SDL Sopwith v2.5.0

• There is still no editor for making custom levels, but a Python library has been added for programmatically generating levels. An example level has been included, the first custom level!
• Objects in custom levels can now be arbitrarily mirrored and rotated.
• The numeric keypad enter key can now be used to switch into fullscreen mode, and also when entering a hostname (thanks TechKnight).
• A long-standing bug was fixed where the computer planes would try to take off by flying straight up and then immediately stalling.
• The score is no longer reset between levels (this was a bug).
• At end of level, the remaining planes now "tick down" properly.
• A bug was fixed where the app icon was shown as a black silhouette.
• The manual page now documents the dashboard layout.
• The score will no longer be drawn over the medals for very large values.

SDL Sopwith v2.4.0

• There is now an emscripten (web) version, available on the website.
  (Thanks go to @midzer, who previously did an Emscripten port and whose
  work I built on to put the build script together).
• It is now possible to make and load custom levels (there is no proper
  level editor available yet though).
• There are now a number of alternative palettes that can be used that
  simulate different CGA palettes and old monitors (thanks techknight).
• There are now hotkeys to end or restart the current game (thanks
  techknight).
• There is now a -p command line option to specify TCP port number.
• The Windows package now includes a copy of the Unix manual pages.
• Sound is now oversampled to reduce sound aliasing (thanks @kmill).
• Starting level is now synchronized between players at multiplayer start.
• A bug was fixed with the keybindings menu not working (thanks ranguli,
  NY00123)
• A missing include was added to fix build on Alpine Linux (thanks John
  Gebbie)
• An input bug was fixed where a backspace would leave some visual
  corruption, and the cursor now blinks.
• A bug was fixed where the same medal could be awarded twice.
• Timing of music on the title screen was fixed (thanks @NY00123).

SDL Sopwith v2.3.0

• Sound on Windows was fixed.
• Medals are no longer cleared after a crash. Players now keep their medals until the end of the level, like their score.
• The purple heart medal is now only awarded to players injured in combat. Surviving a bird strike or crashing into an ox doesn't cut it.
• Out of tree builds were fixed (thanks Will Thompson)
• The close button now quits the game (thanks Will Thompson)
• The help screen is no longer shown when aborting the game.

SDL Sopwith v2.2.0

• Multiplayer support was added for the Windows version, at long last.
• Help text is now shown for new players. This is shown on game start in
  novice mode, but won't be shown again after a successful flight. The help
  text will also appear in other single player modes, but only if it looks
  like you're really struggling to get the plane off the ground.
• It's no longer possible to flip the plane upside down while sitting
  motionless on the runway (a bug since the original DOS versions).
• It's no longer possible to get wounded on the ground. If a plane shoots
  another on the ground, that's a successful raid. This fixes a bug where
  a wounded plane on the runway would still be damaged after takeoff.
• The game no longer freezes up in multiplayer mode if the other player
  quits. When establishing a connection, a helpful message is shown about how
  to abort.
• An extra help doc was added for macOS users.
• If the game quits with an error, a friendly dialog box now shows the error.
• Some minor manpage fixes: the deleted missiles mode flag is no longer
  mentioned, and the spacing appears correct on OpenBSD man(1).
• Lots more internal cleanups making good progress towards eventually adding
  support for custom levels.

SDL Sopwith v2.1.1

• An embarrassing bug was fixed where you could win by bombing your own
  buildings.
• The ox "splat" screen now shows correctly if you are shot down and crash
  into an ox.

sdl-sopwith-2.1.0

Bug fixes and changes in this version:

• libm is included as a dependency when needed (thanks slicer69).
• No error is printed if the config file doesn't exist (thanks Kenneth
  Pronovici).
• The screen is now redrawn properly when in menus and the window is uncovered
  or resized (thanks Kenneth Pronovici).
• Some potential crashes were fixed when near the edges of the map.
• Some of the code has been refactored to centralize how levels are defined. In
  the future this will help to support custom levels.

Documentation changes:

• Build instructions were clarified (thanks Kenneth Pronovici).
• Better documentation of novice mode was added to the manpage (thanks Kenneth
  Pronovici).
• References to the -p argument were removed from the manpage and the help text
  (thanks Kenneth Pronovici).

SDL Sopwith v2.0.0

Changes in this version:

• Sound has been reenabled. Sound output is now passed through a bandpass
  filter intended to make it sound like a real PC speaker, and also plays
  back at a much quieter volume, to be less startling to new players.
• Medals are now awarded to reward players (thanks creichen). The Unix
  manpage includes some details about the medals and how to attain them.
• There is now a configuration screen for setting key bindings, which are
  stored in the same configuration file as other settings.
• Thanks to SDL2's renderer API, the game now scales up to arbitrary window
  sizes and resolutions, and isn't limited to just 320x200 or 640x400.
• Network performance has been improved significantly.
• The Unix manpage has been significantly improved and expanded. A separate
  manpage was added for the configuration file.
• Sopwith now runs on macOS, and Mac .dmg packages are generated.
• Also now builds and runs cleanly on Haiku.
• The Windows .exe now has metadata and an icon.
• The missiles feature was changed to a hidden setting since it's not very
  fun and doesn't really fit the game's theme.
• The networking option to use a "TCP loop" has now been merged with the
  normal "connect" option, for simplicity. The target server may be a real
  server or a TCP loop server, and the clients will autodiscover.

Bug fixes:

• Movement precision within the game was made significantly more precise.
  This fixes a long-standing issue where fractional movement values were
  just being discarded, instead of being included in calculations as they
  should have been.
• Fix computer planes not shooting when tailing the player's plane (creichen).
• Fix planes crashing into their own bullets (creichen).
• Fix players able to turn quickly when wounded and using the autopilot.
• Damaged ground no longer remains on the title screen after the game ends.
• Network games no longer desync when only one player uses harry keys mode.
• Big oil tank explosions now match the magnitude of the old explosions from
  Sopwith 1 and Sopwith 2. The command line option to disable them has been
  replaced with a configuration variable.
• A bug was fixed where it was possible to stop the plane in midair when
  playing the game in novice mode (thanks Alaux).

Restructuring:

• Code has been ported to SDL2.
• Rewritten graphics code
• Major internal restructuring: removal of obsolete code, removal of
  some global variables
• Sopwith configuration file is no longer ~/.sopwithrc on *nix systems, but
  can now be found at ~/.local/share/SDL\ Sopwith/sopwith.cfg
