The information on this page may not be accurate or up to date due to the information pertaining to a version that is currently in development.

The codename for LÖVE 0.10.0 is not yet announced. It is currently not released.

Changes from 0.9.2

Additions

• Added an iOS port.
• Added an Android port.
• Added the flag t.accelerometerjoystick to love.conf. Disables accelerometer-as-joystick functionality on mobile devices when false.
• Added the flag t.gammacorrect to love.conf (replaces t.window.srgb.) Enabling it globally enables gamma-correct rendering, when supported.
• Added love.touch module. Note that it has important differences from the touch implementation in the LÖVE 0.9.2 Android and iOS ports.
  • Added love.touch.getPosition
  • Added love.touch.getTouches
• Added love.touchpressed, love.touchreleased, and love.touchmoved.
• Added love.system.vibrate.
• Added love.filesystem.setRequirePath and love.filesystem.getRequirePath.
• Added an optional program exit status number argument to love.event.quit.
• Added love.filedropped and love.directorydropped event callback functions.
• Added love.lowmemory event callback function, called when the app is running out of memory on mobile operating systems.
• Added love.textedited event callback function, called when the user is compositing text (e.g. via an IME.)
• Added love.wheelmoved event callback function (replaces "wu" and "wd" constants for love.mousepressed.)
• Added love.mouse.hasCursor.
• Added a boolean argument to love.mousepressed and love.mousereleased indicating whether the button event originated from a touch press.
• Added optional x/y/width/height arguments to love.keyboard.setTextInput. They tell the system where text will show up so on-screen keyboards can avoid that area.
• Added Source:getType (replaces Source:isStatic.)
• Added Source:getDuration and Decoder:getDuration.
• Added an optional string argument containing raw pixel data to the width/height variant of love.image.newImageData.
• Added love.graphics.ellipse.
• Added rounded-rectangle support to love.graphics.rectangle.
• Added love.graphics.points (replaces love.graphics.point.)
• Added love.graphics.intersectScissor.
• Added an optional boolean argument to love.graphics.setBlendMode which indicates whether the blend mode should multiply alpha with rgb for the source color. It is true by default.
• Added a new built-in shader variable: "mat3 NormalMatrix".
• Added love.graphics.getSupported (replaces love.graphics.isSupported.)
• Added love.graphics.getSystemLimits (replaces love.graphics.getSystemLimit.)
• Added love.graphics.stencil, love.graphics.setStencilTest, and love.graphics.getStencilTest. (replaces love.graphics.setStencil.)
• Added love.graphics.isActive.
• Added color arguments to love.graphics.clear. It no longer always uses the background color value.
• Added love.graphics.discard.
• Added love.graphics.isGammaCorrect.
• Added the ability to specify custom mipmaps when creating an image, via love.graphics.newImage(filename, {mipmaps={mip1, mip2, ...}}).
• Added optional x/y/width/height arguments to Image:refresh and Canvas:newImageData.
• Added Image:getFlags.
• Added one- and two-channel Canvas formats: r8, rg8, r16f, rg16f, r32f, and rg32f.
• Added support for different formats in each Canvas when using multi-canvas rendering. Added the "multicanvasformats" GraphicsFeature constant.
• Added support for OpenGL ES 2 and 3.
• Added support for loading ETC1, ETC2, EAC, and PVRTC1 compressed textures on systems that support them.
• Added custom vertex attribute support for Meshes via new variants of love.graphics.newMesh.
• Added Mesh:setVertexAttribute and Mesh:getVertexAttribute, Mesh:getVertexFormat, and Mesh:flush.
• Added Mesh:setAttributeEnabled and Mesh:isAttributeEnabled.
• Added Mesh:attachAttribute.
• Added Shader:sendColor.
• Added new shader functions: gammaCorrectColor, gammaToLinear, and linearToGamma. The functions also have 'precise' and 'fast' variants.
• Added Text objects and love.graphics.newText.
• Added per-character color support to love.graphics.print, love.graphics.printf, and Text objects.
• Added BMFont bitmap font file support to love.graphics.newFont and love.font.
• Added kerning support for TrueType/OpenType and BMFont Fonts.

• Added love.window.maximize.
• Added love.window.close.
• Added love.window.requestAttention.
• Added BezierCurve:renderSegment and BezierCurve:removeControlPoint.
• Added BezierCurve:getSegment.
• Added love.math.compress and love.math.decompress.
• Added Channel:performAtomic.

Changed APIs

• Changed love.mousepressed, love.mousereleased, and love.mouse.isDown to use button numbers instead of named button constants.
• Changed love.keypressed to be love.keypressed(key, scancode, isrepeat).
• Changed love.keyreleased to be love.keyreleased(key, scancode).
• Changed Font:getWrap's second return value to be a table containing the text split into lines.
• Changed love.graphics.newImage's optional second argument to be a table of flags (flags are "mipmaps" and "linear".)
• Changed the arguments for the standard variants of love.graphics.newMesh. They're now love.graphics.newMesh(vertices [, drawmode, usage]) and love.graphics.newMesh(vertexcount [, drawmode, usage]).
• Changed ImageData:encode to return a FileData object. ImageData:encode's first parameter is now the format to encode to, and the second parameter is an optional filename to write to.

Renamed APIs
