## data.table [v1.18.99](https://github.com/Rdatatable/data.table/milestone/37?closed=1) (in development)

### BUG FIXES

1. Fixed the compilation failure in v1.18.0 in some strict environments, e.g., FreeBSD, where the header file declaring the POSIX function `waitid` does not transitively include the header file defining the `siginfo_t` type, [#7516](https://github.com/rdatatable/data.table/issues/7516). Thanks to @jszhao for the report and @aitap for the fix.
