* Selections and find results are now rendered in the minimap.
* Model decorations now support `IModelDecorationOptions.minimap`, once set the decoration will be rendered in the minimap
* New editor options
*`autoClosingOvertype`: it controls whether the editor allows [typing over closing quotes or brackets](https://github.com/microsoft/vscode/issues/37315#issuecomment-515200477).
*`cursorSurroundingLines`: it controls how many visible lines to display around the cursor while moving the cursor towards beginning or end of a file.
*`renderWhitespace: "selection"`: the editor can render whitespaces only in selection.
### API changes
*`DeclarationProvider`: The declaration provider interface defines the contract between extensions and the go to declaration feature.
*`SelectionRangeProvider` Provide smart selection ranges for the given positions, see VS Code [issue](https://github.com/microsoft/vscode/issues/67872).
* CodeLensProvider should now return `CodeLensList` instead of `ICodeLensSymbol[]`.
*`DocumentSymbol` has a new property `tags` to support more types.
* View Zone id is now `string` instead of `number`.
* Localization support is brought back for AMD bundle. We lost the localization support when VS Code moved to the localization system but now AMD bundles ships the same localized strings VS Code localization extensions ship. For more details, please read [Monaco#822](https://github.com/Microsoft/monaco-editor/issues/822) and related [VS Code upstream issue](https://github.com/Microsoft/vscode/issues/71065)
*`LinkProvider.ProvideLinks` should now return `ILinksList` instead of `ILink[]`.
*`IEditorOptions.iconsInSuggestions` and `EditorContribOptions.iconsInSuggestions` are now replaced by `EditorContribOptions.suggest.showIcons`.
* We introduced `EditorContribOptions.suggest.maxVisibleSuggestions` to control maximum suggestions to show in suggestions widget.
*`EditorContribOptions.suggest.filteredTypes` is now introduced to allow suggestions to be filtered by the user. For more details, please read [vscode#45039](https://github.com/Microsoft/vscode/issues/45039).

* [Jonas Fonseca @jonas](https://github.com/jonas): Fix year for releases made in 2019 [PR #1388](https://github.com/Microsoft/monaco-editor/pull/1388)
* Added built-in support for AMD cross-domain web worker loading.
* Added API to remeasure fonts (`monaco.editor.remeasureFonts`) in case custom fonts are used and the editor is painted at a time when the fonts are not finished loading.
* Various editor improvements, such as an option to `renderFinalNewline`, or to have a `cursorSmoothCaretAnimation`
* Colorization support for Tcl, Pascal, Kotlin and GraphQL.
### Breaking changes
* We are no longer shipping WinJS.Promise, but we are shipping with a Promise shim (for IE11).
*`CompletionItem.range` is now mandatory. Most times, you can use `model.getWordUntilPosition()` to get a good range.
*`DefinitionLink` has been renamed to `LocationLink` and a couple of its fields have also been renamed.

* Improved typings in `monaco.d.ts` to better reflect null types.
### Breaking changes
* We are slowly migrating our code-base away from WinJS promises, so the exposed `monaco.Promise` API has been reduced to indicate that. We are setting up a Promise polyfill to cover browsers which do not have a native Promise implementation yet (i.e. IE11).
*`CompletionItemProvider.provideCompletionItems` and `CompletionItemProvider.resolveCompletionItem` have been modified to better reflect the API of VS Code. Both arguments and return type have changed.
*`SignatureHelpProvider.provideSignatureHelp` now receives an extra argument for the context.
* Various new editor options or tweaks to existing ones: `parameterHints`, `autoClosingBrackets`, `autoClosingQuotes`, `autoSurround`, `copyWithSyntaxHighlighting`, `tabCompletion`.

* A lot has changed w.r.t. how themes work in the editor, mostly driven by the work to support theming in VS Code. `editor.updateOptions()`**no longer accepts `theme`**; the theme can be changed via the newly introduced `monaco.editor.setTheme()`. Additionally, we recommend editor colors be customized via `monaco.editor.defineTheme()` instead of via CSS -- see [sample](https://microsoft.github.io/monaco-editor/playground.html#customizing-the-appearence-exposed-colors). The color names will be stable, while the CSS class names might break at any time.
* Support for the internal snippet syntax **has been discontinued** and snippet must now use the official, TextMate-like syntax. Find its grammar and samples [here](https://code.visualstudio.com/docs/editor/userdefinedsnippets#_snippet-syntax).
* Changed `IModel.findMatches` to accept a list of word separators.
* Changed the shape of the `IModelContentChangedEvent` emitted via `IModel.onDidChangeContent` to **now contain a batch** of all the changes that the model had.
* No longer using `transform: translate3d`, now using `will-change: transform` for browser layer hinting. Use the `disableLayerHinting` option if you have any trouble with browser layers (blurriness or high GPU memory usage).

* to the many others that have contributed PRs to [`vscode`](https://github.com/Microsoft/vscode) which have also made their way into the `monaco-editor`.
- [issue #385](https://github.com/Microsoft/monaco-editor/issues/385): Cannot add action to the left-hand-side of the diff editor
- [issue #386](https://github.com/Microsoft/monaco-editor/issues/386): Shortcuts for actions added via editor.addAction don't show up in the Command Palette
- [issue #387](https://github.com/Microsoft/monaco-editor/issues/387): Cannot change diff editor to a custom theme based on high contrast
- when entering an embedded mode (i.e. `nextEmbedded`), the state ending up in must immediately contain a `nextEmbedded: "@pop"` rule. This helps in quickly figuring out where the embedded mode should be left. The editor will throw an error if the Monarch grammar does not respect this condition.
- Before, token types would be rendered on the `span` node of text, and CSS rules would match token types and assign styling to them (i.e. color, boldness, etc.to style tokens)
- To enable us to build something like a minimap, we need to know the text color in JavaScript, and we have therefore moved the token style matching all to JavaScript. In the future, we foresee that even decorations will have to define their color in JavaScript.
- It is possible to create a custom theme via a new API method `monaco.editor.defineTheme()` and the playground contains a sample showing how that works.
- Token types can be inspected via `F1` > `Developer: Inspect tokens`. This will bring up a widget showing the token type and the applied styles.
### API changes:
#### Namespaces
- added `monaco.editor.onDidCreateEditor` that will be fired whenever an editor is created (will fire even for a diff editor, with the two editors that a diff editor consists of).
- added `monaco.editor.tokenize` that returns logical tokens (before theme matching, as opposed to `monaco.editor.colorize`).

-`monaco.editor.createWebWorker` now loads the AMD module and calls `create` and passes in as first argument a context of type `monaco.worker.IWorkerContext` and as second argument the `initData`. This **breaking change** was needed to allow handling the case of misconfigured web workers (running on a file protocol or the cross-domain case)
- Broken configurations (loading from `file://` or misconfigured cross-domain loading) now load the web worker code in the UI thread. This caused a **breaking change** in the behaviour of `monaco.editor.createWebWorker`
