Make clang-format break after the usage of C++ attributes

I'm using a deprecated attribute in my code and I haven't found a clang-format documented way to break after the C++ attribute. I would like that the definition of the do_not_use() function starts on a next line after the [[deprecated]] attribute.

Is there a way to break after C++ attributes?

Current state:

[[deprecated("Will be removed in version 2.3.0 as it doesn't support "
             "multi-threading processing. "
             "Use mt_process_info() instead")]] void
do_not_use()
{
    std::cout << "This function should not be used" << std::endl;
}

Desired state:

[[deprecated("Will be removed in version 2.3.0 as it doesn't support "
             "multi-threading processing. "
             "Use mt_process_info() instead")]]
void do_not_use()
{
    std::cout << "This function should not be used" << std::endl;
}

.clang-format:

Language: Cpp
Standard: c++20
AccessModifierOffset: 0
AlignEscapedNewlines: Right
AlignOperands: true
AllowShortFunctionsOnASingleLine: None
BreakBeforeBraces: Custom
BraceWrapping:
    AfterCaseLabel: true
    AfterClass: true
    AfterControlStatement: true
    AfterEnum: true
    AfterFunction: true
    AfterNamespace: true
    AfterStruct: true
    BeforeCatch: true
    BeforeElse: true
    IndentBraces: false
    SplitEmptyFunction: true
ColumnLimit: 100
Cpp11BracedListStyle: true
IncludeBlocks: Regroup
IndentAccessModifiers: true
IndentCaseLabels: true
IndentWidth: 4
PointerAlignment: Left
SpaceAfterTemplateKeyword: false
SpaceBeforeAssignmentOperators: true
SpaceBeforeCpp11BracedList: true
SpaceBeforeCtorInitializerColon: true
SpaceBeforeInheritanceColon: true
UseTab: Never

I've tried fiddling with the AttributeMacros and StatementAttributeLikeMacros clang-format settings but I haven't found a solution for stated problem.

Good news, a very recent clang-format commit (https://github.com/llvm/llvm-project/commit/a28f0747c2f3728bd8a6f64f7c8ba80b4e0cda9f) has added a new format option: BreakAfterAttributes.

Using BreakAfterAttributes: Always gives the output you want:

clang-format --style="{BreakAfterAttributes: Always}"

[[deprecated("Will be removed in version 2.3.0 as it doesn't support "
             "multi-threading processing. "
             "Use mt_process_info() instead")]]
void do_not_use() {
  std::cout << "This function should not be used" << std::endl;
}

Since this option is so new, it isn't yet in any released version, but it is guaranteed to be in version 16, or you may build clang-format from source.
