Features (Velopack)

• Added a velopack updater type. Upload accepts the vpk-generated *-full.nupkg/*-delta.nupkg packages plus releases.{channel}.json; the feed's SHA1/SHA256/Size are ingested verbatim into a separate velopack block on each artifact (kept apart from the TUF hashes/length), packages are stored under velopack/{app}-{owner}/{version}/{channel}/{platform}/{arch}/ with their original filenames preserved.
• Added Velopack feed generation from MongoDB (velopack.BuildFeed): PascalCase Assets with absolute FileName URLs, published-only, all Fulls plus deltas whose immediate lower base is published (deltas across an unpublish/delete hole are dropped, Full remains as fallback).
• Added Mode 1 (CDN) write-through materialization to S3_BUCKET_NAME at velopack/{owner}/{app}/{platform}/{arch}/releases.{channel}.json, regenerated on upload, publish/unpublish, changelog/edit, and version/artifact deletion (velopack apps only). Empty feeds ({"Assets":[]}) are written to flush stale versions.
• Added Mode 2 (dynamic API) route GET /velopack/:owner/:app/:platform/:arch/*feed that builds the feed per request and caps it at the required intermediate version (via the existing migration-step lookup) when localVersion is supplied.
• Separated velopack installers from packages: installer files (anything that is not a .nupkg or releases.*.json) are now stored under a versioned installers/{stem}-{version}-{platform}-{arch}.{ext} key so the persisted artifact link is stable per version, while the flat, fixed-name installer (velopack/{owner}/{app}/{platform}/{arch}/{file}) is materialized on upload/update to keep pointing at the newest build. Added CopyObject to the storage interface (S3/base, MinIO, GCS) to back this copy-through.

Features (Global)

• Added staged rollouts.
