RStudio for Mac

• 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. (#2574)
• RStudio now displays a message when the GitHub Copilot completion limit has been reached (typically on a free Copilot account). (#15848)
• RStudio now uses the RStudio project folder as the GitHub Copilot workspace root, providing more relevant completions. (#15816)
• RStudio now supports being built without GitHub Copilot support via the RSTUDIO_ENABLE_COPILOT CMake option. (#15869)
• 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. (#15409)
• RStudio Desktop now supports opening files via drag and drop. (#4037)
• RStudio installation on Windows now registers icons for many supported file types. (#12730)
• RStudio for Windows binaries now have digital signatures. (rstudio-pro#5772)
• 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-pro#5019).
• RStudio now supports configuring a Kerberos Service Principal for the GitHub Copilot Language Server proxy settings. (#15823)
• 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-pro#7732)
• RStudio now sets the environment variable SF_PARTNER = posit_rstudio in R sessions. (rstudio-pro#7577)
