love.graphics.getSupported():
- Added “fullnpot” field, is true everywhere except on some older mobile devices. If false, mipmapping and wrap modes other than “clamp” can’t be used on non-power-of-two sized textures.
- Added “pixelshaderhighp” field, is true everywhere except some older mobile devices. If false, “highp” precision can’t be used in pixel shaders and love will default to “mediump” instead.
love.graphics.getSystemLimits():
- Added “anisotropy” field, gets the maximum amount of anisotropy you can specify in Texture:setFilter. love will clamp anisotropy arguments greater than this value.

Also allow arrays of images/samplers in shaders, although driver support is iffy and you have to index into the array using a compile-time constant (which might exclude loop indexing).

- Removed love.graphics.set/getCanvas, Canvas:renderTo, Canvas:newImageData, love.graphics.clear, love.graphics.discard, and love.graphics.newScreenshot.
- Added love.graphics.beginPass and love.graphics.endPass. All rendering must happen within a pass. love.draw is now called while a render pass to the main screen is active.
- Added love.graphics.renderPass, which is a wrapper for begin/endPass which calls the supplied function argument in between a begin/end. This is similar to the old Canvas:renderTo.
- Added love.graphics.isPassActive, getPassCanvases, getPassWidth, getPassHeight, and getPassDimensions.
- Added love.graphics.captureScreenshot.
- Added a new love.run callback love.drawpasses, which is called after love.update and before love.draw. It is the place to render to Canvases using beginPass or renderPass, since love.draw now always draws to the main screen.
- Renamed the ‘canvasswitches’ field in the table returned by love.graphics.getStats to ‘renderpasses’.
love.graphics.beginPass has the following variants (and renderPass mirrors them with an additional function argument at the end):
- love.graphics.beginPass(), begins rendering to the main screen without clearing it.
- love.graphics.beginPass(r, g, b [, a]), begins rendering to the main screen and clears the screen to the specified color.
- love.graphics.beginPass(canvas [, willstencil]), begins rendering to the specified Canvas without clearing it. love.graphics.stencil can only be used within the Canvas if ‘willstencil’ is true.
- love.graphics.beginPass(canvas, r, g, b [, a] [, willstencil]), beings rendering to the specified Canvas and clears it to the specified color. love.graphics.stencil can only be used within the Canvas if ‘willstencil’ is true.
- love.graphics.beginPass(info), where ‘info’ is a table in the following form:
{
{canvas [, r, g, b, a]}, — A canvas and an optional color to clear the Canvas to when the pass begins.
{canvas2, [r, g, b, a]}, — Additional Canvases and optional clear colors for multi-canvas rendering.
…,
stencil = false, — Optional boolean field to specify whether love.graphics.stencil is allowed within this pass. False by default.
}
The pass info table can be created once up-front and used for multiple beginPass/renderPass calls.
love.graphics.endPass can take an optional callback function argument, which causes endPass to capture the contents of the Canvas drawn to in the render pass to a new ImageData and passes it to the supplied function (this replaces Canvas:newImageData). This does not work on the main screen.
love.graphics.captureScreenshot replaces love.graphics.newScreenshot. It takes a callback function argument which causes love.graphics.present to capture the contents of the screen to a new ImageData and passes it to the supplied function. captureScreenshot can only be called before drawing to the main screen begins in the current frame (e.g. in love.keypressed, love.update, etc.)

This will simplify the code and make it more maintainable when OpenGL ES 2+ support is added, compared to using the deprecated VA functions on desktop GL and the generic VA functions on GLES.
