### New

### Fixed
- ([#17737](https://github.com/rstudio/rstudio/issues/17737)): Restore the "Show .Last.value in environment listing" preference, which had stopped surfacing `.Last.value` in the Environment pane.
- ([#17777](https://github.com/rstudio/rstudio/issues/17777)): Fix "Import Dataset" from the Environment pane failing with "could not find function '.rs.digest'" when previewing a CSV (or other readr/readxl/haven source).

- ([#17278](https://github.com/rstudio/rstudio/issues/17278)): Fix a `data.table` returned invisibly from a `:=` update (e.g. `dt[, x := y]`) being auto-printed in notebook chunks, when its output should be suppressed as it is in the console.
- ([#17822](https://github.com/rstudio/rstudio/pull/17822)): Fix Posit Package Manager vulnerability badges no longer appearing in the Packages pane for sessions that point `options(repos)` at a PPM instance without Workbench PPM integration configured.
