 Release Notes for Symbian Build System v2
 
-version 2.11.4
+version 2.12.0
+
+New Features:
+- New 'Patchable Constants' target type: TARGETTYPE pdll
+- Combine Linking and Postlinking into a single step - performance improvement.
+- Support exit codes from next version of the trace compiler which will issue them
+- New sbs_filter script and batchfile to ease the use of sbs_filter.py.  
+  Allows filters to be executed over a log after a build has been done.
+    e.g.
+
+  	sbs_filter --filters=FilterWhat < logfile.log 
+
+    (This runs a "--what" without regenerating any makefiles or reparsing
+    the matadata.)
+- New (beta) FilterWhatComp filter.  Simulates abld log output for
+  use with parse_what.pl for packing up zips by component.  Whatcomp output
+  uses the incoming epocroot value.  i.e. if epocroot is relative then so is
+  the what output.  e.g. if EPOCROOT=\ then the output will be of the form:
+
+	"\epoc32\release\armv5\...."  
+
+  If it's "..\myepocroot" then the output will be:
+
+	"..\myepocroot\epoc32\release\armv5".  
+
+  If it's absolute then the what output will also be absolute.
+- New FilterCheck filter.  This can be used with sbs_filter to perform the 
+  equivalent of --check using the log output from a build.  It is more
+  efficient than --check because the metadata is not parsed and no makefiles
+  are generated. e.g.
+
+	sbs_filter --filters=FilterCheck < logfile.log 
+
+- New (beta) graphical build visualisation tool (bin/timelines.py). 
+  Requires pygame and PyOpenGL. e.g.
+
+	python timelines.py < filename.log
+
+- New (beta) log analyser (recipestats.py) for recording the total time spent 
+  in each type of recipe in the build. e.g.
+
+	python recipestats.py < filename.log > stats.csv
+
+  The output is in CSV format.  
 
 Defect Fixes:
-fix for ARM9E + ARMV5 pre-processing confusion
+- fix for ARM9E + ARMV5 pre-processing confusion
+- SF bug 1606: template_ext.flm wrongly creates dependencies to OTHER_CFG targets
+- SF bug 1570: Adding then removing a capability can produce incorrect 
+  result: e.g. ALL TCB -TCB becomes ALL -TCB but it should be just ALL
+
+Other Changes:
+- Default to using Python 2.6.4 on windows (no change in compatibility with 
+  older versions of Python).
