Has the ABS for the usual non-flexible bricks changed in a documented way over the years? White bricks from the 1980s get yellowish, but white bricks from the 1990s don't. Current bricks seem shinier and have a bit different feel than bricks from the 1990s (even ones that aren't particularly worn).
