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 Finnish OSD texts (thanks to Rolf Ahrenberg).
- Changed the Green button in the "Edit timer" menu from "Once" to "Single"
  (suggested by Rolf Ahrenberg).
- Fixed some typos in HISTORY and CONTRIBUTORS (thanks to Ville Skyttä).
- The channel name column in the "What's on now/next" menu now adjusts its width
  to display the full short name of each channel (suggested by Dominic Evans).
- Dropped the meanwhile obsolete script 'i18n-to-gettext'.
- Removed the obsolete function cPlugin::RegisterI18n().
- Removed the obsolete typedef tI18nPhrase.
- Adapted menu column widths of 'skincurses' to the wider HD OSD sizes.
- Deactivated definition of __RECORDING_H_DEPRECATED_DIRECT_MEMBER_ACCESS (recording.h)
  and LEGACY_CRECEIVER (receiver.h) to trigger an error for any plugin that still
  uses the respective code. You can reactivate these to quickly make your plugin
  compile again, but beware that these code parts will be removed in one of the next
  versions.
- Made the "overloaded-virtual" warning an error to detect hidden overloaded
  virtual functions (thanks to Anssi Hannula for pointing out -Werror=...).
  Plugin authors may want to change -Woverloaded-virtual to -Werror=overloaded-virtual
  in their Makefiles.
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Improved fast forwarding to the end of a timeshift recording.
- The new function cDevice::DeviceName() returns a string identifying the name of
  the given device.
- When toggling a timer between "Single" and "Repeating", the previous setting is now
  retained in case the user toggles back to the original value.
- When estimating the remaining disk space (in hours), the average data rate of all
  existing recordings is now taken into account. If this value can't be determined,
  the previous value of 25.75 MB/min is taken.
- No longer using GetFont() (which is not thread safe) in the 'osddemo' plugin.
- No longer using GetFont() (which is not thread safe) in cSubtitleRegion::UpdateTextData().
- Fixed a memory leak in cSubtitleRegion::UpdateTextData().
- Moved setting LC_NUMERIC further up to make sure any floating point numbers use a
  decimal point (suggested by Tobias Grimm).
- Added missing channel locking to cEIT.
- Fixed reduced bpp support for DVB subtitles (thanks to Rolf Ahrenberg).
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Reverted some improvements to Make.config.template (thanks to Christian Ruppert).
- Fixed handling IDLEPRIORITY in cDvbDevice::ProvidesChannel() (thanks to Frank
  Schmirler).
