- Fixed checking compatibility mode for old subtitles plugin (thanks to Marco
  Schlüßler).
- Updated the French OSD texts (thanks to Michael Nival).
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- The "Play" key now starts replay of the selected recording in the Recordings
  menu (thanks to Ville Skyttä);
- Improved shutdown handling (thanks to Udo Richter).
- Housekeeping now waits for a while after a replay has ended (thanks to Udo Richter).
- Added more special characters to the list of allowed characters when entering
  strings (thanks to Thomas Günther).
- Added Ukrainian language texts (thanks to Yarema Aka Knedlyk).
- Added a workaround for recovering from wrongfully interpreted "pre 1.3.19 PS1 packets".
- Fixed a possible blocking in replay when subtitles are active.
- Fixed displaying subtitles in live mode.
- Fixed handling CONFDIR (thanks to Rolf Ahrenberg).
- Added some missing 'const' keywords (thanks to Sascha Volkenandt).
- The 'Allowed' parameter in cMenuEditStrItem() is now NULL by default, which results
  in using tr(FileNameChars) (suggested by Thomas Günther).
- Added a missing '.' to the date returned by DayDateTime() (thanks to Lauri Nurmi).
- Improved the 'i18n' target in the Makefile to avoid unnecessary work (thanks to
  Stefan Huelswitt). The 'newplugin' and 'i18n-to-gettext.pl' scripts have been
  changed accordingly. Plugin authors may want to adjust the 'i18n' target
  of their Makefiles.
- Fixed a crash if no fonts are found (thanks to Mario Ivankovits and Clemens
  Kirchgatterer).
- Fixed decoding filename characters in case there are not two hex digits after
  the '#' (reported by Helmut Auer).

- Implemented handling DVB subtitles (thanks to Marco Schlüßler, and also to
  Pekka Virtanen for writing the subtitle plugin, which helped in implementing
  subtitle handling in VDR).
- The new remote control key "Subtitles" can be used to bring up the list
  of available subtitles.
- The new setup option "DVB/Subtitle languages" can be used to define the
  preferred languages for subtitles.
- Fixed selecting the audio track when pressing Ok in the Audio menu (thanks
  to Marco Schlüßler).
- Implemented display of DVB subtitles in live viewing mode.
- Implemented subtitle track selection.
- Implemented bitmap color reduction and shrinking to display subtitles even
  on devices that can't display the necessary number of colors.
- Added compatibility mode for playback of recordings made with the subtitles
  plugin (with some help from Rolf Ahrenberg).
- The new setup option "DVB/Subtitle offset" can be used to shift the location
  of the subtitles in the vertical direction.
- The new setup options "DVB/Subtitle foreground/background transparency"
  define an additional level of transparency for the foreground and background
  color of subtitles.
- Existing recordings made with the subtitle plugin can be given an 'X' record
  in their info.vdr file, so that subtitles can be automatically selected upon
  replay, according to the preferred language setup, as in
  X 3 03 ger deutsch
  (see vdr.5). Note that these entries need to be added in the proper sequence,
  so that they correspond with the actual track languages in the recording.
- Now generating translation files without line numbers to avoid unnecessarily
  large diffs. Plugin authors may want to replace the -F option with
  --no-location in the xgettext and msgmerge calls in their Makefiles.
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Added a missing Channels.SetModified(true) call when deleting or moving a
  channel in the Channels menu (reported by Halim Sahin).
- Fixed a missing '-' at the next to last line of SVDRP help texts (reported by
  Denis Knauf).
- Added a missing SetVolumeDevice() call in cDevice::SetPrimaryDevice() (reported
  by Reinhard Nissl).
- Fixed a crash when pressing Left while at the first character of a cMenuEditStrItem
  (thanks to Christian Wieninger).
- Only creating a new cDvbOsdProvider in cDvbDevice::MakePrimaryDevice() if 'On'
  is true (i.e. this device is being made the primary device).
