# New features
|
|
|
|
|
|
|
|
This page is a placeholder for the eventual release notes.
|
|
|
|
|
|
|
|
Notable new features should come with release note updates. This is
|
|
|
|
done by creating a file snippet called `snippets/featurename.md` and
|
|
|
|
whose contents should look like this:
|
|
|
|
|
|
|
|
## Feature name
|
|
|
|
|
|
|
|
A short description explaining the new feature and how it should be used.

## Allow early return from a script
|
|
|
|
|
|
|
|
Added the function `subdir_done()`. Its invocation exits the current script at
|
|
|
|
the point of invocation. All previously invoked build targets and commands are
|
|
|
|
build/executed. All following ones are ignored. If the current script was
|
|
|
|
invoked via `subdir()` the parent script continues normally.

## Concatenate string literals returned from get_define
|
|
|
|
|
|
|
|
After obtaining the value of a preprocessor symbol consecutive string literals
|
|
|
|
are merged into a single string literal.
|
|
|
|
For example a preprocessor symbol's value `"ab" "cd"` is returned as `"abcd"`.
