 2. Edit [lib/dap/version.rb](https://github.com/rapid7/dap/blob/master/lib/dap/version.rb) and increment ```VERSION```.  Commit and push to rapid7/dap master.
 3. Run `rake release`.  Among other things, this creates the new gem, uploads it to Rubygems and tags the release with a tag like `v<VERSION>`, where `<VERSION>` is replaced with the version from `version.rb`.  For example, if you release version 1.2.3 of the gem, the tag will be `v1.2.3`.
 4. If your default remote repository is not `rapid7/dap`, you must ensure that the tags created in the previous step are also pushed to the right location(s).  For example, if `origin` is your fork of dap and `upstream` is `rapid7/master`, you should run `git push --tags --dry-run upstream` to confirm what tags will be pushed and then `git push --tags upstream` to push the tags.
