| # 2023 Q3 Hyperledger Fabric | ||
|
|
||
| # Project Health | ||
|
|
||
| Hyperledger Fabric is fairly mature and stable with a v2.5 Long-term support (LTS) release. | ||
| There is less churn and fewer commits than in years past, with continued focus on quality and support. | ||
| New features get proposed, approved, and implemented based on a community RFC process. | ||
| Mailing list activity is down a bit compared to prior years. | ||
| PRs and mailing list questions are generally turned around quickly. | ||
| There is significant Discord activity. | ||

| # Releases | ||
|
|
||
| LTS releases: | ||
| - v2.5 is the current LTS release with patch releases approximately quarterly. | ||
| - v2.2 is the prior LTS releases, critical fixes will be backported through 2023. | ||
|
|
||
| The Fabric [v2.5 announcement](https://lists.hyperledger.org/g/fabric/message/11754) encouraged users to upgrade to v2.5 so that they can keep getting fixes and updates that will eventually be targeted for v2.5.x releases only. | ||
| The announcement also indicated that the legacy Fabric SDKs (known as Fabric SDK for Node v2.2, Fabric SDK for Java v2.2, Fabric SDK for Go v1.0) are deprecated. | ||
| Users of the legacy SDKs are encouraged to evaluate the Fabric Gateway client API as a replacement. | ||
| The Fabric Gateway client API is the recommended SDK for client applications when using Fabric v2.4 or v2.5, and is available in Go, Node, and Java programming languages. | ||

| # Overall Activity in the Past Quarter | ||
|
|
||
| The project delivered fixes to the Fabric v2.2 (prior LTS) and v2.5 (current LTS) releases. See [release notes](https://github.com/hyperledger/fabric/releases) for details. | ||
|
|
||
| SmartBFT consensus algorithm has been integrated into the Fabric ordering service (main branch). Samples and documentation are being prepared for a Fabric v3.0 preview release. | ||
|
|
||
| An initial v0.0.0 of Go [fabric-admin-sdk](https://github.com/hyperledger/fabric-admin-sdk) has been released to help with programatic channel and chaincode management. | ||
| The project is evaluating the use of this admin SDK in a new and improved [fabric-cli](https://github.com/hyperledger/fabric-cli) that may eventually replace the original peer CLI commands. | ||
|
|
||
| Project members are helping to draft exam questions for the upcoming Hyperledger Fabric Certified Practitioner exam. | ||
|
|
||
| # Current Plans | ||
|
|
||
| The project expects to maintain and support v2.5 for an extended time period | ||
| and encourages all users to upgrade to v2.5 so that they can keep getting fixes that will eventually be targeted for v2.5 only. | ||
|
|
||
| The project intends to release a `v3.0.0-preview` release so that users can try out the initial SmartBFT feature, this will be Fabric's first Byzantine Fault Tolerant (BFT) consensus algorithm. | ||
| The plan is to get feedback on the SmartBFT feature, and also refactor the ordering service | ||
| so that there will be one orderer binary per consensus algorithm, which will be much more | ||
| extensible than the current approach of having one orderer binary that supports N consensus algorithms. | ||
| The project intends to refactor other code as well in an eventual v3.0 release, | ||
| and also remove some of the heritage features that have already been announced as deprecated in the [v2.x release notes](https://github.com/hyperledger/fabric/releases/tag/v2.5.0). | ||
| The refactoring work will take significant time, therefore most users are encouraged to use v2.5 which will be maintained and supported for an extended time period. | ||
