Which branch or tag is deployed?

[your-diary]

I'm sorry if this is not the right place to ask a question about this repository.

Four months ago (May), I learned Swift 6.1 via the book.
Swift 6.2 had not been released yet at that time.

Now Swift 6.2 is released, so I want to learn the changes since the point I learned Swift 6.1.

Document Revision History is so high-level that I don't tell the actual diff.
So I want to do git diff, but which commits should I compare?

My first try was git diff swift-6.1-fcs swift-6.2-fcs, but this contained more diffs than I expected.
For example, swift-6.1-fcs doesn't include Implicit Constraints section but I'm 100% sure I read the section at that time because my learning note contains its URL.
So, at least, comparing something with swift-6.1-fcs is incorrect for my purpose.

Perhaps main branch is always deployed as soon as it is updated (even without GIt tag)?
(If so, I can just compare the current main with some older main.)

Each version of TSPL that was published has a corresponding tag in this list. If you remember the date you last read TSPL, you can find the corresponding tag from that list. New updates are published from the 'main' branch when new versions of Swift ship, and with beta versions of Swift. Not every Swift beta has a corresponding update to the book. If you were reading during the beta period, the revision history entry you last saw might have been combined. For each beta update, a new entry is added — and then for FCS, all of the beta entries are combined into a single revision history entry.

You can ask more questions in the Swift forums, where there's a section for documentation.

Looking at git blame, the Implicit Constraints heading was added by commit f055bc1, which was merged into 'man' by PR #351. That content first published in the beta 1 update of Swift 6.2, so the tag you want is probably swift-6.2-beta-1.

@amartini51
Thank you very much!

the tag you want is probably swift-6.2-beta-1.

Yes, this seems exactly what I was looking for.
