In our newsletters for exchanges we share news on IOHK’s latest development and releases as well as on the work being done specifically for exchanges. The previous newsletter can be found here.
IOHK released Cardano SL 1.2.1 and Daedalus 0.10.1 for Windows and MacOS on 14 June 2018. This bugfix release contains fixes for a few issues we had after Cardano SL 1.2.0 and Daedalus 0.10.0 release, mainly on Daedalus side, see Release Notes. On Cardano side engineers fixed character encoding problem in a Docker script for launching wallet backend; it is now independent of a locale of a host machine. We grateful to an exchange who raised this problem and allowed us improve our code. We appreciate your feedback.
We would like to remind that those exchanges that would like to integrate Cardano SL 1.2.1 can do this following the instructions in the Exchange Onboarding document. Exchanges that run earlier versions of Cardano SL can migrate to 1.2.1 following instructions in Migrating from V0 to V1 API section there.
Our next release Cardano SL 1.3.0 and Daedalus 0.11.0 has been cut off. We are going to deliver it within the next seven weeks. It includes, in particular, block syncing speedup done by our Network team. Engineers also completed the foundation work for integration testing and better test coverage. The next Linux beta release has been moved to post Cardano 1.3.0 main release.
The following release of Cardano SL 1.4.0 and Daedalus 0.12.0 is being planned. It will include Cardano Byron Testnet.
Our New Wallet team are working on a completely new implementation of the wallet. The implementation is based on and tested against our formal wallet specification, which gives us much greater confidence in its correctness. It has much improved performance compared to the original wallet. This implementation will form a solid basis for new features, including improved APIs for third parties to integrate with Cardano. Exchanges will benefit from the better performance and also from new input selection policies which will provide far better long-term unspent transaction output (UTxO) management.
We will be interested in exchanges that would like to try out our new wallet implementation once it's ready, as it'll have a lot of benefits for exchanges that are having performance problems with our current one.
