An update on the adoption of serialization format 3:
R 3.5.0 (released yesterday) supports serialization format 3, but the
default is still format 2 to make the transition easier.
It is expected that the default will soon be changed to 3 in R-devel.
Packages thus must not depend on what is t
To reduce difficulties for people relying on automated tests set up to
build&"check --as-cran" using R-devel (e.g. travis-ci), the default
serialization version has been temporarily switched back to 2. Thank you
for your patience - according to svn history, the last change of the
serialization
As things stand now, package tarballs with vignettes that are built
with R-devel will not install in R 3.4.x, so CRAN can't accept them
and someone running R CMD check --as-cran should be told that. A
WARNING is appropriate.
Most likely what will change soon is that build/version.rds will be

This change poses difficulties for automated build systems such as
travis-ci, which is widely used in the R community. In particular
because this is a WARNING and not a NOTE this causes all R-devel
builds with vignettes to fail, as the default settings fail the build
if R CMD check issues a WARNING
