 Revision history for Perl extension Time::HiRes.
 
+1.54
+	- Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep
+
+1.53
+	- Windows: higher resolution time() by using the Windows
+	  performance counter API, from Jan Dubois and Anton Shcherbinin.
+	  The exact new higher resolution depends on the hardware,
+	  but it should be quite a bit better than using the basic
+	  Windows timers.
+
 1.52
 	- In AIX (v?) with perl 5.6.1 the HiRes.t can hang after
 	  the subtest 18.  No known analysis nor fix, but added
