This release also improves the parameters of rate-setter that should improve user-experience of issuing new blocks. It also contains various bugfixes and improvements, change of terminology e.g. message -> block etc. as well as replacement of grades of finality with confirmation state.

v0.9.1 - 2022-06-22

This release introduces the rate setter which allows nodes to estimate their fair rate of block creation and makes removing proof-of-work possible. Congestion is completely handled by the rate-setter and congestion control algorithms (capped at 30 BPS). Access mana is not decaying and is pledged to the node until it's re-pledged to another node. The release also includes new time concepts which make the network more resilient against mana going offline which in the past caused confirmations to stop permanently.

The snapshot has been changed and thus the ledger state is fully reset.

v0.9.0 - 2022-06-16

This major release introduces concurrency throughout the node with asynchronous events and parallelized booking. This is achieved with serix, a generic deterministic serialization library, and through generic thread-safe data models. The ledger and conflictDAG and output processing (introduction of UTXO VM) have been completely rewritten. The Blockfactory received a total revamp as well and tip selection should show better behavior in resolving conflicts. In addition, a bunch of unused modules and code have been removed rendering the project overall more readable. The short identifier of a nodeID has been adjusted to show the first 8 characters of the full identity.

The snapshot has been changed and thus the ledger state is fully reset.

v0.8.0 - 2021-11-05

This release introduces changes to the consensus mechanism. Specifically, a first implementation of pure On Tangle Voting (OTV), like switch, and the Grades of Finality (GoF) is included. This release does not entail algorithmic optimizations of these components. Therefore, it is to be expected, that performance degrades over time.

This is a breaking feature release. You must delete your current database and upgrade your node to further participate in the network. Applications that rely on confirmation need to adjust to be compatible with the newly introduced Grades of Finality.

The snapshot has been taken at 2021-11-05 12:18pm CET.

Changelog:

Add caching to CI operations
Upgrade hive.go and adjust codebase to use context for cancellation instead of channels
Add LRU cache to BranchDAG
Add new consensus mechanism
- Implement pure On Tangle Voting (OTV)
- Remove FCOB, FPC and timestamp voting with FPC from the dataflow
- Implement like switch
  - Make message layout more flexible and add parent blocks to accommodate like switch
  - Message syntactical validation
  - Adjust tip selection and message creation for like switch
  - Adjust booking of messages to execute like switch logic when inheriting branches
- Grades of Finality (GoF)
  - Marker confirmation with like switch
  - Remove Liked / Finalized / InclusionState references
  - Remove deprecated consensus manager and events
  - Inherit markers from strong and like parents
- Add conflicts page for node dashboard
- Adjust all unit and integration tests to use GoF
- Add new consensus integration tests
- Fix cMana weight provider with activity log for each node
- Add OTV metrics collection
- Optimize tracking of AW for branches and markers

v0.7.7 - 2021-10-09

This release does not include changes to the consensus mechanism and still uses FPC+FCoB.

This is a breaking maintenance release. You must delete your current database and upgrade your node to further participate in the network.

The snapshot has been taken at 2021-10-08 2pm CEST.

Changelog:

Changes the way the faucet plugin manages outputs in order to be able to service more funding requests.
Fixes a nil pointer caused when a re-org is detected but the RemoteLog plugin is not enabled.
Fixes an issue where the CLI wallet would no longer work under Windows.
Use Go 1.17.2 docker image

v0.7.6 - 2021-09-23

This release does not include changes to the consensus mechanism and still uses FPC+FCoB.

This is a breaking maintenance release. We urge community node operators to re-apply their config changes on top of config.default.json as many config keys have changed.

Most importantly, the node's identity seed is now defined via node.seed (previously autopeering.seed). The node will now store the private key derived from the seed per default under a separate peerdb database which must not be shared. If the node is started with a node.seed different to what an existing private key in a peerdb contains, the node panics; if you want to automatically override the already stored private key, use node.overwriteStoredSeed=true.

We have also created a more streamlined deployment for our infrastructure which means that IF provided endpoints have changed:

Service	Old	New
Analysis Server	ressims.iota.cafe:21888	analysisentry-01.devnet.shimmer.iota.cafe:21888
IOTA 2.0 DevNet Analyzer	http://ressims.iota.cafe:28080	http://analysisentry-01.devnet.shimmer.iota.cafe:28080
Autopeering Entry Node "2PV5487..."	[identity]@ressims.iota.cafe:15626	[identity]@analysisentry-01.devnet.shimmer.iota.cafe:15626
LogStash Remote Log	ressims.iota.cafe:5213	metrics-01.devnet.shimmer.iota.cafe:5213
Daily Database	N/A	https://dbfiles-goshimmer.s3.eu-central-1.amazonaws.com/dbs/nectar/automated/latest-db.tgz

Other changes:

Refactors codebase, mainly:
- Usage of time.Duration instead of numeric types for time parameters/config options variables etc.
- Normalization of all plugin names to camel case and without spaces
- Extracts some code from the MessageLayer plugin into a new Consensus plugin
- Use of dependency injection to populate plugin dependencies via https://github.com/uber-go/dig
Adds CI workflows to use GitHub environments to deploy develop branch changes and releases
Adds a check to see whether during the GoShimmer docker image build, the snapshot file should be downloaded
Adds a new plugin Peer which stores the node's identity private key in a separate database
Adds a broadcast plugin by community member @arne-fuchs simply providing a raw TCP stream of txs
Adds a lock to prevent multiple active instances of the CLI wallet
Adds improvements to the spammer precision
Adds timestamp filter
Fixes a bug where the TxInfo object passed to the mana booking could have a wrong totalAmount
Refactors the ./tools/docker-network to leverage docker profiles

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.
