+-----------------------

+### Changes
+- Add some `pkg-config` integration tips for developers using libuEv
+  with GNU autotools in their projects.
+
+### Fixes
+- Add missing `SFD_CLOEXEC` and `TFD_CLOEXEC` to signal and timer file
+  descriptors.  This prevents these file descriptors from "leaking" into
+  sub-processes of the parent thread.  The kernel will atomically close
+  these descriptors for forked-off children calling the exec*() family
+  of syscalls.
+- Minor coding style fixes and simplification of build scripts.

 introduced in [v1.2.1][].  Apologies for any problems this may cause!
 
 ### Changes
-
 - Change namespace for header files: `libuev/` to `uev/`, e.g. using
   `pkg-config` your C program must now `#include <uev/uev.h>`
 - Support for `EPOLLPRI` events for I/O watchers, thanks to Markus Svilans
