+Changes in Bitbake 1.8.8:
 	- Rewrite svn fetcher to make adding extra operations easier 
 	  as part of future SRCDATE="now" fixes
 	  (requires new FETCHCMD_svn definition in bitbake.conf)
@@ -25,7 +27,15 @@ Changes in Bitbake 1.8.x:
 	- Fix int(0)/None confusion in runqueue.py which causes random gaps in dependency chains
 	- Fix handling of variables with expansion in the name using _append/_prepend
 	  e.g. RRECOMMENDS_${PN}_append_xyz = "abc"
-       
+	- Expand data in addtasks
+ 	- Print the list of missing DEPENDS,RDEPENDS for the "No buildable providers available for required...."
+ 	  error message.
+	- Rework add_task to be more efficient (6% speedup, 7% number of function calls reduction)
+	- Sort digraph output to make builds more reproducible
+	- Split expandKeys into two for loops to benefit from the expand_cache (12% speedup)
+	- runqueue.py: Fix idepends handling to avoid dependency errors
+	- Clear the terminal TOSTOP flag if set (and warn the user)
+	- Fix regression from r653 and make SRCDATE/CVSDATE work for packages again
 
 Changes in Bitbake 1.8.6:
 	- Correctly redirect stdin when forking
