Note that general font metrics are largely still based on the original (non-fallback) font, whereas glyph sizes are based on the fallback fonts when those are used to get the glyph.
Text objects are Drawable objects that represent text on the screen. They decouple text drawing from text parsing and vertex uploading, in a similar manner to SpriteBatches. They also optionally allow efficient batching of text from the same Font in different relative coordinate transformations, without having many draw calls.
Text objects currently have the following methods:
Text:set(textstring) -- replaces any existing text in the object with the new string.
Text:setf(textstring, wraplimit, alignmode) -- replaces any existing text with formatted text using the new string.
Text:getFont() -- gets the Font object used for this Text object.
Text:getWidth() -- gets the width in pixels of the most recently added text in the Text object.
Text:getHeight() -- gets the height in pixels of the most recently added text in the Text object.
Text:add(textstring, x, y, angle, sx, sy, ox, oy, kx, ky) -- adds a new string to the text object using the specified relative coordinate transformation, without replacing existing text. This behaves much like SpriteBatch:add.
Text:addf(textstring, wraplimit, alignmode, x, y, angle, sx, sy, ox, oy, kx, ky) -- adds a new formatted string to the text object using the specified relative coordinate transformation.
Text:clear() -- clears all text from the object.

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.

drawcalls: The number of internal draw calls made so far in the current frame.
canvasswitches: The number of times the active Canvas has been changed so far in the current frame.
texturememory: The approximate amount of video memory (in bytes) used by OpenGL textures created by Images, Canvases, and Fonts.
images: The number of active Image objects.
canvases: The number of active Canvas objects.
fonts: The number of active Font objects.
If mipmaps are enabled on image creation, the image will use the default mipmap filter (now 'nearest' by default.) Image:setMipmapFilter will error if the image was not created with mipmaps enabled.

Canvases and Images are now subclasses of the new Texture class.
Added setTexture and getTexture methods for Meshes, ParticleSystems, and SpriteBatches (the old set/getImage methods are deprecated but not removed.)
Canvas texture coordinates are no longer flipped.
