[ Markus Wanner ]
* Upload to unstable.
* Adjust B-D to allow building on kfreebsd-*. Closes: #724686.
* Add a lintian-overrides on autotools; we use cmake.
* Upstream corrected the fgfs manpage. Closes: #556362.
* Drop unnecessary man page for gl-info. Closes: #698308.
* Drop README.Linux: it's outdated to the point of uselessness.
  Closes: #574173.
* Add an upper limit of libsimgear-dev versions that flightgear can be
  built with. Closes: #738436.
* Drop the libsvn-dev dependency, neither flightgear nor simgear depend
  on libsvn, anymore. Closes: #682947.
* List icons in debian/install rather than copying around from rules.
* Update menu entry for flightgear, add one for fgcom; add .xpm icons.
  Closes: #713924.
* flightgear.desktop: add German translation
* Bump Standards-Version to 3.9.5; no changes needed.

[ Rebecca Palmer ]
* New upstream release.
* Install the icons (based on code by Saikrishna Arcot).  (Not a
  complete fix for LP908153 as it only sets the menu/Dash icon, not the
  running window's icon, but better than nothing).
* Disable screensaver while running. Closes: LP#793599. Add required
  libdbus-1-dev dependency.
* Remove outdated README.Debian.
* Terrasync now works after just ticking the box. Closes: #252899.
* Always set Terrasync directory.
