 * The `format` and `locale` arguments to `sliderInput()` have been removed. They have been deprecated since 0.10.2.2 (released on 2014-12-08).

-### New features and improvements
-
-* All uses of `list(...)` have been replaced with `rlang::list2(...)`. This means that you can use trailing `,` without error and use rlang's `!!!` operator to "splice" a list of argument values into `...`. We think this'll be particularly useful for passing a list of `tabPanel()` to their consumers (i.e., `tabsetPanel()`, `navbarPage()`, etc). For example, `tabs <- list(tabPanel("A", "a"), tabPanel("B", "b")); navbarPage(!!!tabs)`. (#3315 and #3328)
-
-* Numerous improvements tabset panels (i.e., `tabPanel()`, `navbarMenu()`, `tabsetPanel()`, `navbarPage()`, etc) (#3315):
-  * Closed #3322: `tabsetPanel()` and `navlistPanel()` gain `header`/`footer` arguments (inspired by `navbarPage()`'s already existing `header`/`footer`), making it easier to include content that should appear on every tab.
-  * Closed #3313 and #1823: More informative error when non-`tabPanel()`/`shiny.tag` objects are supplied to `...`.
-  * Closed #3321: New informative warning when `shiny.tag` object(s) are supplied to `...`. In this case we will continue to create an "empty" nav item and include the content on every tab, but the warning will mention the (new) `header`/`footer` args, which is likely what the user wants.
-  * Closed #3320: The HTML markup that `tabPanel()` et. al generate (for Bootstrap nav) is now Bootstrap 4+ compliant when used with `theme = bslib::bs_theme()`.
-  * Closed #1928: `NULL` values are now dropped instead of producing an empty nav item.
-  
-### Other improvements
+### Minor new features and improvements

 * Shiny's core JavaScript code was converted to TypeScript. For the latest development information, please see the [README.md in `./srcts`](https://github.com/rstudio/shiny/tree/master/srcts). (#3296)
