 5. Locale changes
 
   - patches/locale_google.patch : Google's internal ICU locale changes
 
   - patches/locale1.patch :
       a. Exemplar character set changes for zh*, ja + 9 Indian locales
-      b. Minor fixes for Korean, a few Indic (AmPmMarkers) and
-      others (datetime format)
+      b. Minor fixes for Korean and Turkish
 
   - Locale build configuration files: To include the full locale data
     for Chrome's UI languages and the minimum locale data for other locales,
     add reslocal.mk or {trns,sprep,rbnf,coll}local.mk files to
     source/data/{coll,curr,lang.locale,curr,region,translit,zone,rbnf,sprep}.
 
     This along with #8 (data.build.patch), #3 (brkiter) and #4 (converter)
     cuts down the data size by ~ 11MB.
 
   - Run scripts/trim_data.sh : About 2.1MB data size reduction.
       a. Trim the locale data for Chrome's UI langauges :
          locales, lang, region, currency
       b. Trim the locale data for non-UI languages to the bare minimum :
         ExemplarCharacters, LocaleScript, layout, and the name of the
         language for a locale in its native language.
       c. Remove the legacy Chinese character set-based collation
          (big5han/gb2312han) that don't make any sense and nobdoy uses.
 
   - android/patch_locale.sh (to be run for Android build only):
       a. Makes changes to source/data/{curr,region,lang} to exclude these data
          except the language and script names of zh_Hans and zh_Hant.
       b. Remove exemplar cities in timezone data (data/zone)
       c. Keep only the minimal calendar data in data/locales
 
-  - Add tg.txt to source/data/locale source/data/lang to add the minimal locale
-    data necessary for the spellchecker. In both directories, add tg.txt to
-    reslocal.mk
+  - Add tg.txt, ckb.txt, and ku.txt to source/data/{locale,lang} 
+    with the minimal locale data necessary for spellchecker and 
+    and language menus.
 
 6. Timezone data update
   - Grab the latest version of the following timezone data files and
     put them in source/data/misc.
 
      metaZones.txt
      timezoneTypes.txt
      windowsZones.txt
      zoneinfo64.txt
