+Future Unicode update
+
+Tools simplified since the Unicode 6.1 update. See
+- http://site.icu-project.org/design/props/ppucd
+- http://bugs.icu-project.org/trac/wiki/Markus/ReviewTicket8972
+
+* Unicode version numbers
+- icutools/unicode/makedefs.sh was deleted, so one fewer place for version & path updates
+
+* file preparation
+- ucdcopy.py, idna2nrm.py and genpname/preparse.pl replaced by preparseucd.py:
+- ~/svn.icu/tools/trunk/src/unicode$ py/preparseucd.py ~/uni61/20120118 ~/svn.icu/trunk/src ~/svn.icu/tools/trunk/src
+- This writes files (especially ppucd.txt) to the ICU4C unidata and testdata subfolders.
+- Check test file diffs for previously commented-out, known-failing data lines;
+ probably need to keep those commented out.
+
+* PropertyValueAliases.txt changes
+- Script codes that are in ISO 15924 but not in Unicode are now listed in
+ preparseucd.py, in the _scripts_only_in_iso15924 variable.
+ If there are new ISO codes, then add them.
+ If Unicode adds some of them, then remove them from the .py variable.
+
+* UnicodeData.txt changes
+- No more manual changes for CJK ranges for algorithmic names;
+ those are now written to ppucd.txt and genprops reads them from there.
+
+* generate core properties data files (makeprops.sh was deleted)
+- ~/svn.icu/tools/trunk/dbg/unicode$ c/genprops/genprops ~/svn.icu/trunk/src
+
+* no more manual updates of source/data/unidata/norm2/nfkc_cf.txt
+- it is now generated by preparseucd.py
+
+* no more separate idna2nrm.py run and manual copying to generate source/data/unidata/norm2/uts46.txt
+- it is now generated by preparseucd.py
+- make sure that the Unicode data folder passed into preparseucd.py
+ includes a copy of http://www.unicode.org/Public/idna/6.1.0/IdnaMappingTable.txt
+ (can be in some subfolder)
+
+* generate normalization data files
+- ~/svn.icu/trunk/dbg$ export LD_LIBRARY_PATH=~/svn.icu/trunk/dbg/lib

+- ~/svn.icu/trunk/dbg$ bin/gennorm2 -o $SRC_DATA_IN/uts46.nrm -s $UNIDATA/norm2 nfc.txt uts46.txt
+
+* build ICU (make install)
+* build Unicode tools using CMake+make
+
+* new way to call genuca (makeuca.sh was deleted)

+ and in com.ibm.icu.dev.test.lang.TestUScript.java
+- 2 new script codes from ISO 15924 http://www.unicode.org/iso15924/codechanges.html

+ # First field: Code point
+ # Second field: Alias
+- to
+ # Each line has three fields, as described here:
+ #
+ # First field: Code point
+ # Second field: Alias
+ # Third field: Type
+- Also, the file previously allowed multiple aliases but only now does it
+ actually provide multiple, even multiple of the same type. For example,
+ FEFF;BYTE ORDER MARK;alternate
+ FEFF;BOM;abbreviation
+ FEFF;ZWNBSP;abbreviation
+- This breaks our gennames parser, unames.icu data structure, and API.
+ Fix gennames to only pick up "correction" aliases.
+ New ticket #8963 for further changes.

+- Unihan range end moves from 9FBB to 9FC3
+ search for both 9FBB (end) and 9FBC (limit) (regex 9FB[BC], case-insensitive)
+ + do change gennames.c
+
+* build Unicode data source code for hardcoding core data

+Unicode .icu files built to "\svn\icuproj\icu\uni51\source\data\out\build\icudt39l"
+Unicode .c source files built to "\svn\icuproj\icu\uni51\source\data\out\tmp"
+
+- copy the .c source files to C:\svn\icuproj\icu\uni51\source\common
+ and rebuild the common library
+
+*** Break iterators
+
+* Update break iterator rules to new UAX versions and new property values
+
+*** UCA
+
+* update FractionalUCA.txt and UCARules.txt with new canonical closure
+
+*** Test suites
+- Test that APIs using Unicode property value aliases (like UnicodeSet)
+ support all of the boolean values N/Y, No/Yes, F/T, False/True
+ -> TestBinaryValues() tests in both cintltst and intltest
+
+*** LayoutEngine script information
+* Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguage.h,
+ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (it also generates
+ScriptRunData.cpp, which is no longer needed.)
+
+The generated files have a current copyright date and "@draft" statement.
+
+* copy the above files into <icu>/source/layout, replacing the old files.
+
+Add new default entries to the indicClassTables array in <icu>/source/layout/IndicClassTables.cpp
+and the complexTable array in <icu>/source/layoutex/ParagraphLayout.cpp. (This step should be automated...)
+
+* rebuild the layout and layoutex libraries.
+
+*** Documentation
+- Update User Guide
+ + Jamo_Short_Name, sfc->scf, binary property value aliases
