Change of toolchain and reduction of size at output

Recently I updated atmel arm gnu toolchains from 4.7.3 version to 4.8.3 (on AS6.1_sp2).
I've watched after compile the output generated (bin file) is smaller in size than compiling previously with 4.7.3 toolchain (180KB vs 203KB). Apparently the new output works well as previous output, but I don't know if there's any or may be any problem using this new toolchain. The project configuration and source code have no changes between one and the other version of the toolchain. Does anybody know what is the reason of the size reduction?
