This release brings a new feature: ability to keep updating PRs with new changes to the tracked project. That is, if niv-updater-action opens a PR, each subsequent call will keep updating the PR with newly added changes to the tracked project, until PR is closed. So, if you're tracking a fast changing project (for example, nixpkgs), but you're slow to merge the niv update PR, it will at least have the most recent changes.
