- 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).
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
