+  * Changed love.graphics.print and friends to ignore carriage returns.
+  * Changed the 'multiply' blend mode to error if not used with the 'premultiplied' blend alpha mode, 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 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.

+  * Fixed VaryingTexCoords and love_ScreenSize in shaders to be 'highp' in OpenGL ES, when supported.
+  * Fixed ParticleSystem:setParticleLifetime to error if a negative value is given.
   * Fixed Shader:send and Shader:sendColor ignoring the last argument for an array.
   * Fixed a crash when love.graphics.pop is called after a love.window.setMode while the transformation stack was not empty.
+  * Fixed love.window.isMaximized.
+  * Fixed video playback to work with a wider range of Ogg Theora files.
