Weblab v0.8.1

Weblab v0.8.1

This patch release includes the Weblab FRR features introduced in
v0.8.0 and fixes offline topology validation with --image-dir.

The validator did not initialize the FRR catalog setting, causing an
AttributeError when checking installed VM/IOL image filenames. This also
blocked the v0.8.0 EXOS image and release workflow. The running server already
initialized this setting; the fault was in the standalone validation tool.
A regression test now checks the EXOS example with present and missing images.

Use v0.8.1 for the core, optional Agent and EXOS edition. Save configurations
and export backups before following the usual Compose upgrade procedure.
The existing v0.8.0 Git tag is unchanged.

Weblab FRR package

The optional node image remains
ghcr.io/weblab-network/weblab-frr:10.7.1-wl1, with the same immutable image ID
and the same tested LLDP, read-only SNMPv2c, routed VLAN and IPv4 VRRP support.
It has not been rebuilt for this validator fix.

Its binary archive, corresponding source archive, image.json and SHA256SUMS
remain attached to the v0.8.0 source release,
matching the image's provenance label and repository checksum lock. Verify with
sha256sum -c SHA256SUMS, then use docker load -i weblab-frr-linux-amd64.tar.gz
or pull the published image tag.

See the FRR setup and CLI guide for configuration,
persistence and supported scope. Existing FRR and LL2S images and saved lab data
retain their previous behavior.
