=== 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 the matrix variant of [[Shader:send]] to interpret the matrix as row-major by default, instead of column-major.
* Changed the variant of [[Canvas:newImageData]] which accepts x/y/width/height to also require slice and mipmap index parameters, which are used when the Canvas isn't a 2D [[TextureType|type]] or has mipmaps.
* 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 variant of [[love.image.newImageData]] which takes dimension arguments to take an optional [[PixelFormat]] argument as well.
* 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 [[Source]]s 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|love.audio.pause()]] to return a list of [[Source]]s 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 [[SpriteBatch]]es to automatically grow their buffer when they run out of space.
* Updated [[Shader]]s to always expose derivative functions (dFdx, dFdy, fwidth) when available in OpenGL ES.
* Updated [[Shader]]s 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 [[love.graphics.push|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 [[socket|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.

* Fixed [[ParticleSystem:setParticleLifetime]] to error if a negative value is given.
