Virtual Registry 0.8.0

Released: 2026-03-05

Varnish version: 6.0.16r12

Added

Added Cluster option (premium).
Added dns_ttl option to remotes. This can be used to override the DNS resolution interval indicated by DNS records.
Added routes option to virtual registries. A route is a glob pattern (fnmatch) that enables more flexible registry routing, where only subdomain-based routing was available before. The subdomain routing still has the highest order of precedence, with routes being matched against the Host header in order of appearance.
Added preserve_subdomain option to remotes. When used, the incoming subdomain (final component) is appended to the remote Host header when fetching from the remote. The final hostname is also used for DNS and TLS SNI.
Added readonly option to virtual registries. When enabled, all uploads to the virtual registry are blocked.
Added extended support for Conan artifacts.
Added support for caching Ansible artifacts (roles and collections). This includes rewriting the download_url in manifests with the Virtual Registry base_url.
Added extended support for PyPi manifests. This includes rewriting absolute manifest URLs with the Virtual Registry base_url.
Added preserve_manifest option to virtual registries. When enabled, base_url insertion into manifests is disabled.

Fixed subdomain not being parsed correctly for single component Host headers with port.
Fixed parsing of Docker distribution protocol requests not separating query parameter from manifests referenced by SHA, leading to the being marked as “must-revalidate” instead of “immutable”.
Fixed Git v2 protocol ls-refs commands not being assigned a “resource_manifest” cache key.
