+# v0.12.0 [unreleased]
+
+  Drop the license gem, entirely. This removes the last bit of DRM from mutants code base.
+  Mutant is *still* comercial software that requires payment if used on a commercial code base!
+
+  Migration:
+
+  * Commercial users: Add `usage: commercial` to your config file (or `--usage commercail` to your CLI)
+  * Opensource users: Add `usage: opensource` to your config file (or `--usage commercail` to your CLI)

 ## Licensing
 
-Mutant is commercial software, with a free usage plan for opensource projects.
+Mutant is commercial software, with a free usage option for opensource projects.
 
-Commercial projects have to acquire a license per developer, with unlimited repositories
-per developer. CI usage for licensed developers is included.
-
-Opensource projects have to acquire their free license per repository. That license will
-work for any contributor implicitly. Typically the project maintainer gets the license.
-
-The license distribution happens through the `mutant-license` gem. Mutant installs without
-that dependency, but will not be very cooperative unless `mutant-license` is also available.
-
-The license gem is dynamically generated per licensee and comes with a unique license gem source
-URL.
-
-After signup for a license the following has to be added to your `Gemfile` replacing `${key}`
-with the license key and `${plan}` with `com` for commercial or `oss` for opensource usage.
-
-```ruby
-source 'https://${plan}:${key}@gem.mutant.dev' do
-  gem 'mutant-license'
-end
-```
-
-The mutant license gem contains metadata that allows mutant to verify licensed use.
-
-For commercial licenses mutant checks the git commit author or the configured git email
-to be in the set of licensed developers.
-
-For opensource licenses mutant checks the git remotes against the licensed git repositories.
-This allows the project maintainer to sign up and not bother collaborators with the details.
-
-There are, apart from initial license gem installation, no remote interaction for
-license validation.
-
-### Getting an Opensource license
-
-As stated above: Opensource projects of any kind are free to use mutant.
-
-Just mail [me](mailto:mbj@schirp-dso.com?subject=Mutant%20Opensource%20License): Please
-include:
-
-* Just the git remote URL of your repository. Repository can be anywhere, must not be on Github, just has to be public.
-
-I do not need any more details.
+Commercial projects have to pay a subscription fee.
