HISTORY

@@ -8953,3 +8953,9 @@ Video Disk Recorder Revision History
an "SVDRP default host" has been set for normal timer recordings.
- cOsdMenu::Display() now checks whether the OSD size has changed and if so calls
SetDisplayMenu().
- The SVDRP commands that deal with recordings (DELR, EDIT, LSTR, MOVR, and PLAY)
now use a unique id for each recording, which remains valid as long as this
instance of VDR is running. This means that recordings are no longer continuously
numbered from 1 to N in LSTR. There may be gaps in the sequence, in case recordings
have been deleted, and they are not necessarily listed in numeric order.
Thanks to Sergey Chernyavskiy.
