🚀 8.1.1 的新功能

1️⃣ Updated Angular UI

1️⃣ 更新的 Angular UI

The Client App has been upgraded from Angular 16 to Angular 19, resulting in faster loading and rendering. This ensures a consistent experience across the UI and the Free Online Viewer.

[客戶端應用程式] 已從 Angular 16 升級至 Angular 19，帶來更快的載入與渲染。這確保了 UI 以及 [免費線上檢視器] 之間的一致體驗。

2️⃣ Disabled Hot Reload in Samples

2️⃣ 在範例中停用 Hot Reload

Sample applications often use local folders for caching. Previously, hot reload could mistakenly detect cache updates and refresh the app unexpectedly. To fix this, hot reload has been disabled in the launch settings of sample projects.

範例應用程式通常使用本機資料夾作為快取。先前，Hot Reload 可能錯誤偵測到快取更新而意外重新整理應用程式。為了解決此問題，已在範例專案的啟動設定中停用 Hot Reload。

3️⃣ NuGet Package READMEs

3️⃣ NuGet 套件 README

Each NuGet package now includes a README file that appears directly on its NuGet.org page, making it easier to understand usage without leaving the site.

每個 NuGet 套件現在都包含一個 README 檔案，會直接顯示在其 NuGet.org 頁面上，讓使用者不必離開網站即可了解使用方式。
