The current stable version (adegenet_1.4-2) is available from CRAN.
You can also install adegenet from R by simply typing:
install.packages("adegenet", dep=TRUE)


Patches 
Patches correct minor bugs or implement new functionnalities, and will be included into the next CRAN release. It is recommended to use these versions instead of the current (CRAN) ones. Simply download the file (right click -> 'Save link as') in your working directory and type source("[your-patch-file.R]")  to use a patch.
addedFeatures.R: (for adegenet >=1.3-1) added features not included in the CRAN version of the package; includes conversion from seqTrack outputs to graphNEL objects. If you have a choice though, consider using current igraph implementation, which is probably better and still maintained.
