+- update to version 5.4.5:
+  * Bug fixes
+    + 1268: setup.py's extra_require parameter requires latest
+      setuptools version, breaking quite a lot of installations.
+
+- changes from version 5.4.4:
+  * Enhancements
+    + 1239: [Linux] expose kernel "slab" memory for
+      psutil.virtual_memory(). (patch by Maxime Mouial)
+  * Bug fixes
+    + 694: [SunOS] cmdline() could be truncated at the 15th character
+      when reading it from /proc. An extra effort is made by reading
+      it from process address space first. (patch by Georg Sauthoff)
+    + 771: [Windows] cpu_count() (both logical and physical) return a
+      wrong (smaller) number on systems using process groups (> 64
+      cores).
+    + 771: [Windows] cpu_times(percpu=True) return fewer CPUs on
+      systems using process groups (> 64 cores).
+    + 771: [Windows] cpu_stats() and cpu_freq() may return incorrect
+      results on systems using process groups (> 64 cores).
+    + 1193: [SunOS] Return uid/gid from /proc/pid/psinfo if there
+      aren't enough permissions for /proc/pid/cred. (patch by Georg
+      Sauthoff)
+    + 1194: [SunOS] Return nice value from psinfo as getpriority()
+      doesn't support real-time processes. (patch by Georg Sauthoff)
+    + 1194: [SunOS] Fix double free in psutil_proc_cpu_num(). (patch
+      by Georg Sauthoff)
+    + 1194: [SunOS] Fix undefined behavior related to strict-aliasing
+      rules and warnings. (patch by Georg Sauthoff)
+    + 1210: [Linux] cpu_percent() steal time may remain stuck at 100%
+      due to Linux erroneously reporting a decreased steal time
+      between calls. (patch by Arnon Yaari)
+    + 1216: fix compatibility with python 2.6 on Windows (patch by Dan
+      Vinakovsky)
+    + 1222: [Linux] Process.memory_full_info() was erroneously summing
+      "Swap:" and "SwapPss:". Same for "Pss:" and "SwapPss". Not
+      anymore.
+    + 1224: [Windows] Process.wait() may erroneously raise
+      TimeoutExpired.
+    + 1238: [Linux] sensors_battery() may return None in case battery
+      is not listed as "BAT0" under /sys/class/power_supply.
+    + 1240: [Windows] cpu_times() float loses accuracy in a long
+      running system. (patch by stswandering)
+    + 1245: [Linux] sensors_temperatures() may fail with IOError "no
+      such file".
+    + 1255: [FreeBSD] swap_memory() stats were erroneously represented
+      in KB. (patch by Denis Krienbühl)
+  * Backward compatibility
+    + 771: [Windows] cpu_count(logical=False) on Windows XP and Vista
+      is no longer supported and returns None.