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Fixed handling reallocated memory in cCharSetConv::Convert() (reported by Udo
  Richter).
- Fixed a new[]/delete mismatch in cMenuEditStrItem::LeaveEditMode() (thanks to
  Udo Richter).
- Implemented sending all frames to devices that can handle them in fast forward
  trick speeds (thanks to Timo Eskola).
- Updated the Hungarian language texts (thanks to Thomas Günther).
- Fixed description of DeviceSetAvailableTrack() and cReceiver(), and added an
  example ~cMyReceiver() in PLUGINS.html (thanks to Marco Schlüßler).
- Improved the description of where logging goes in the INSTALL file (thanks to
  Elias Luttinen).
- Added a note about how to initiate internationalization support to the
  README.i18n file. The Makefile generated by the 'newplugin' script now has the
  'i18n' target automatically create an initial 'po/pluginname.pot' file.
  Plugin authors may want to add the '$(I18Npot)' dependency to the 'i18n'
  target in their Makefiles, as in
  i18n: $(I18Npot) $(I18Nmo)
  (based on a suggestion by Torsten Kunkel).
- Removed a duplicate ',' from the ca_ES.po file (thanks to Thomas Günther).
- Added the 'ß' character to the "allowed characters" in the de_DE.po file
  (suggested by Thomas Günther).
- Made the default copy ctor of cRecording private (thanks to Markus Hahn).
  Same for the assign operator.
- Added cRecording::Undelete() (based on a patch from Markus Hahn).
- Added cDevice::CloseFilter() to allow a device to have complete control over
  both opening and closing section filters (thanks to Rolf Ahrenberg).
- Some fixes to PLUGINS.html (thanks to Rolf Ahrenberg).

- Fixed handling locale directories with a large number of entries (thanks to
  Anssi Hannula).
- Updated Turkish language texts (thanks to Oktay Yolgeçen).
- Fixed stripping the context in I18nTranslate() (reported by Christian
  Wieninger).
- Fixed detecting whether a particular locale is actually supported.
- Added a note about LANG having to be set to a valid locale in INSTALL
  (suggested by Matthias Fechner).
- Fixed some compiler warnings with gcc-4.2.0 (thanks to Matthias Schwarzott).
- Fixed setting the locale file name in i18n-to-gettext.pl (thanks to Matthias
  Schwarzott).
- Changed the default for LOCDIR in Makefile and Make.config.template to
  "./locale", so that internationalization works by default when running VDR
  from within its source directory (suggested by Anssi Hannula).
- Added the new i18n macro trVDR(), which can be used by plugins to mark
  texts they want to reuse from VDR's core translations (suggested by Matthias
  Becker).
- VDR now uses the default configuration directory as defined in the CONFDIR
  varable in the Makefile (thanks to Thomas Schmidt).
- The SVDRP command LSTC can now list the channels with group separators if the
  option ':groups' is given (thanks to Andreas Mair).
- Added a missing error report to cCuttingThread::Action() (thanks to Udo
  Richter).
- There can now be more than one OSD at the same time. At any given time,
  however, only one of them can be active (and thus visible). This is to
  allow displaying things like subtitles in an easy way. A cOsd therefore
  now has a "Level", and only the OSD with the smallest level will be
  displayed. The level 0 OSD is special, and there can only be one with
  this level. If there is more than one OSD with a particular level, only
  the one that was created first will be displayed.
  Plugins that provide an OSD need to adjust their cOsdProvider::CreateOsd()
  function to hand through the Level.
- Fixed checking for ttDolbyLast in cDevice::SetCurrentAudioTrack() (thanks
  to Marco Schlüßler).

- Added missing install-i18n to the install target in the Makefile (reported
  by Joachim Wilke).
- Fixed a faulty comment in Make.config.template (reported by Marco Schlüßler).
- Improved i18n-to-gettext.pl (thanks to Matthias Schwarzott).
