The bot mistakingly thinks that v0.8.0-beta-rc2 comes after v0.8.0-beta.4. This will stop the automated updates. It can be removed once the final v0.8.0 is released.
With this update, renovate will only create PRs for package updates that cause build failures. Otherwise, it will just merge from the branch into master without a PR. This reduces the noise caused by the automated package updates. See https://docs.renovatebot.com/noise-reduction/
