    What's New in Mocklet 0.2.0

    New Features

    Mock Templates
    You can now save any recorded mock as a reusable template. A new Templates tab in the extension panel lets you view, manage, and spawn mock services directly from
    saved templates. Each template includes a generated OpenAPI spec that can be previewed inline within the extension.

    Service Users
    Added a Service Users section to the panel, allowing you to manage automation credentials for your mock services without leaving the DevTools panel.

    Latency Emulation
    When creating a mock from a recorded HAR, the extension now preserves response latency from the captured network entries. A toggle in the mock creation form lets you
    enable or disable latency emulation per mock.

    Fixes & Improvements

    Security: removed dynamic innerHTML usage
    All dynamic HTML rendering has been rewritten to use safe DOM APIs (createElement, textContent, appendChild). This eliminates the unsafe innerHTML patterns that
    triggered AMO validator warnings in the previous release.

    "View in UI" button in OpenAPI viewer
    The OpenAPI spec modal now includes a direct link to open the spec in the Mocklet web UI.

    Better error messages
    JSON parse failures during HAR editing now show a specific error message instead of a generic one.

    Attribute injection fix
    Single quotes in dynamic HTML attributes are now properly escaped.
