The published TSPL book on docs.swift.org has been updated for the Swift 6.3 release, but the swift-book repository still reflects the 6.3 beta state.

The swift-6.3-fcs tag is also missing.
This makes it difficult to reliably consume and archive the released Swift 6.3 book from the swift-book repository (for more details about why this is important, see here). Based on the commit history, merging from the release branch and pushing the swift-6.3-fcs tag should be all that's needed.
I've thought of creating a PR to reflect the changed state, but my guess is that this will complicate things even more. My understanding based on previous releases is that the tags and release updates are done locally and the local release branch is merged later on. For example, for the 6.2.3 release, the Docs were updated on December 12, 2025 but the merge commit was pushed on December 15, 2025.
I created an issue on Github last month, but posting here as well in case there's an easier way to get this issue resolved.
