  packet was getting processed which was received by the disconnected neighbor

GoShimmer-0.1.0

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.

A detailed list about the changes in v0.1.0 can be seen under the given milestone.
