<br>
In #632, I propose amending the GHC2024 proposal to specify that the <br>
default language used by ghc/ghci when run directly will remain GHC2021 <br>
for now, since changing to GHC2024 is not backwards compatible. (This <br>
does not affect Cabal packages either way, since Cabal specifies its own <br>
default.)<br>

<br>
On the discussion thread, some people expressed a preference that GHC <br>
should default to the latest language edition anyway. There is also <br>
Richard's suggestion of wider changes of approach in #636. However, <br>
given that the GHC 9.10 fork date is fast approaching, introducing <br>
GHC2024 but not making it the default seems like the best short-term <br>
solution to me. We can always reassess our approach to this for future <br>
releases as part of the wider discussion.<br>
<br>
If you object to the proposed approach, please speak up ASAP. Otherwise <br>
I plan to merge in a week or so.<br>
<br>
Cheers,<br>
