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.
