+
+2.7.0.0  Oct 2013
+
+        * Add new `Bool` flag to `ProcessStatus(Terminated)` constructor
+	indicating whether a core dump occured
+
+	* New functions in "System.Posix.Files(.ByteString)" for operating
+	on high resolution file timestamps:
+
+	 + `setFdTimesHiRes :: Fd -> POSIXTime -> POSIXTime -> IO ()`
+	 + `setFileTimesHiRes :: FilePath -> POSIXTime -> POSIXTime -> IO ()`
+	 + `setSymbolicLinkTimesHiRes :: FilePath -> POSIXTime -> POSIXTime -> IO ()`
+	 + `touchFd :: Fd -> IO ()`
+	 + `touchSymbolicLink :: FilePath -> IO ()`
+
+	* Export `SignalInfo(..)` and `SignalSpecificInfo(..)` as well as
+	the two `Handler` constructors `CatchInfo` and `CatchInfoOnce`
+	from "System.Posix.Signals".
+
+	* Don't export `seekDirStream` and `tellDirStream` if the
+	underlying `seekdir(3)`/`telldir(3)` system calls are not
+	available (as on Android).
+
+	* Fix library detection of `shm*` on openSUSE (#8350)
+
+	* Update package to `cabal-version >= 1.10` format
+
+2.6.0.1  Jan 2013
+
+        * Bundled with GHC 7.6.2
+        * Fix memory corruption issue in `putEnv`
+        * Use `pthread_kill(3)` instead of `raise(2)` on OS X too
+
+2.6.0.0  Sep 2012
+
+        * Bundled with GHC 7.6.1
+	* New functions `mkdtemp` and `mkstemps` in "System.Posix.Temp"
+	* New functions `setEnvironment` and `cleanEnv`
+	* New functions `accessTimeHiRes`, `modificationTimeHiRes`, and
+	`statusChangeTimeHiRes` for accessing high resolution timestamps
