compile warning on Linux and versioning

[tissatussa]

hi,

i see that you update the main code regularly .. compiling it on Linux succeeds, but i get this warning :

~/Compiled/blackmarlin$ make
EVALFILE=./nn/default.bin cargo rustc --release -- -C target-cpu=native --emit link=BlackMarlin

warning: `blackmarlin` (bin "blackmarlin") generated 1 warning
    Finished release [optimized] target(s) in 25.14s

the compiled binary is 28.8 Mb and shows v6.0 .. all other recent versions also show v6.0 .. it seems you don't use a development version, you just update "main" .. could it be handy to sub-version your next releases ? Eg. v6.0.1 etc.

The compiler warning has now been fixed.

About the versions, I don't really find versions meaningful other than for releases. The convention I follow is x.y where x is changed for each release, and y is changed if a bug fix is done on the release.
