Julia v1.11 Release Notes
========================
New language features
---------------------
* `public` is a new keyword. Symbols marked with `public` are considered public
API. Symbols marked with `export` are now also treated as public API. The
difference between `public` and `export` is that `public` names do not become
available when `using` a package/module. ([#50105])
* `ScopedValue` implement dynamic scope with inheritance across tasks ([#50958]).
Language changes
----------------

loads, primarily to be used within JLLs ([#50074]).

write the output to a stream rather than returning a string ([#48625]).
