RStudio 2025.05.0

What's new in this version:

New:
RStudio:
- RStudio now uses an alternate display for R errors, warnings, and messages. In addition, output on stderr (e.g. R messages) are colored the same as regular output on stdout
- RStudio now displays a message when the GitHub Copilot completion limit has been reached (typically on a free Copilot account)
- RStudio now uses the RStudio project folder as the GitHub Copilot workspace root, providing more relevant completions
- RStudio now supports being built without GitHub Copilot support via the RSTUDIO_ENABLE_COPILOT CMake option
- On macOS, RStudio now uses the project directory / home directory for new RStudio sessions opened via the Dock menu’s “Open in New Window” command
- RStudio Desktop now supports opening files via drag and drop
- RStudio installation on Windows now registers icons for many supported file types
- RStudio for Windows binaries now have digital signatures
- RStudio now only writes the ProjectId field within a project’s .Rproj file when required. Currently, this is for users who have configured a custom .Rproj.user location.
- Added memory limit monitoring to RStudio (Linux only for now). If ulimit -m is set, this limit is displayed in the Memory Usage Report. As the limit is approached, a warning is displayed, then an error when the limit is reached. When the system is low on memory, the session can abort itself by shutting down in a controlled way with a dialog to the user. See the new "allow-over-limit-sessions option in rsession.conf
- RStudio now supports configuring a Kerberos Service Principal for the GitHub Copilot Language Server proxy settings
- RStudio now supports installation of Rtools45 for the upcoming R 4.5.0 release on Windows.
- RStudio now sets the environment variable SPARK_CONNECT_USER_AGENT = posit-rstudio in R sessions
- RStudio now sets the environment variable SF_PARTNER = posit_rstudio in R sessions

Posit Workbench:
- Changed memory limit enforcement of /etc/rstudio/profiles max-memory-mb setting from limiting virtual memory (ulimit -v) to resident memory (ulimit -m) for more accuracy. This allows a session to run quarto 1.6, which uses a lot of virtual memory due to its underlying virtual machine. Unfortunately, resident memory is only enforceable at the kernel level in Linux versions that support cgroups. To make up for the loss of kernel enforcement, RStudio warns the user and stops over limit sessions. For more robust kernel enforcement, configure memory limits in the Job Launcher using cgroups
- RStudio will now preserve unknown fields in .Rproj files that are added by future versions of RStudio
- RStudio now sends an interrupt git processes when stopped via “Stop” during a git commit, rather than just terminating the processes
- RStudio now properly displays R Markdown render errors with newer versions of the rmarkdown and rlang packages
- An SELinux policy module is now available, allowing Workbench to run when enforcement is enabled
- Migrated the Posit Workbench Admin Guide Hardening: Set Up SSL content into the Access and Security: Secure Sockets (SSL) topic to promote content discovery and single source of truth
- Adds secure browser storage to VS Code and Positron Pro sessions (vscode-server#174)
- Implemented User and Group profiles for VS Code and Positron Pro sessions
- Introduced custom bootstrap extensions to Positron Pro session to improve the Admin pre-configured extensions experience
- Introduced a new admin configuration UI in preview to modify and deploy distributed workload (Launcher) settings
- Updated to Launcher 2.19.0, which now writes an active state file to the filesystem for each config file loaded on reload or restart (launcher#1172)
- Consolidated the Posit Workbench Administrator Guide and Posit Workbench User Guide into a single site that includes a Posit Workbench documentation landing page
- Introduced audited Workbench jobs to provide auditing information alongside Workbench job output
- Sessions now set the environment variable SPARK_CONNECT_USER_AGENT to posit-workbench-rstudio, posit-workbench-positron, posit-workbench-jupyter, or posit-workbench-vscode depending on the session type
- Sessions now set the environment variable SF_PARTNER to posit_workbench_rstudio, posit_workbench_positron, posit_workbench_jupyter, or posit_workbench_vscode depending on the session type
- Updated dependencies for the JupyterLab extension to address security vulnerabilities
- Allow the option launcher-sessions-use-pam-password=1 in environments where launcher-ssl=0 if launcher-address points to the localhost
