v1.6.0-RELEASE

How do I upgrade?

If you weren't operating an RC (release candidate) node of IRI, you can just replace iri.jar with the latest version and then restart the node normally.

Upgrading from RC nodes

If you were running an RC node different than RC 15, we recommend removing your existing database entirely and starting with a database produced by IRI 1.5.6. You can download the latest 1.5.6 database here:
https://dbfiles.iota.org/mainnet/1.5.6/db-latest.tar

How to upgrade?

Clean database. remove your existing database entirely and start fresh. In this case, you should delete your mainnetdb folder and replace iri.jar with this latest version, then restart the node normally.

Keeping Your Database Post-Snapshot please follow the detailed instructions in the blog post above in order to keep your old database, but still benefit from the latest performance enhancements and bug fixes.

Notable changes:

Tag indexing (#728) - now when you query a node to findTransactions based on tags filter, both Tag and ObsoleteTag fields are scanned.

Running node on testnet with a single flag (#610) - now mainnet and testnet share the exact same codebase, and launching a node on the testnet is just a single flag, which the ability to configure private testnets - used to streamline IRI Development Lifecycle by having the same version from initial testing all the way to the mainnet.

TCP networking issues (#592) - over the course of this month we received quite a few contributions from community members improving TCP reliability and performance - most notably has been @footloosejava's contribution lately to IRI.

ZMQ sending issues (#569) - issues with ZMQ connections closing and IRI error messages are resolved, by having a single thread manage the socket.

Improved milestone solidity tracking (#486) - fixes node syncing issues and issues related to restarting, where the solid milestone incorrectly initialized to a high milestone number and seems stuck.
