ruslan piskarovHi @gisle,
I remember this was discussed here https://www.drupal.org/node/2268995#comment-8947111.
I do not understand about the different types of licenses, so I re-read your advice and fix it in the next few days.
Thank you for your care.

gisleIt would be nice if you could add the missing attribution text to the project's README.txt. I've updated the issue summary with exact instructions about what you need to do.
There is no need to replace or remove the
icons.pngyet. Yours is not the only project that uses third party content, and we're reviewing the policy. One possible outcome of the review is that this shall be allowed.I've set status to "Postponed" for now. I'll get back when the policy review is completed (which will probably take some time).

gisleFixed typo.
Comment #4
gisleSplit policy and attribution issues.

ruslan piskarovHi @gisle,
I fixed it in the brunch 7.x-1.x.
Now I want to push these changes to the tag 7.x-1.0 and what I'm doing wrong :-(
or
I got the fatal error.
Maybe I should create a new 7.x-1.1 tag?
Sorry for such a question. This is my first module and I have a little experience work with git + drupal repo.
Comment #7
gisleYou must create a new tagged release (i.e. 7.x-1.1). You should never delete an existing tag or push to a release with the same number as one that already exists. There is no need to clone anything or to "cherry-pick" to do what you want. Assuming the HEAD of your local repo have the right version of README.txt (and it looks correct, I briefly inspected the HEAD of 7.x-1.x you pushed about two hours ago), you just create a new tag and push it.
First, make sure you're on branch
7.x-1.x. I.e.git statusshould report:If that is not what the status-command tells you, stop and ask here before proceeding.
When the status is clean, do the following:
Now the new tagged release should exist in your remote repo.
You can now click on "Add new release" at the bottom of your project page to get the 7.x-1.1 release packaged and a download link to it placed on the the project page (packaging takes 5-10 minutes).

ruslan piskarov@gisle,
The new 7.x-1.1 tag and release was created.
Thank you very much.
Comment #9
gisleSetting status back to "Postponed" to await outcome of site-wide policy review process.
Comment #11
gisleThe Drupal Git Repository Usage policy has been changed.
The very hard restrictions on including 3rd party assets has been lifted, and been replaced with the much more reasonable:
The README contains the required documentation. No action is required by the maintainer.
