+### Bug Fixes
+
+* **animations:** fix increment/decrement aliases example ([#18323](https://github.com/angular/angular/issues/18323)) ([48c1898](https://github.com/angular/angular/commit/48c1898))
+* **benchpress:** should still support selenium_webdriver < 3.6.0 ([#21477](https://github.com/angular/angular/issues/21477)) ([3c6a506](https://github.com/angular/angular/commit/3c6a506))

+* **compiler:** cache external reference resolution ([#21359](https://github.com/angular/angular/issues/21359)) ([c32e833](https://github.com/angular/angular/commit/c32e833))
+* **compiler:** make `.ngsummary.json` files idempotent ([#21448](https://github.com/angular/angular/issues/21448)) ([a931a41](https://github.com/angular/angular/commit/a931a41))
+* **core:** fix chained http call ([#20924](https://github.com/angular/angular/issues/20924)) ([54e7576](https://github.com/angular/angular/commit/54e7576)), closes [#20921](https://github.com/angular/angular/issues/20921)
+* **language-service:** Clear caches when program changes ([#21337](https://github.com/angular/angular/issues/21337)) ([cc9419d](https://github.com/angular/angular/commit/cc9419d)), closes [#19405](https://github.com/angular/angular/issues/19405)
+* **service-worker:** properly handle invalid hashes in all scenarios ([#21288](https://github.com/angular/angular/issues/21288)) ([51eb3d4](https://github.com/angular/angular/commit/51eb3d4))
+
+
+### Features
+
+* **core:** add binding name to content changed error ([#20352](https://github.com/angular/angular/issues/20352)) ([4556532](https://github.com/angular/angular/commit/4556532))
+* **forms:** handle string with and without line boundary on pattern validator ([#19256](https://github.com/angular/angular/issues/19256)) ([75f8522](https://github.com/angular/angular/commit/75f8522))

+# [5.2.0](https://github.com/angular/angular/compare/5.2.0-rc.0...5.2.0) (2018-01-10)
+
+
+### Bug Fixes
+
+* **bazel:** Give correct module names for ES6 output ([#21320](https://github.com/angular/angular/issues/21320)) ([9728dce](https://github.com/angular/angular/commit/9728dce)), closes [#21022](https://github.com/angular/angular/issues/21022)
+* **benchpress:** forward compat with selenium_webdriver 3.6.0 ([#21399](https://github.com/angular/angular/issues/21399)) ([6040ee3](https://github.com/angular/angular/commit/6040ee3))
+* **benchpress:** work around missing events from Chrome 63 ([#21396](https://github.com/angular/angular/issues/21396)) ([fa03ae1](https://github.com/angular/angular/commit/fa03ae1))
+* **common:** export currencies via `getCurrencySymbol` ([#20983](https://github.com/angular/angular/issues/20983)) ([fecf768](https://github.com/angular/angular/commit/fecf768))
+
+Note: Due to an animation fix back in 5.1.1 ([c2b3792](https://github.com/angular/angular/commit/c2b3792a3b5fa5215fe2ef7e0ac6511086ffe4c1)) which allows for nested :leave queries to work within animation sequences, all elements that are dynamically inserted (*ngIf, *ngFor, etc…) now contain the special CSS class: “ng-star-inserted”. This may cause failures within unit tests if there are any assertions that match against element.className directly. (An easy fix for this is to match using a regular expression instead of asserting the className string directly.)

+* **compiler**: split compiler and core. `@angular/platform-server` now additionally depends on `@angular/platform-browser-dynamic` as a peer dependency. ([#18683](https://github.com/angular/angular/issues/18683)) ([0cc77b4](https://github.com/angular/angular/commit/0cc77b4))
-* - the Angular compiler now requires TypeScript 2.4.x.
+* `platformXXXX()` no longer accepts providers which depend on reflection. Specifically the method signature went from `Provider[]` to `StaticProvider[]`.
-* router: `RouterOutlet` properties `locationInjector` and `locationFactoryResolver` have been removed as they were deprecated since v4.
-* compiler: the compiler option `enableLegacyTemplate` is now disabled by default as the `<template>` element has been deprecated since v4. Use `<ng-template>` instead. The option `enableLegacyTemplate` and the `<template>` element will both be removed in Angular v6.
-* core: `OpaqueToken` has been removed as it was deprecated since v4. Use `InjectionToken` instead.
-* `platformXXXX()` no longer accepts providers which depend on reflection.
