The team has a new release tagged 2021.05.18.0 which primarily fixes out-of-memory and sync issues
observed on older, less capable hardware, and other bug fixes. This is a required upgrade for all
miners and will be automatic for all Hotspots using the Helium firmware when we GA.
miner#776: Update blockchain-core and downgrade snapshot
The current blessed snapshot was downgraded back to 845281 because the previously blessed snapshot
was incomplete. Hotspots that have tried to load the new, bad snapshot will be stuck until a newer,
complete snapshot is minted by the chain.
miner#766: Add arm64 image builder
An ARM64 docker image builder was added to avoid long running build times.
blockchain-core#807: Parameterize snapshot generation
The change makes snapshot generation to be dependent on the currently configured
poc_challenge_interval chain variable. This limits snapshot generation to only those that include
required blocks as set by this variable.
blockchain-core#806: Clean checkpoint bugs and fix subnets
A few bugs related to ledger checkpoints were addressed and failing tests were fixed.
blockchain-core#805: Add missing light gateway chain var validation
A few missing chain variable validation functions were added after testing Light Hotspots on the Testnet.
