+- updated to version 0.52
+
+Core:
+ * po4a-translate complains if the input po file is outdated (deb#637288).
+ * teach po4a-updatepo about the --porefs options that was already documented.
+ * rename --porefs values after msgmerge option's name: noline->file
+   and none->never. (deb#775708).
+
+po4a:
+ * New option --no-update to not touch the po files. (deb#599179)
+ * Checking po file is fine. Failing if the file does not exist isn't.
+   (deb#858934)
+ * Check the validity of po files before using them (deb#855431)
+
+AsciiDoc:
+ * Properly deal with item text missing its leading indent.
+ * Allow empty attribute lists, by bexelbie.
+ * Further bug fixing to handle the git documentation.
+ * Fix some bugs, around style macros
+ * Correctly handle list literal paragraph
+ 
+Man:
+ * Add support for the tab(<character>) global option inside .TS/.TE.
+   Also tidy up trailing newline handling in text blocks: Since that
+   trailing newling must be there, no need to translate it explicitly.
+   (deb#847754).
+   
+Text:
+ * Add an option to treat Key/Value pairs as verbatim
+ * Add a neverwrap option to prevent any wrapping (deb#824753)
+
+RubyDoc:
+ * New module by Francesco Poli (deb#827936)
+ 
+Wml:
+ * Make title translatable.
+
+XML:
+ * Add an option to escape all quotes, for android.
+ * Add an option to not wrap attributes.
+
