Other changes

• Windows XP is no longer officially supported.
• Changed all color values to be in the range 0-1, rather than 0-255. This affects the following functions:
  • love.graphics.setColor, love.graphics.getColor, love.graphics.setBackgroundColor, and love.graphics.getBackgroundColor.
  • SpriteBatch:setColor and SpriteBatch:getColor.
  • ParticleSystem:setColors and ParticleSystem:getColors.
  • love.graphics.clear.
  • love.graphics.newMesh, Mesh:setVertex, and Mesh:getVertex.
  • The colored text variants of love.graphics.print, love.graphics.printf, love.graphics.newText, Text:set, Text:setf, Text:add, and Text:addf.
  • Shader:sendColor.
  • love.graphics.points.
  • ImageData:setPixel, ImageData:getPixel, and ImageData:mapPixel.
  • love.math.gammaToLinear and love.math.linearToGamma.

• Changed high-dpi functionality to require much less code (often none at all) for graphics to appear at the correct sizes and positions.
• Changed love.graphics.print and friends to ignore carriage returns.
• Changed the 'multiply' BlendMode to error if not used with the 'premultiplied' BlendAlphaMode, since the formula only works with that anyway.
• Changed some love.graphics, love.window, and love.event APIs to cause an error if a Canvas is active.
• Changed stenciling functionality with a Canvas active to require stencil=true (or a custom stencil-formatted Canvas) to be set in love.graphics.setCanvas.
• Changed Mesh:setDrawRange to take 'start' and 'count' parameters instead of 'min' and 'max'.
• Changed the 'vsync' field of love.window.setMode and t.window in love.conf. It's now an integer with 0 disabling vsync.
• Changed Channel and love.event.push table serialization to accept non-flat tables and detect cycles, cycles now cause an error rather than a stack overflow.
• Changed Sources to either be playing or not playing, rather than playing, paused, or stopped. Source:stop now pauses and rewinds the Source.
• Changed love.audio.pause() to return a list of Sources that have been paused by that call.
• Changed Source seeking behaviour, all kinds of Sources now behave similarly when seeking past the boundaries.
• Changed love.timer.step to return the calculated delta time.
• Changed love.run and love.errorhandler to return a function for their main loop, which gets called until love quits.
• Changed enet to no longer set the 'enet' global.
• Changed love.keyboard.isDown and love.keyboard.isScancodeDown to error if an invalid enum value is given.

• Updated and improved command line argument handling.
• Updated the boot sequence to show an error instead of the no-game screen, if a nonexistant folder is passed in as the source game directory.
• Updated 'love.exe --version' on Windows to print to the parent console.
• Updated Android print rerouting and JIT compilation disabling to apply inside threads.
• Updated invalid enum value error messages to show a list of the valid enum values.
• Updated Source:seek to work if the Source isn't playing.
• Updated love.math.random to have improved numeric distribution.
• Updated love.graphics to support Core Profile OpenGL 3.3+ when available.
• Updated Shaders to always expose derivative functions (dFdx, dFdy, fwidth) when available in OpenGL ES.
• Updated Shaders to allow using VERTEX and PIXEL as variable names in shader code.
• Updated love.graphics.circle, love.graphics.ellipse, love.graphics.arc, and love.graphics.rectangle to take transformation scale into account when determining the number of segments to use.
• Updated the error message when bad values are given to love.graphics.line.
• Updated Font glyph generation to improve antialiasing.
• Updated Canvas:newImageData to return an ImageData with a format that matches the Canvas' as closely as possible.
• Updated love.graphics.newImage to treat file names ending with "@2x", "@3x", etc. as a pixel density scale factor if none is explicitly supplied.
• Updated the maximum love.graphics transformation/state stack depth from 64 to 128.
• Updated the default error handler to allow copying the error to the clipboard when the user decides to do so.
• Updated love.filesystem.setRequirePath to support multiple template '?' characters in each path.
• Updated luasocket to version 3.0rc1.
• Updated love.joystick.loadGamepadMappings so it doesn't error when given an empty string.
• Updated love.joystick.setGamepadMapping to use the controller's name for the new mapping when possible.

Performance Improvements

• Improved performance when drawing Textures, shapes, lines, and points by automatically batching their draw calls together when possible.
• Improved performance of Shader:send when the Shader is not active.
• Improved performance of love.math.randomNormal when LuaJIT's JIT compiler is enabled.

• Fixed the default reference angle for WeldJoint, PrismaticJoint, and RevoluteJoint.
• Fixed Fixture:getShape to reuse the existing internal Fixture-owned Shape.
• Fixed MouseJoint:setFrequency to error instead of crashing if a frequency of 0 is set.
• Fixed love.system.setClipboardText and love.system.getClipboardText to error instead of crashing, when a window hasn't been created.
• Fixed Joystick:getGamepadMapping to work with xinput controllers.
• Fixed love.joystick.setGamepadMapping's replacement code.
• Fixed baseline calculation when rendering text.
• Fixed Shader:send and Shader:sendColor ignoring the last argument for an array.

• Fixed love.window.isMaximized.
• Fixed Video playback to work with a wider range of Ogg Theora files.
