Upgrade notes for Shiny 1.13.0

New features

• Shiny now supports interactive breakpoints when used with Ark (e.g. in Positron). (#4352)

Bug fixes and minor improvements

• Stack traces from render functions (e.g., renderPlot(), renderDataTable()) now hide internal Shiny rendering pipeline frames, making error messages cleaner and more focused on user code. (#4358)

• Fixed an issue with actionLink() that extended the link underline to whitespace around the text. (#4348)