- Moved the "all" target in plugin Makefiles before the "Implicit rules",
  so that a plain "make" will compile everything (suggested by Matthias
  Schwarzott). The "newplugin" script has been changed accordingly.
  Plugin authors may want to change their Makefiles, too.
- Added DESTDIR and PREFIX handling to the Makefile (thanks to Matthias
  Schwarzott).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Added internationalization to the "skincurses" plugin (thanks to Rolf
  Ahrenberg).
- Checking the string for NULL in I18nTranslate().
- Updated the French OSD texts (thanks to Bruno Roussel).
- Some optimizations in cDvbDevice::SetChannelDevice() (thanks to Tobias Bratfisch).
- Optimized cMenuEditChrItem::Set() (thanks to Tobias Bratfisch).
- Optimized cNitFilter::Process() (thanks to Tobias Bratfisch).
- Reduced the number of time(NULL) calls in vdr.c's main loop to a single call
  (thanks to Tobias Bratfisch).
- Changed cBitmap::DrawText() to always draw the background unless ColorBg
  is clrTransparent (thanks to Christoph Haubrich).
- The "Setup/OSD/Language" menu now only shows those languages that actually
  have a locale (suggested by Anssi Hannula).
- Now using setenv() instead of setlocale() to set the language for gettext()
  (suggested by Anssi Hannula; thanks also to Ludwig Nussel for a hint on using
  _nl_msg_cat_cntr).
- When scanning the locale directory, VDR now explicitly looks for a file named
  vdr.mo. Text files for plugins are now named "vdr-name.mo", when "name" is the
  name of the plugin. The "newplugin" script has been changed accordingly, and
  plugin authors should change their Makefiles, too.

- All logging now goes to LOG_ERR, because some systems split error, info and
  debug messages into separate files, which repeatedly caused extra efforts to
  find out when incomplete log excerpts were attached to problem reports in
  the past.
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Fixed a problem with characters >0x7F in the modified version of skipspace()
  (thanks to Marco Schlüßler).
- Fixed a bug I introduced when simplifying the original patch for detecting
  Premiere NVOD channel links (crash reported by Malte Schröder).
- Internationalization is now done with 'gettext' (following a suggestion by
  Lucian Muresan). Plugin authors may want to use the Perl script
  'i18n-to-gettext.pl' to convert their internationalized texts to the gettext
  format (see the instructions inside that script file). The function
  cPlugin::RegisterI18n() is still present for compatibility, but doesn't
  have any more functionality. So plugins that don't convert their texts to
  the gettext format will only present English texts.
  See PLUGINS.html, section "Internationalization", for instructions on how
  to make strings in arrays translatable.
  See README.i18n for information on how to create new or maintain existing
  translations.
- The three letter language codes and their aliases are stored in i18n.c, and
  each translation file only contains one of them to link that language name
  to the code.
- The 'newplugin' script has been extended to generate the Makefile section
  for i18n support.
- The parameter OSDLanguage in 'setup.conf' is now a string and holds the locale
  code of the selected OSD language (e.g. en_US). If Setup.OSDLanguage is not
  set to a particular locale that is found in VDR's locale directory, the
  locale as defined in the system environment is used by default.
- The list of tracks given in cStatus::SetAudioTrack() is now NULL terminated,
  so that plugins can actually use all the strings in the list, not just the
  one pointed to by Index (thanks to Alexander Rieger).
- Fixed handling kLeft in the calls to cStatus::MsgOsdTextItem() (thanks to
  Alexander Rieger).
- Added the "...or (at your option) any later version" phrase to the license
  information of all plugins, and also the 'newplugin' script (suggested by
  Ville Skyttä). Plugin authors may want to consider doing the same.
- Fixed the link to the GPL2 at http://www.gnu.org in vdr.c (thanks to Ville
  Skyttä).
- cBitmap::SetXpm() now checks whether the given Xpm pointer is not NULL, to
  avoid a crash with files that only contain "/* XPM */" (suggested by Andreas
  Mair).
