See <a href=\"https://github.com/angular/angular/pull/38931\">PR 38931</a>.</li>\n<li>TypeScript 3.9 is no longer supported. Please update to TypeScript 4.0. See <a href=\"https://github.com/angular/angular/pull/39313\">PR 39313</a>.</li>\n<li><code><a href=\"api/router/NavigationExtras\" class=\"code-anchor\">NavigationExtras</a>#preserveQueryParams</code> has been removed from <code>@angular/router</code>. See <a href=\"https://github.com/angular/angular/pull/38762\">PR 38762</a></li>\n<li><code>CollectionChangeRecord</code> has been removed from <code>@angular/core</code>. See <a href=\"https://github.com/angular/angular/pull/38668\">PR 38668</a>.</li>\n<li>We changed the default value for <code>relativeLinkResolution</code> from <code>'legacy'</code> to <code>'corrected'</code> so that new applications are automatically opted-in to the corrected behavior from <a href=\"https://github.com/angular/angular/pull/22394\">PR 22394</a>. Applications which use the current default are updated by a migration to specify <code>'legacy'</code> to ensure the current behavior is maintained when the default is updated. See <a href=\"https://github.com/angular/angular/pull/25609\">PR 25609</a>.</li>\n<li>Fixed a bug in the router where the arguments for <code>future</code> and <code>curr</code> snapshots were reversed in the call to <code>shouldReuseRoute</code> when processing child routes. Usually this ordering mistake doesn't matter because most implementations of <a href=\"api/router/RouteReuseStrategy#shouldReuseRoute\"><code>shouldReuseRoute</code></a> just do\nan equality comparison between <code>future</code> and <code>curr</code>. However, some implementations actually do rely on values specifically on\none of the two and will need to be updated. See <a href=\"https://github.com/angular/angular/pull/26949\">PR 26949</a>.</li>\n<li><code>ViewEncapsulation.Native</code> has been removed. Angular previously supported a view encapsulation mode <code>ViewEncapsulaion.Native</code> that was based on the v0 Shadow DOM Draft APIs.
