 retroshare (0.5.3-0.XXXXXX~YYYYYY) YYYYYY; urgency=low
 
+  * Improvements
+     - Big cleaning of style sheets
+        * Moved some internal stylesheets to the file Standard.qss.
+        * Set the built-in stylesheet "Standard" as default for new profiles.
+        * Removed some unnecessary style sheets.
+        * Added two internal stylesheets:
+           - qss.default - This file is used as default for all stylesheets (e.g. the frames of 
+             the AvatarWidget) and can be overloaded from the selected stylesheet
+           - Standard.qss - The standard stylesheet for the current look of RetroShare. More internal stylesheets can be added.
+             The plan is to move nearly all internal stylesheets to the files Standard.qss/qss.default. After that the "empty" stylesheet 
+             should represent the system theme of the os.
+
+     - Added clear chat history to the context menu of the message text browser
+     - Added new base class HeaderFrame - image and text at top of the windows
+     - Enabled the RetroShare icon of the collection file dialogs. 
+     - estored SSLid to lower case in old certificate format.
+     - Removed dialog FriendRequest and use ConnectFriendWizard instead.
+     - Added new certificate format (Easier to parse/clean, more robust)
+        * checkbox for using old cert format in security page. Old format used by default, to avoid confusing newbees
+        * added new RsCertificate class to handle all certificate actions
+     - Several small tweaks to the gui
+     - Redesigned the Create Chat lobby dialog
+     - Fixed compilation with newer versions of libupnp, except for debian sid which uses a patched old version (crap!)
+     - update Spanish translation (from Senpai)
+     - Added a new page for user request to ConnectFriendWizard. The page is shown instead of the conclusion page when 
+       the user clicks on the certificate link in a message of type user request.
+     - Enabled icons for VOIP plugin
+     - Enabled display of plugin version in plugin items
+        * Hide the import/export button, and set the new identity CheckBox set checked, when start a new Profile 
+          generation from Profile Manager.
+        * Set PluginItem icon size to 24
+     - Added automatic clean of the friend certificate in ConnectFriendWizard.
+     - Fixed code for certificate link generation.
+     - Added new Chat style Bubble, generated by Victor for RetroShare
+     - Added a profile manager. Shoudl be useful for importing/exporting identities.
+
+  * Bugs
+     - fixed nasty bug causing crashes when syncing the keyring from disc
+     - added writing of public keyring to a tmp file + rename, to avoid corrupting it when RS stops during the whole operation
+     - Added a quick fix for the freeze of RetroShare when using a file dialog on Windows
+     - Fixed showup of self signatures in certificates that are not in the keyring already
+     - Added code to avoid corruption of bdboot.txt: first write to tmp file then move the file. Refers on 
+       Windows utf16ToUtf8 from libretroshare. This forward reference can be improved.
+     - Fixed bug with empty certificate strings when clicking on a certificate link with only a PGP id.
+     - Removed deadly assert in validate.c:338 causing crashes on error.
