+
+
+### BREAKING CHANGES
+
+* **packaging:** In v10, IE 9, 10, and IE mobile support was deprecated. In v11, Angular framework removes IE 9,
+10, and IE mobile support completely.
+Supporting outdated browsers like these increases bundle size, code complexity, and test load,
+and also requires time and effort that could be spent on improvements to the framework.
+For example, fixing issues can be more difficult, as a straightforward fix for modern browsers
+could break old ones that have quirks due to not receiving updates from vendors.
+* **platform-webworker:** @angular/platform-webworker and @angular/platform-webworker-dynamic
+have been removed as they were deprecated in v8
+* **common:** The `slice` pipe now returns `null` for the `undefined` input value,
+which is consistent with the behavior of most pipes. If you rely on
+`undefined` being the result in that case, you now need to check for it
+explicitly.
+* **common:** The typing of the `keyvalue` pipe has been fixed to report that for
+input objects that have `number` keys, the result will contain the
+string representation of the keys. This was already the case and the
+code has simply been updated to reflect this. Please update the
+consumers of the pipe output if they were relying on the incorrect
+types. Note that this does not affect use cases where the input values
+are `Map`s, so if you need to preserve `number`s, this is an effective
+way.
+* **common:** The signatures of the number pipes now explicitly state which types are
+accepted. This should only cause issues in corner cases, as any other
+values would result in runtime exceptions.
+* **common:** The signature of the `date` pipe now explicitly states which types are
+accepted. This should only cause issues in corner cases, as any other
+values would result in runtime exceptions.
+* **common:** The async pipe no longer claims to return `undefined` for an input that
+was typed as `undefined`. Note that the code actually returned `null` on
+`undefined` inputs. In the unlikely case you were relying on this,
+please fix the typing of the consumers of the pipe output.
+* **common:** The case conversion pipes no longer let falsy values through. They now
+map both `null` and `undefined` to `null` and raise an exception on
+invalid input (`0`, `false`, `NaN`) just like most "common pipes". If
+your code required falsy values to pass through, you need to handle them
+explicitly.
+* **router:** While the new parameter types allow a variable of type
+`NavigationExtras` to be passed in, they will not allow object literals,
+as they may only specify known properties. They will also not accept
+types that do not have properties in common with the ones in the `Pick`.
+To fix this error, only specify properties from the `NavigationExtras` which are
+actually used in the respective function calls or use a type assertion
+on the object or variable: `as NavigationExtras`.
+* **router:** This commit changes the default value of
+`relativeLinkResolution` from `'legacy'` to `'default'`. If your
+application previously used the default by not specifying a value in the
+`ExtraOptions` and uses relative links when navigating from children of
+empty path routes, you will need to update your `RouterModule` to
+specifically specify `'legacy'` for `relativeLinkResolution`.
+See https://angular.io/api/router/ExtraOptions#relativeLinkResolution
+for more details.
