The core developers have tagged a new 2021.10.27.0 Hotspot firmware release which includes new
functionality for Hotspots to automatically ingest latest on-chain snapshots. Makers, please see
the note below as there are some updates you'll need to incorporate to use this feature. This
release also reverts the var cache which was causing unforeseen issues and upgrades
blockchain-core to include many State Channel related optimizations.
This is a mandatory update for manufacturers to automatically ingest snapshots. We will no longer be blessing snapshots manually after this update.
Snapshot Source
This feature replaces the older snapshot loading mechanism and allows manufacturers to provide a JSON file that is always used to load latest snapshots. Here is an example of a file the core team uses to update our firmware controlled Hotspots.
This allows the hotspot to look for a file named snap-1072801 .This will enable Hotspots to
automatically load the latest defined snapshot (without a firmware update). Blessed snapshots are
still used in case this URL is not available. These endpoints can be configured with the new config
variables listed here,
specifically snap_source_base_url and fetch_latest_from_snap_source. If you, as maker, have a
custom sys.config or override file, you must update these configuration settings.
