# Introduction

Bento 1.0.0 is alive!
GitHub Bento project
Tildegit mirror
Compared to the previous news, it received

* bento is now a single script, easy to package and add to $PATH. 
Before that it was a set of scripts with a shared shell files with
functions in it, not very practical…
* the hosts directory can contain directories with flakes in it, that
may contain multiple hosts, it’s now handled.  If there is no flake
in it, then the machine is named after the directory name
* bento supports rollbacks, if something is wrong during the deployment
then the previous system is roll backed
* enhancement to the status output when you don't have a flaked system,
as build are not reproducible (without efforts) we can't really compare
local and remote builds

```

* network measurements shown that polling for configuration changes
costs 5.1 kB IN and OUT
* many checks has been added when something is going wrong

# On step

It's a huge milestone for me, I thought it would be too much work to
get there, but in one week and 441 lines of shell, bento is a real
thing.