- Added a debug error message to cReceiver::~cReceiver() in case it is still
  attached to a device (thanks to Reinhard Nissl).

- Increased APIVERSION (forgot to do that in 1.5.2 and 1.5.3).
- Fixed a crash in i18n character set conversion (thanks to Alexander Riedel,
  Jose Alberto Reguero and Christian Wieninger for patches that cured part of
  the problem).
- Adjusted the 'skincurses' plugin to UTF-8 handling.
- Using nl_langinfo(CODESET) to determine the local codeset to use (thanks to
  Thomas Günther). The codeset names in 'libsi/si.c' have been changed to the
  canonical spelling with '-' (thanks to Ludwig Nussel for pointing this out).
- Modified handling invalid characters in VFAT mode.
- Replaced strn0cpy() with Utf8Strn0Cpy() where necessary.
- Now using 'fontconfig' to determine which fonts to use (thanks to Anssi Hannula
  for code and hints on how to do this).
- If no fonts are installed, VDR now uses a dummy font that doesn't actually draw
  any text, and logs an error message.
- The new function cFont::CreateFont() can be used by plugins to create and use
  fonts of their own, independent of VDR's standard fonts.
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Changed the parameter "OSD font" to "Default font" in "Setup/OSD" (suggested
  by Rolf Ahrenberg).
- Fixed handling detached processes in SystemExec() (thanks to Udo Richter).
- The info.vdr file now also stores the name of the channel, and the new function
  cRecordingInfo::ChannelName() returns this information if available (based on
  a patch from Alexander Hans).
- The new function cOsd::SetOsdPosition() can be used to dynamically change the
  position and size of the OSD (based on a request from Christoph Haubrich).
  Plugins that implement skins should no longer use Setup.OSDWidth etc. directly,
  but should rather use cOsd::OsdWidth() etc. instead.
  Currently a change to the OSD position will only apply to newly opened OSDs.

- Fixed some spelling errors in 'newplugin' (thanks to Ville Skyttä).
- Fixed a busy loop in fast forward if the next video data file is missing
  (thanks to Reinhard Nissl).
- Fixed handling frequencies in NitFilter::Process() (thanks to Anssi Hannula).
- Fixed a race condition with signal handlers at program exit (thanks to Udo
  Richter).
- Non-primary devices in Transfer mode are now also used for recording (thanks
  to Anssi Hannula).
- Fixed handling ChannelUp/Down keys if there is currently a replay running
  (thanks to Marco Schlüßler).
- The new SVDRP command REMO can be used to turn VDR's remote control off and
  on in case other programs need to be controlled (based on patches from Krzysztof
  Parma and Helmut Auer).
- Increased the maximum number of CA system ids to cope with the AlphaCrypt
  CAM's version 3.11 firmware.
- Fixed getting the code setting from the locale (thanks to Matthias Schwarzott).
- Implemented support for Freetype fonts (based on a patch from Alexander Riedel).
  The font names and sizes can be adjusted in the "Setup/OSD" menu.
  Note that VDR now requires freetype fonts to be installed in
  /usr/share/fonts/truetype.
- If the OSD device in use has at least 8bpp bitmap depth and this is also
  used by the current skin, Freetype fonts are displayed "anti-aliased".
  The new setup parameter "OSD/Anti-alias" can be used to turn this off.
- The new function cOsd::SetAntiAliasGranularity() can be used to help the OSD
  in managing the available color palette entries when doing anti-aliasing.
  Skins that use 8bpp bitmaps can call this function with the maximum number
  of colors used, and the maximum number of color combinations. The OSD will
  then evenly split the available palette entries between the various colors
  combinations, so that fonts can be "anti-aliased". By default a total of
  10 colors and 10 combinations is assumed.
- The pixel fonts have been completely removed from the VDR source.
