Subject: [Rd] Different package versions on CRAN?
Message-ID: <427DB875.7010706@sciviews.org>

Hello,

I am making changes to some of my packages that are exposed in CRAN. 
Some changes make them incompatible with previous R versions [and I use 
Depends: R (>= 2.1.0)]. I suspect that, as soon as I will upload this 
new version to CRAN, it will replace the old one _everywhere_? However, 
the previous version of these packages remains perfectly usable with R 
1.9.X or 2.0.X. So, will this break the binaries in 
/windows/contrib/1.9|2.0, or will the latest valid binaries of my 
packages remain there, not updated? To put it another way, for a package 
Mypack with version 1.0-1 compatible with all R versions, when I upload 
Mypack version 2.0-0 compatible only with R 2.1.0, what will be the 
result on CRAN regarding Windows binaires?
1?) /windows/contrib/2.1/Mypack_2.0-0.zip
     /windows/contrib/2.0/Mypack_1.0-1.zip  # Not updated
     /windows/contrib/1.9/....              # Idem for all other subdirs

or

2?) /windows/contrib/2.1/Mypack_2.0-0.zip
     ??? error ??? because CRAN tries to update the package for other 
subdirectories and encounters Depends: R (>= 2.1.0) ???

Thanks,

Philippe
