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.


The main focus of this version is on adding basic support for positioners
to control steerable satellite dishes. Manually controlling the dish position
and storing individual positions will follow later.

The fixes contained in this version will be released in a stable version 2.0.3
later, if there are no problems.


The changes since version 2.0.0:

- Fixed initializing cDevice::keepTracks.
- Fixed an endless loop in cTextWrapper::Set() in case the given Width is smaller than
   one character (reported by Stefan Braun).
- Removed all "modified since version 1.6" markers from PLUGINS.html.
- Added definitions for older DVB API versions, back until 5.0 (based on a patch from
   Udo Richter).
- Changed cThread::SetIOPriority() from "best effort class" to "idle class" in order to
   improve overall performance when an editing process is running (thanks to Jochen
   Dolze).
- Fixed handling '/' and '~' in recording file names in case DirectoryEncoding is
   used (thanks to Lars Hanisch).
- Changed the sign of the satellite position value in cSource to reflect the standard
   of western values being negative. The new member function cSource::Position() can be
   used to retrieve the orbital position of a satellite.
- Fixed multiple occurrences of the same directory in the recordings list in case there
   are directories that only differ in non-alphanumeric characters (was broken by
   "Fixed selecting the last replayed recording in the Recordings menu in case there
   are folders and plain recordings with names that differ only in non-alphanumeric
   characters" in version 1.7.36).
- Fixed displaying the frame number when setting an editing mark (thanks to Thomas
   Günther).
- Fixed no longer generating any editing marks if the edited recording results in just
   one single sequence (reported by Halim Sahin).
- Fixed an error message when parsing SCR values in diseqc.conf.
- Fixed an unexpected RCS version tag in the newplugin script.
- Fixed an endless loop in the DrawEllipse() functions for very small ellipses (reported
   by Stefan Braun).
- Fixed a crash in the LCARS skin's main menu in case there is no current channel
   (reported by Dominique Dumont).
- Added basic support for positioners to control steerable satellite dishes (based on
   a patch from Seppo Ingalsuo and Ales Jurik).
   + Supports GotoN (aka "DiSEqC 1.2") and GotoX (aka "USALS").
   + The new DiSEqC command code 'P' can be used to instruct a positioner to move the
     dish to the required satellite position. When a 'P' code is processed, further
     execution of the remaining DiSEqC sequence (if any) is postponed until the positioner
     has reached the new satellite position.
   + The new special source value of "S360E" can be used in diseqc.conf to indicate that
     an entry using a positioner can move the dish to any requested position within its
     range. Think of it as "full circle".
   + The devices a particular cDiseqc or cScr applies to are now stored directly in each
     cDiseqc or cScr, respectively.
   + A plugin can implement a custom positioner control (see PLUGINS.html, section "Positioners").
   + The new function cSkinDisplayChannel::SetPositioner() can be implemented by skins to
     show the user a progress display when the dish is being moved. The default implementation
     calls SetMessage() with a string indicating the new position the dish is being moved to.
     The LCARS skin shows a progress bar indicating the movement of the dish.
   + The new parameters "Site latitude", "Site longitude", "Positioner speed", and
     "Positioner swing" in the "Setup/LNB" menu can be used to configure the necessary
     values for a steerable dish.
   + The cDvbTuner now has a new status tsPositioning, in which it waits until a steerable
     dish has reached its target position. Parsing SI data is paused until the target
     position has been reached.
- The LCARS skin now shows the source value of the current channel in its channel display.
- Fixed asserting free disk space in the cutter.
- No longer trying to delete old recordings in AssertFreeDiskSpace() if the given
   Priority is less than 1.
- Fixed handling LIRC events in case repeated events are lost.
- Fixed a possible crash when shutting down VDR while subtitles are being displayed
   (reported by Ville Skyttä).
- cDevice::IsPrimaryDevice() now also checks whether the primary device actually has
   a decoder and returns false otherwise. This should improve device allocation on
   systems that are only used as a receiver and don't actually display anything.
- Increased the value of MAXRETRIES to 20 to reduce the probability of disturbances
   in transfer mode.
- All bonded devices (except for the master) now turn off their LNB power completely
   to avoid problems when receiving vertically polarized transponders (suggested by
   Manfred Völkel and Oliver Endriss).
- Reverted the change from version 1.5.7 that made all logging go to LOG_ERR (thanks
   to Christopher Reimer).
- Added Begin/EndSegmentTransfer() to the EPG handler interface (thanks to Jörg Wendel).
- The code for distributing recordings over several video directories is now
   deprecated and disabled by default.
   You can re-enable this feature by removing the comment sign ('//') from the beginning
   of the line
   //#define DEPRECATED_DISTRIBUTED_VIDEODIR // Code enclosed with this macro is ...
   in the file videodir.c. Note, though, that this can only be a temporary workaround.
   This feature will be completely removed in one of the next developer versions.
   Distributing the video directory over several disks was a useful feature in times
   when disks were still relatively small, but it also caused serious problems in case
   one of the disks failed. Nowadays hard disks come in sizes measured in terabytes,
   and tools like "mhddfs" can be used to combine several disks to form one large volume.
   A recommended method for a relatively safe disk setup in a VDR system is to use two
   1TB (or larger) disks and use them as a RAID-1 (mirrored). That way, if one disk
   fails, you can replace it without data loss.

Have fun!

Klaus
