- The function cThread::Cancel() now only sets 'running' to false and does not actually kill the thread if the special value -1 is given (suggested by Udo Richter). - Changed the I18nNormalizeLanguageCode() check to also allow blanks (and all other printable characters) in the language codes (thanks to Boguslaw Juza for reporting that there are stations that use blanks in these codes). Blanks are replaced with underlines, so that all parts of VDR that rely on language codes to be one word (without blanks) work as expected. - Now clearing an event's Title, ShortText and Description if there is no ShortEventDescriptor or ExtendedEventDescriptor, respectively (thanks to Boguslaw Juza for reporting that events without an ExtendedEventDescriptor may get duplicate information in their ShortText through the EPG bugfixes in case they are received again). - Fixed handling video directory updates in case an other process has touched the .update file after the last NeedsUpdate() check (thanks to Petri Hintukainen). - Fixed handling language codes and descriptions of recorded audio tracks on channels with multiple tracks where not all of them appear in the event data (reported by Boguslaw Juza).
