Changelog

Version 2.0.1 fixes preview failures after a cached AppHub download URL expired. Explicit previews now fetch a fresh signed manifest, while cached manifests are never reused beyond their signed `expires_at` timestamp.

The dashboard now scales to large repositories with a searchable, grouped package selector instead of rendering every translation in a long table. Selecting a package shows its language, revision, phrase count and status, with separate Preview and Install actions plus Roll back when a snapshot exists.

All new interface text is included in English, German, Croatian, Turkish, Russian and French.

Version 2.0.0 is a complete N.O.V.A. rebuild of the unpublished `[DZ] Language Installer` prototype.

This release replaces the public file repository and custom URL installer with a private, signed N.O.V.A. AppHub API. It adds exact add-on/language matching, previews, compatibility checks, native XenForo overwrite imports, rollback snapshots, audit history, background jobs, bulk compatible updates and daily non-destructive repository checks.

The administrator interface now includes English, German, Croatian, Turkish, Russian and French with automatic XenForo-language detection plus a manual selection and fallback.
