       * C library header wrappers are only partially implemented because features are missing from libc
       * Types from diagnostics library (`<exception>`, `<stdexcept>`, `<system_error>`) are implemented, but exception handling does not work
-  * FIXME: non-negative errno
+  * Previously, HelenOS used negative error codes, which made it difficult to align with the ISO C standard which mandates that the error constants are positive. In this release we therefore switch the sign. A nice summary of this refactoring operation is provided [https://le-jzr.github.io/helenos/c/errno/2017/12/11/abusing-type-checking-for-fun-and-profit.html here].
