WARNING:
========

This is a *developer* version. Even though *I* use it in my productive
environment, I strongly recommend that you only use it under controlled
conditions and for testing and debugging.

From the HISTORY file:
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Fixed "warning: invalid suffix on literal" with GCC 4.8 and C++11 (thanks to Joerg
  Bornkessel).
- Fixed the link to "svdrpsend (1)" in the vdr.1 man page (thanks to Chris Mayo).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Updated the Romanian OSD texts (thanks to Lucian Muresan).
- Added functionality based on the "jumpplay" patch from Torsten Kunkel and Thomas
  Günther:
  + The new option "Setup/Replay/Pause replay when jumping to a mark" can be used to
    turn off pausing replay when jumping to an editing mark with the '9' key.
  + The new option "Setup/Replay/Skip edited parts" can be used to automatically skip
    the edited parts of a recording during replay, without the need to actually cut
    the recording.
  + The new option "Setup/Replay/Pause replay at last mark" can be used to make replay
    go into Pause mode when it has reached the last "end" mark.
  + The '8' key for testing an edited sequence now also jumps to the next *end*
    mark if "Setup/Replay/Skip edited parts" is active. This allows for testing edits
    in recordings that have actually been cut, as well as recordings that have not
    been cut, in case "Skip edited parts" is enabled.
- Added support for "Satellite Channel Routing" (SCR) according to EN50607, also
  known as "JESS" (thanks to Manfred Völkel and Frank Neumann).
- The keys '1' and '3' can now be used in replay mode to position an editing mark
  in "binary" mode (based on a patch from Rolf Ahrenberg, with modifications by Helmut
  Auer). See MANUAL, section "Editing a Recording".
- The Yellow button in the "Setup/CAM" menu can now be used to put the selected
  CAM into a mode where it remains assigned to a device that is tuned to the current
  channel until the smart card it contains is activated and the CAM thus starts to
  descramble (see MANUAL, section "Setup/CAM" for details).
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Added ARGSDIR to the ONEDIR section of Make.config.template (suggested by Derek
  Kelly).
- Made cRecording::GetResume() public (suggested by Stefan Braun).
- Fixed setting the read index in cDvbPlayer::Goto() in case Still is false.
- The function cDvbPlayer::Goto() now automatically calls Play() if Still is false.
- Added support for LCN (Logical Channel Numbers), which plugins may use to sort
  channels (thanks to Rolf Ahrenberg).