- VDR is now "UTF-8 aware". It handles strings according to the character
  encoding used on the user's system. All internationalization strings and
  incoming SI data are converted to the system encoding.
- Plugins that handle strings need to be aware that on systems with UTF-8
  encoding a "character symbol" may consist of more than a single byte in
  memory. The functions and macros named Utf8...() can be used to handle
  strings without needing to care about the underlying character encoding
  (see tools.h for details).
- Even though the weekdays of repeating timers are presented to the user as UTF-8
  characters in the OSD, the timers.conf file and the SVDRP timer commands still
  use single byte characters ("MTWTFSS") to make sure this information is handled
  correctly between systems with different character encodings.
- Added a missing i18n string for "CAM" in the Turkish OSD texts.
- Improved editing strings that are too long to fit into the editable area.
- Changes to the OSD settings in the "Setup/OSD" menu now immediately take effect
  when the "Ok" key is pressed.

- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Fixed handling user activity for shutdown, which I had messed when adopting Udo's
  original patch (thanks to Udo Richter).
- Added Turkish language texts (thanks to Oktay Yolgeçen).
- Added missing rules for generating iso8859-13 font to Makefile.
- 'libsi' now converts the incoming strings into the system's character set
  according to the DVB standard. The system's character set is determined from
  the LANG environment variable. If no recognizable setting can be found, no
  conversion will take place. Note that currently only the strings received from the
  SI data stream are converted, there have not been any changes regarding displaying
  UTF-8 characters on the OSD, yet - this will follow in one of the next steps.
  With this conversion, it should now be safe to run VDR on a UTF-8 file system,
  because all incoming characters are converted to UTF-8. This will most likely
  result in wrong characters being displayed on the OSD (because there UTF-8 is
  not known, yet), but the file names should be ok (haven't tested this myself,
  though, because I don't do UTF-8 - so please be very careful when testing!).
  There's one piece of bad news here: the German pay-tv broadcaster Premiere
  apparently encodes all EPG strings as ISO8859-1, but fails to correctly mark
  these strings as such. Therefore 'libsi' (following the DVB standard) considers
  the strings to be encoded in the default ISO6937 and converts them to whatever
  the system's character set is. This, of course, results in wrong umlauts.
  On its old transponder, the ProSieben/SAT.1 channels also had their EPG data
  wrongly encoded, but apparently on the new transponder they started broadcasting
  on this month, they got it right.

- Added cDevice::HasCi() so that devices with Common Interface can be avoided
  when tuning to an FTA channel, thus preserving the CAM resources even on budget
  DVB cards (suggested by Petri Helin).
- Fixed i18n characters for the Hungarian texts (thanks to Thomas Günther).
- Now using cPipe instead of popen() in cCommand::Execute() to avoid problems
  with open file handles when starting background commands (thanks to Reinhard
  Nissl).
- Removed 'assert(0)' from cDvbSpuDecoder::setTime() (thanks to Marco Schlüßler).
- Fixed a possible crash when loading an invalid XPM file (thanks to Martin Wache).
- Updated satellite names in 'sources.conf' (thanks to Thilo Wunderlich).
- Adapted 'libsi' to DVB-S2 (thanks to Marco Schlüßler).
- Fixed handling error status in cDvbTuner::GetFrontendStatus() (thanks to
  Reinhard Nissl).
- Shutdown handling has been rewritten (thanks to Udo Richter).
- Plugins can now implement the new function WakeupTime() to request VDR to wake
  up at a particular time (thanks to Udo Richter).
- The HUP signal now forces a restart of VDR (thanks to Udo Richter).
- cThread::EmergencyExit() has been replaced by ShutdownHandler.RequestEmergencyExit().
- Several references to "button" in a remote control context have been changed
  to "key" (based on a report from Marko Mäkelä regarding the "Menu button closes"
  text). The "MenuButtonCloses" parameter in 'setup.conf' has therefore been
  renamed to "MenuKeyCloses", accordingly. This will result in an "unknown config
  parameter: MenuButtonCloses" error message in the log file, so you may want to
  remove that entry from your 'setup.conf' file.
