UiPath periodically releases patches that include fixes and improvements when there is a business need. The documentation for a specific version is a reflection of the latest patch on that version. Product changes in-between patches can be checked in the release notes. For example, the documentation for 2021.4 Action Center illustrates the latest Action Center patch, namely 2021.4.1. For changes made in-between the different 2021.4 patches, check the release notes.
