The release brings some much needed upgrades to existing features, even better performance, and extensions to new features such as HTLC. It is being recommended for both API and developer node operators, and the block producers (DPoS ‘Witnesses‘) which validate the network transactions.

ElasticSearch and Witness node operators take note

Operators of ElasticSearch nodes can upgrade to get support for Get operation by ID and serving get_account_history API.

Block producing nodes will benefit from being able to accept private key from a file.

All node operators will benefit from performance improvements (1764, 1875) and improved behavior when restarting a node (1832).

Users of the command line interface wallet (CLI) will benefit from the ability to sign messages on behalf of their account (1878).