- Simplified the error handling in cDvbTuner::GetFrontendStatus() (based on a
  discussion with Reinhard Nissl).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Increased the maximum number of DVB devices to 8 (thanks to Rolf Ahrenberg).
- The new Setup parameter "Channel entry timeout" can be used to customize the time
  since the last keypress until a numerically entered channel number is considered
  complete, and the channel is switched (suggested by Helmut Auer). Setting this
  parameter to 0 turns off the automatic channel switching, and the user will
  have to confirm the entry by pressing the "Ok" key.

- The CAM handling has been refactored. Instead of a cCiHandler per device there
  is now an abstract cCiAdapter and a cCamSlot. This allows each slot to be
  accessed individually.
- The general 15 seconds workaround time before opening the CAM menu has been
  removed. If the CAM menu doesn't open within a timeout, the enter menu command
  is now sent again.
- If a CAM is reset or pulled and reinserted, it now automatically starts
  decrypting the current channel again.
- The Setup/CAM menu now dynamically refreshes its items and displays whether
  a CAM is present or ready. The 'Reset' function no longer leaves the menu.
- The CAM menu will now be openend when pressing the Ok key on a slot entry.
- The CAM menu now stays within the current menu context and doesn't close and
  reopen the menu every time an option is selected.
- When an encrypted channel is switched to for the first time, VDR now checks
  explicitly whether a CAM can actually decrypt that channel. If there is more
  than one CAM in the system that claims to be able to decrypt the channel,
  they are all tried in turn.
  To make this possible, an encrypted channel needs to be received in Transfer
  Mode when it is switched to for the first time, so that VDR can determine
  whether the TS packets are actually decrypted. Once a channel is known to
  be decrypted by a particular CAM, the next time it is switched to it will
  be shown in normal live viewing mode.
- A cDevice now automatically detaches all cReceiver objects that receive PIDs
  that can't be decrypted with the current CAM. A plugin that attaches a cReceiver
  to a device should therefore watch the receiver's IsAttached() function to
  see if it is still attached to the device.
- The cReceiver constructor no longer takes an 'int Ca' as its first parameter,
  but rather a 'tChannelID ChannelID'. This is necessary for the device to be
  able to determine which CAM a particular channel can be decrypted with. If the
  channel is known to be unencrypted, or a plugin doesn't want to provide the
  channel id for other reasons, an invalid tChannelID() can be given.
- The cThread::Start() function now waits until a previous incarnation of this
  thread has actually stopped. Before this it could happen that a thread's
  Cancel(-1) function was called and immediately after that it was started again,
  but the Start() function still found it to be 'active'.
- The parameter NeedsDetachReceivers in cDevice::GetDevice(const cChannel *Channel, ...)
  has been removed. A call to this function will automatically detach all receivers
  from the device if it returns a non-NULL pointer.
- The cTimeMs class now accepts an initial timeout value in its constructor.
- A CAM is now explicitly instructed to stop decrypting when switching away from
  an encrypted channel.
- If the CAM in use can decrypt several channels at the same time, VDR can
  now make use if this capability. Whether or not a CAM can decrypt more
  than one channel is determined by sending it an initial empty QUERY command
  and testing whether it replies to it.
- Ca values in the range 0...F in channels.conf can still be used to assign a channel
  to a particular device, but this will no longer work with encrypted channels because
  without valid CA ids VDR can't decide which CAM slot to use. However, since VDR now
  automatically determines which CAM can decrypt which channel, setting fixed
  channel/device relations should no longer be necessary.
  IF AN ENCRYPTED CHANNEL CAN'T BE DECRYPTED AND YOU HAVE A CA VALUE IN THE RANGE
  0...F FOR THAT CHANNEL, SET IT TO 0 (FTA) AND TUNE TO THE CHANNEL AGAIN.
