How to release a new version

1. Update config.json:

{
  "versions": {
+   "2.2.6": {
-   "2.2.4": {
      "tags": [
        "latest",
        "2",
        "2.2"
      ]
    },
+   "2.2.4": {},
    "2.2.2": {},
    "2.2.0": {},
    "2.0.14": {
      "tags": [
        "2.0"
      ]
    },
 

2. Add the new Dockerfiles:

$ dhbp build-and-push --dry --save 2.2.6

3. Update the tag list in README.md:

$ dhbp generate-tag-list-md

3. Commit, merge to master, and push with tags:

$ git add .
$ git commit -m "Add 2.2.6."
$ git checkout master
$ git merge develop
$ git tag 2.2.6
$ git push --all && git push --tags

4. Add the new release to regular builds: https://github.com/nim-lang-ci/docker-images-regular/wiki/How-to-release-a-new-version
