Blockchain Release: Minor Region Updates, Erlang Upgrade, and Snapshot Update

· 2 min read

The team has a new release tagged 2021.02.26.0. This is mostly minor from a Hotspot owner perspective but there are some major infrastructural improvements which will help us continue to maintain the code base including an upgrade to Erlang/OTP 23. We also included some region updates and a snapshot bump.

Support Erlang/OTP 23

Most of the miner and blockchain code base uses Erlang so this is a much needed upgrade to the next version of Erlang/OTP. We are now able to run on OTP 23 and anticipate upgrading to OTP 24 when it is released soon. This required changes to many of the repositories including miner, blockchain-core, and other dependencies.

Build changes to support new architectures

Thanks to the efforts of community member @jerm#0817 (Discord) / @ke6jjj we've been able to land several updates to dependencies to enable compilation of our blockchain on FreeBSD and the Apple M1. Thanks!

miner#652 Support Cayman Islands

Thanks to community member @w0ts0n who added support in miner for the Cayman Islands. I cyah wait to see the network grow!

miner#640 Support North Macedonia

We also added support for North Macedonia so hotspots can use the EU868 frequency range.

miner#656 Bump Snapshot

We have updated the snapshot block to 738001 to allow newly onboarded hotspots to sync faster to the current blockchain head block.

blockchain-core#732 Speedup Ledger CLI

Small update to help speed up a useful commandline interface that miner operators will appreciate.
