This blog is updated daily.
A general description is here.
The included version of xz's liblzma has been updated to 5.0.5.
‘R CMD javareconf’ now supports the use of symbolic links for ‘JAVA_HOME’ on platforms which have ‘realpath’. So it is now possible to use
R CMD javareconf JAVA_HOME=/usr/lib/jvm/java-1.7.0
on a Linux system and record that value rather than the frequently-changing full path such as ‘/usr/lib/jvm/java-1.7.0-openjdk-220.127.116.11.x86_64’.
Since ‘javareconf’ is used when R is installed, a simplified ‘JAVA_HOME’ can be supplied then.
On system where ‘mktime()’ does not set ‘errno’, the last second before the epoch could not be converted from ‘POSIXlt’ to ‘POSIXct’. (Reported by Bill Dunlap.)
