1.7 release was great for finally addressing the issue of ever-growing size of produced binaries. [1] Moreover, some additional improvements were promised in 1.8 which I was looking forward to.

But after upgrading to 1.8 I am now observing 3-4% binary increase vs 1.7, so the trend is again reversed back to fatter binaries. :(
