Following the release of R 3.1.3, I have pushed a new build of the OpenCPU server to launchpad, dockerhub and OBS. This update has no changes in OpenCPU itself, but includes updated versions of R, RStudio and R packages used by OpenCPU.
To upgrade your OpenCPU server:
sudo apt-get update
sudo apt-get dist-upgrade
If you are running OpenCPU in production and you do not want to receive automatic updates, make sure to remove or comment-out the opencpu repository in /etc/apt/sources.list.d/opencpu-opencpu-1_4-trusty.list on your server. The opencpu-1.4 repo now contains:
RStudio Server 0.98.1103
To list the versions of other R packages included with the cloud server have a look at the opencpu-lib directory on Github or navigate to /ocpu/info on your opencpu server.
