+	Version 2.9
+
+	* luatexko.lua, luatexko.sty:
+	adapt to latex-base-dev's new shipout hooks;
+	adapt to luaotfload's (not yet released) new expansion feature;
+	center-align horizontal writing box inside vertical writing
+
+	* luatexko-normalize.lua:
+	use lua-uni-algos package, which means that normalization
+	will not be confined to Hangul characters but applied to
+	all the Unicode ranges.
