I have read the newsletter, im very sorry about the brexit, but @photonstorm didnt mention anything about the tile maps + WebGL shader :S :S
Quoting phaser 2.5.1 changelog (is this the fix for the tilemaps bug?);

Pixi Updates
Please note that Phaser uses a custom build of Pixi and always has done. The following changes have been made to our custom build, not to Pixi in general.
Removed _renderWebGL, _renderCanvas, getLocalBounds and getBounds from PIXI.DisplayObject, as they were only there to pass ancient jshint rules.
