萬衆矚目之下，ANGULAR 2終於正式發佈啦！

轉載：https://angular.io/

懷着期盼的心情，終於盼到了穩定版本，那麼我就能夠專心研究了，再也不爲不按期的修復煩惱咯。

今天，在 Google 總部一個特別的聚會上，咱們發佈了 Angular 2 的最終版， Angular 1 的全平臺繼任者。

「最終版」意味着什麼？意味着它的穩定性已經獲得了大範圍用例的驗證；意味着它已經針對產品化、文件尺寸和性能進行過優化；意味着藉助預編譯技術和內置的延遲加載機制，咱們能夠確信你能發佈出最快、最小的應用，而且橫跨瀏覽器、桌面和移動平臺；意味着爲開發人員準備的 Angular CLI 和風格指南獲得了大幅強化。

Angular 1 首先爲新興的 Web 技術解決了如何開發的問題。六年後的今天，開發人員面對的挑戰是：應用程序必須支持多種多樣、變幻無窮的設備。在此次發佈中，咱們有了更強力的路由器、表單和其它核心 API 。如今，你能夠爲任何平臺構建酷炫的應用了。也許你會更喜歡用本身的方式工做， Angular 一樣是模塊化並富有彈性的，這樣你就能夠自由使用你喜歡的第三方庫了——或是本身寫一個！

從一開始，咱們就在與開源社區合做來構築 Angular 。咱們要對大量的捐獻者表示由衷感謝！他們奉獻了大量的 Pull Request 、 Issues 和可重現的用例，他們爲各個設計決策展開探討和辯論，他們對咱們的各個 RC 進行了驗證和反饋。咱們真心但願能夠把大家中的每一位都帶到咱們的聚會現場，與咱們一塊兒慶祝這個偉大的里程碑！

下一步作什麼？

Angular 已經面世，咱們懷着激動的心情歡迎您成爲無數個用 Angular 構建應用程序的開發人員中的一位。那麼， Angular 下一步打算作什麼？

下面是一些 Angular 開發組近期要作的事：

• BUG 修復並對標記爲穩定（ stable ）的 API 進行非破壞性變動
• 針對您的用例寫更多的開發指南和在線例子
• 在動畫方面展開更多的工做
• Angular Material 2 庫
• 讓對 WebWorker 的支持走出實驗室
• 爲 Angular Universal 開發更多的特性，支持更多的語言
• 進一步提升速度，縮小體積

語義化版本

咱們得認可之前的 RC 版本標籤有些撲朔迷離。爲了讓您在 Angular 的穩定版中管理依賴更輕鬆，從今天的 Angular 2.0.0 開始，咱們將遷移到「語義化版本」規範。從此的 Angular 版本將遵循 semver 所描述的 MAJOR.MINOR.PATCH 方案：

1. 當對標爲穩定的 API 進行不兼容的變動時，增長主版本號（ MAJOR ），
2. 當添加了向後兼容的功能時，增長次版本號（ MINOR ），
3. 當以向後兼容的方式修復了 bug 時，增長補丁號（ PATCH ）。

遷移到語義化版本方案能夠確保咱們的組件和工具等生態圈能快速用到最新特性。雖然即便保持了一致而可靠的開發環境，產品級應用仍然會依賴於主版本之間的穩定性，但這對 BUG 修復和發佈新 API 來講仍然是顯著的優勢。
