CHANGELOG.md

v0.1.0 - 2020-01-31

Note that this release is a complete breaking change, therefore node operators are instructed to upgrade.

This release mainly integrates the shared codebase between Hornet and GoShimmer called hive.go, to foster improvements in both projects simultaneously. Additionally, the autopeering code from autopeering-sim has been integrated into the codebase. For developers a Go client library is now available to communicate with a GoShimmer node in order to issue, get and search zero value transactions and retrieve neighbor information.
