RStudio Preview Release Notes

RStudio v2021.09.0-preview+341.pro5 Preview Release Notes

“Ghost Orchid”, September 1st, 2021

  • Changed from semantic versioning to calendar based versioning (Pro #2652)
  • Projects containing a Python environment are now automatically activated (#9489)

Logging

  • In an effort to help make the RStudio Team products more cohesive, logging has been changed significantly.
  • By default, server logs will now be written to file instead of syslog. Warnings and errors will still log to syslog. This can be controlled by the warn-syslog parameter in logging.conf.
  • By default, server logs will now be written under /var/log/rstudio/rstudio-server.
  • Logs can now be written in JSON lines format.
  • Reloading the logging.conf configuration by sending a SIGHUP to the rserver process will now cause all RStudio managed subprocesses to also refresh their logging configuration.
  • Logging can now be partially configured using environment variables (RS_LOGGER_TYPE, RS_LOG_LEVEL, RS_LOG_MESSAGE_FORMAT, and RS_LOG_DIR).
  • Log files will now rotate by time in addition to the existing rotation by file size. This can be controlled by the rotate-days parameter in logging.conf.
  • For more information, see section 2 of the Admin Guide.

RStudio Workbench

  • Load-balancing configuration is now automatic, stored in the internal database, and doesn’t require editing config files. Added supporting rstudio-server list-nodes command to show users the node’s status according to the database. (Pro #2167)

  • Use separate database schema for open source RStudio Server instances (rstudio-os) and RStudio Workbench instances (rstudio) to avoid conflicts (Pro #2725)
  • Prevent user preferences from setting CRAN repos when allow-cran-repos-edit=0 (Pro #1301)
