 * GCP: support using a single static key for all clusters and clients (must be located in `${AEROLAB_HOME}/sshkey(.pub)`; if it exists, will automatically be used).
 * GCP: Do not require zone for instances when setting labels.
 * Inventory List: expose gcp/aws/docker tags/labels and metadata in json output.
+* Net: Loss-Delay: upgrade tcconfig to `0.29.1` and make install optional (do not fail if install failed).
 * Partitioner: when configuring index on device, parse partition tree sprig configs and fix if required.
 * Upgrade: added `aerolab upgrade --bugfix` - will upgrade to latest fix version, not bleeding edge version.
 * Upgrade: improved `aerolab upgrade --edge` - always install latest pre-release if multiple are available.
