a very silly question, but the UI of RTD is confusing to me

 ![image](https://us1.discourse-cdn.com/flex002/uploads/haskell/original/2X/3/3a8312169f5dec6d79d59a5560fe90979aa54ace.png)  
how do I know that what is the version number of `alias=stable` or `alias=latest` ?  
like `stable` points to which version ?

[haskell-language-server — haskell-language-server 2.15.0.0 documentation](https://haskell-language-server.readthedocs.io/en/stable/) - this URL showing docs for `x1.y1.z1` or `x2.y2.z2` ?

I asked LLM, it said that if you hover on the the Tab, to see the Title, you can know

 ![image](https://us1.discourse-cdn.com/flex002/uploads/haskell/original/2X/b/b569a3900b3980f45cca18a5fef24b9a42f80709.jpeg)

so I am on the link [haskell-language-server — haskell-language-server 2.15.0.0 documentation](https://haskell-language-server.readthedocs.io/en/stable/)  
and in title I see `haskell-language-server - haskell-language-server 2.15.0.0 documentation`

Is this the relaible way to know 😅

I would guess that stable points to latest versioned docs release, and latest points to latest docs release (i.e. `master` branch of the repo).

Good question, and I don’t have a good answer 🤔

I can tell from the build logs

That stable is the last release and latest is master.

Perhaps we want to document this in our read-the-docs

WHY NOT MAKE IT EXPLICIT 😭

Does this mean stable = lastest ? = Latest GH release ?

latest follows master, so the current commit of master. stable /= latest. stable = latest GH release.

> WHY NOT MAKE IT EXPLICIT 😭

PRs welcome! Even though I am not sure what precisely you want to make explicit.

Not at this point in time, on attached screenshot you can see that latest was built more recently than 2.15.0.0 or stable. For example [latest](https://haskell-language-server.readthedocs.io/en/latest/configuration.html#sublime-text) it has extra paragraph compared to [stable](https://haskell-language-server.readthedocs.io/en/stable/configuration.html#sublime-text).

I found that behavior on latest and stable is documented in [readthedocs docs](https://docs.readthedocs.com/platform/stable/versions.html#versions-are-git-tags-and-branches) and it seems reasonable.
