tags created  for the asciidoctor-backend github repo :

host:~/Repos/Github/asciidoctor/asciidoctor-backends$ git tag -l
host:~/Repos/Github/asciidoctor/asciidoctor-backends$

Ticket created : https://github.com/asciidoctor/asciidoctor-backends/issues/115

Questions :
- Is it planned to create tagged versions ?
- Is the master branch the backends code (slim, haml, ...) that we can use with Asciidoctor 1.5 ?
- Are the templates of the master branch backward compatible with 1.0.4 ?

Regards,
