+    - Book has now a downloadId, corresponding to the aria2 download id (if
+      exists)
+  * [API break] Manager class API has been updated :
+    - The manager is mainly use to fill a Libray from a "library.xml" file or
+      opds feed. Other operations (has removeBookById, setBookPath, filter, ...)
+      have been removed.
+    - The manager use a intermediate class (LibraryManipulator) to add book to
+      the library. This dependency injection allow caller code to hook the add
+      of a book to the library.
+    - The manager work on a existing Library. It doesn't how a internal
+      Library.
+  * [API break] OpdsDumper class API has been updated :
+    - dumpOPDSFeed method now take the list of bookIds to dump instead of
+      dumping all books in the library.
+    - OpdsDumper can now dump openSearch result information (total result
+      count, start index, ...).
+  * [API break] Common tools API has been updated :
+    - `base64_encode` and `base64_decode` take std::string as arguments.
+    - New `download` function in networkTools.h using libcurl.
+    - New `getDataDirectory` function in pathTools.
+    - Better `beautifyInteger` and `beautifyFileSize` functions.
+    - New `nodeToString` function serializing a pugi::xml_node to a string.
+    - New `converta2toa3` function to convert alpha2 language code to aplha3
+      language code.
