 * The `format` and `locale` arguments to `sliderInput()` have been removed. They have been deprecated since 0.10.2.2 (released on 2014-12-08).
 
-* Closed #3403: `insertTab()`'s `position` parameter now defaults to `"after"` instead of `"before"`. This has the benefit of allowing us to fix a bug in positioning when `target = NULL`, but has the drawback of changing the default behavior when `target` is not `NULL`. (#3404)

-## Learn about TypeScript
-
-The documentation by [TypeScript](https://www.typescriptlang.org/docs/) is a solid resource to know each and every bell and whistle. Most features have examples and convey the thoughts well.
-
-[TypeScript Deep Dive](https://basarat.gitbook.io/typescript/) is an online `bookdown`-like approach to TypeScript by "Microsoft MVP for TypeScript", Basarat Ali Syed. In his book, he goes through many examples of what you "should do", not necessarily "what is possible" like the [TypeScript docs](https://www.typescriptlang.org/docs/).
-
-## TypeScript StyleGuide
-
-Using the style guid from [TypeScript Deep Dive / StyleGuide](https://basarat.gitbook.io/typescript/styleguide), we extend it to have the usage be more familiar to R developers and preexisting Shiny development.  The goal is to produce consistent code that can be injested quickly.
-
-
-### StyleGuide
-
-* `null` vs. `undefined`
-  * Do not use `x === null` unless you truly mean it.
-  * Safer to use _truthy_ or _falsey_ checks instead. Ex: `if (x) {}`
-* `type` vs `interface`
-  * > Use `type` when you might need a union or intersection: `type Foo = number | { someProperty: number }`
-  * > Use `interface` when you want extends or implements: `interface FooBar extends Foo { bar: string;}`
-  * > Otherwise use whatever makes you happy that day.
-* Namespace
-  * `PascalCase`
-  * Ex: `Shiny`
-
-### Enforced (by `eslint`) StyleGuide
-
-* Variable
-  * `camelCase`
-  * Ex: `const hello = "world`
-* Class
-  * `PascalCase`
-  * Ex: `class InputBinding {}`
-* Type, Interface definitions:
-  * `PascalCase`
-  * Ex: `type BindingBase = {name: string}`
-  * Ex: `interface ShinyEventMessage extends JQuery.Event {}`
-* Enum
-  * `PascalCase`
-  * (Currently unused)
-* Single vs. Double Quotes
-  * While the JS community has decided on single quotes, R has decided on double quotes.
-  * > When you can't use double quotes, try using back ticks (`).
-* Annotate Arrays as `Type[]`
-  * Ex: `Foo[]` (vs `Array<Foo>`)
-* Annotate Records as `{[key: string]: valueType}`
-  * Ex: `const x: {[key: string]: number} = {a: 4}`
-  * Ex: Extend the unknown key definition with static keys: `const x: {known: string, [key: string]: number} = {known: "yes", a: 4}`
-* File Names
-  * `camelCase` - Enforced by `eslint`
-
-## Config files
+# Configure TypeScript
 
 The JavaScript community likes to build many small, effective packages that do minimal work. The unfortunate side effect is needing a config file for everything.
 
-All config files are located in the root folder to avoid opening two separate VS Code projects.
+## Config files
 
 * `.browserslistrc`
   * Used with `browserslist` and `core-js` to determine which polyfills should be incorporated.
 * `.eslintrc.yml`
   * Used with `eslint` and `prettier` to determine how the TypeScript files should be formatted and which lint failures should cause warnings, errors, or be ignored.
-* `.madgerc`
-  * Package used to determine if circular dependencies are found. `type` only imports are ignored as they are not included in the final bundle.
 * `.prettierrc.yml`
   * Used by `prettier` to know how to adjust code when a file is saved in VSCode or within `eslint`'s linting process.
 * `yarnrc.yml`

 Both JavaScript files will produce a sourcemap (`**.js.map`) that the browser will understand.  This will help you debug Shiny's JavaScript code within the browser and point back to the original TypeScript files.
 
-### Exported types
-
-`./extras/globalShiny.ts` contains global declarations to define `window.Shiny`, a globally available `Shiny` variable, and a globally available `Shiny` type. This file is in a parallel folder to `./src` to avoid `Shiny` from being globally accessable within the source code. However, this file is the default type defintion when the Type definitions are installed by external developers.
-
-#### External development
-
-When developing TypeScript projects that leverage Shiny, we recommend installing the Shiny TypeScript definitions to your package. To install the definitions, call
-
-```bash
-yarn add https://github.com/rstudio/shiny\#v1.7.0
-```
-
-, matching the GitHub tag to your current the Shiny CRAN release (ex: `v1.7.0`).  If you are asked to select a version of `@types/jquery`, please select the closest version.
-
-This will provide a global type defintion of `Shiny`, let your IDE know that `window.Shiny` is of type `Shiny`, and declare a globally available variable `Shiny` within your project. You **should not** need to import anything. Similar to `jQuery`, it should _Just Work_<sup>TM</sup>.
-
-When loading your compiled file, it should be loaded after Shiny is loaded. If you are using an `htmlDependency()` to add your code to the page, your script will automatically be loaded after has been loaded.
-
-
 ### GitHub Actions
 
 On push to the `master` branch or push to a Pull Request to the `master` branch, a GitHub Action will be run to make sure the bundled JavaScript code is up to date. If the source code does not compile to the exact same file, it will be committed an pushed back to the outdated branch. (This makes it so the full build tools are not necessary for small tweaks and comments. 🎉)
