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 default skin "LCARS" displays the signal strengths and qualities of
all devices in its main menu. For devices that have an stb0899 frontend chip
(like the TT-budget S2-3200) retrieving this information from the driver is
rather slow, which results in a sluggish response to user input in the main
menu. To speed this up you may want to apply the patches from

   ftp://ftp.tvdr.de/vdr/Developer/Driver-Patches

to the LinuxDVB driver source.

From the HISTORY file:
- Fixed sorting recordings in the top level video directory.
- Fixed handling control characters in SI data in case of UTF-8 encoded strings
   (thanks to Mehdi Karamnejad for reporting a problem with garbled UTF-8 EPG data
   and helping to debug it).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- When checking whether a video directory is empty, file names that start with a
   dot ('.') are now ignored and will be implicitly removed if the directory contains
   no other files. This fixes the leftover ".sort" files that were introduced in
   version 1.7.29.
- Added IsUpdate() to the EPG handler interface (thanks to Jörg Wendel).
- Fixed detecting transfer mode on full featured DVB cards (thanks to Stefan Huelswitt
   for reporting a problem with updating CA descriptors in such cases).
- Fixed a race condition when zapping in transfer mode (reported by Reinhard Nissl).
   This involves a slight change in the semantics of the cReceiver::Activate() function,
   which is now called with 'false' after the receiver has been detached from the
   device.
- The new function cDevice::ReadFilter() can be used by devices to implement their
   own way of retrieving section filter data (thanks to Deti Fliegl).
- The new function cDevice::HasInternalCam() can be implemented by devices that
   provide encrypted channels in an already decrypted form, without requiring explicit
   handling of a CAM (thanks to Tobias Grimm).
- VDR can now be built according to the FHS ("File system Hierarchy Standard") by
   activating the line
   #USEFHS = 1
   in a copy of the file Make.config.template (thanks to Dennis Bendlin, as well as
   Christopher Reimer and Udo Richter for contributing to the patch).
- By default (without FHS support) the config directory is now set to the value
   given in the -v option if only -v and no -c is given.
- Fixed a long delay at the end when replaying a recording that has stopped recording
   less than an hour ago (typically time shift mode or a freshly edited recording).
- Fixed getting the file size and number of frames of ongoing recordings (only the
   timestamp of the recording's directory was checked, while it should have been that
   of the index file).
- Fixed sluggish response when manipulating editing marks while a cutting thread
   is running (reported by Torsten Lang).
- The new setup options "OSD/Color key [0123]" can be used to adjust the sequence
   of the color buttons displayed in the menus to that of the color keys on your
   remote control (based on a patch from Oliver Schinagl).
   Authors of plugins that implement skins may want to adapt their SetButtons()
   function in order to make use of this new feature. See, for instance, the function
   cSkinClassicDisplayMenu::SetButtons() in skinclassic.c for details.
