+- update to version 4.0.0
+
+**Enhancements**
+
+- #523: [Linux, FreeBSD] disk_io_counters() return a new "busy_time" field.
+- #660: [Windows] make.bat is smarter in finding alternative VS install
+  locations.  (patch by mpderbec)
+- #732: Process.environ().  (patch by Frank Benkstein)
+- #753: [Linux, OSX, Windows] Process USS and PSS (Linux) "real" memory stats.
+  (patch by Eric Rahm)
+- #755: Process.memory_percent() "memtype" parameter.
+- #758: tests now live in psutil namespace.
+- #760: expose OS constants (psutil.LINUX, psutil.OSX, etc.)
+- #756: [Linux] disk_io_counters() return 2 new fields: read_merged_count and
+  write_merged_count.
+- #762: new scripts/procsmem.py script.
+
+**Bug fixes**
+
+- #704: [Solaris] psutil does not compile on Solaris sparc.
+- #734: on Python 3 invalid UTF-8 data is not correctly handled for process
+  name(), cwd(), exe(), cmdline() and open_files() methods resulting in
+  UnicodeDecodeError exceptions. 'surrogateescape' error handler is now
+  used as a workaround for replacing the corrupted data.
+- #737: [Windows] when the bitness of psutil and the target process was
+  different cmdline() and cwd() could return a wrong result or incorrectly
+  report an AccessDenied error.
+- #741: [OpenBSD] psutil does not compile on mips64.
+- #751: [Linux] fixed call to Py_DECREF on possible Null object.
+- #754: [Linux] cmdline() can be wrong in case of zombie process.
+- #759: [Linux] Process.memory_maps() may return paths ending with " (deleted)"
+- #761: [Windows] psutil.boot_time() wraps to 0 after 49 days.
+- #764: [NetBSD] fix compilation on NetBSD-6.x.
+- #766: [Linux] net_connections() can't handle malformed /proc/net/unix file.
+- #767: [Linux] disk_io_counters() may raise ValueError on 2.6 kernels and it's
+  broken on 2.4 kernels.
+- #770: [NetBSD] disk_io_counters() metrics didn't update.
