Missing release version number in <title> in the HTML User's Guide
See, for example, here: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/flags.html
The <title>
of that page is 6.6. Flag reference — Glasgow Haskell Compiler <release> User's Guide
.
It should use the actual version number (in this case, 8.2.1) instead of the <release>
placeholder.
